• Flight delays and rerouting due to conflict are typically driven by safety regulations, including airspace restrictions issued by authorities like the FAA.

• According to the U.S. Department of Transportation (DOT), U.S. law generally requires airlines to provide refunds for canceled or significantly changed flights if a passenger chooses not to travel, though specific circumstances may vary.

• Travel insurance may reimburse certain delay or interruption-related expenses, depending on the plan terms, timing of purchase, and applicable exclusions.

In situations of geopolitical conflict, airlines may adjust routes, delay departures, or cancel flights to comply with safety protocols. Conflict situations and government responses can evolve rapidly, and airline decisions are often based on real-time safety assessments rather than predictable schedules. These changes can affect travelers with little notice, turning a straightforward trip into a more complex journey.

If your flight is rerouted or delayed due to a conflict, it can raise several questions. Will you reach your destination on time? What options does the airline provide? How do you handle unexpected expenses or last-minute changes?

Understanding how these disruptions work and what steps you can take can help you respond more effectively. In this article, we’ll walk through what typically happens during conflict-related flight disruptions and how you can prepare for them with more clarity.

How the US Government Decides Which Skies Are Off Limits

Before you can understand why your flight was canceled or rerouted, you need to understand who made that call and why.

The FAA's Role

The FAA has the primary U.S. government authority to protect U.S. civil aviation from potentially hazardous situations in domestic and international airspace. The FAA has broad oversight responsibilities for U.S. operators regardless of where they operate around the world and has developed procedures for identifying and responding to an international situation resulting from a conflict situation, heightened tensions, military or paramilitary action, and/or a weapons-related hazard in foreign or international airspace.

That authority reaches further than most travelers realize. It does not just cover American skies. If you are a passenger on a U.S. airline flying from New York to Dubai, the FAA's rules follow that plane the entire way.

The agency does not operate alone. While the primary responsibility for issuing advisories and prohibitions for potentially hostile situations threatening civil aviation rests with the air navigation service provider for the affected airspace, the FAA may issue an Advisory or Prohibitory NOTAM for U.S. operators, U.S.-registered civil aircraft, and FAA-certificated airmen, if the FAA Administrator deems action necessary for safety or national security.

What a NOTAM Actually Does

A NOTAM, or Notice to Air Missions, is the primary tool the FAA uses to restrict flight operations in dangerous areas. These airspace restrictions restrict aircraft from operating without permission in a certain area for a limited time, and are issued for safety or security purposes.

In conflict situations, the FAA can escalate from an advisory NOTAM to a full prohibition. Current U.S. flight prohibitions and advisories are in place for airspace covering Tehran, Kabul, Libya, Somalia, North Korea, Haiti, and other regions affected by conflict or security threats. These are not suggestions. They are legally binding on all U.S. carriers and certificated airmen.

When a prohibition is in place, it applies broadly. A Special Federal Aviation Regulation applies to all U.S. air carriers or commercial operators, all persons exercising the privileges of an airman certificate issued by the FAA, and all operators of aircraft registered in the United States.

The Team Behind the Decisions

You might wonder how quickly and reliably the FAA can assess a rapidly changing conflict situation. The answer is a standing interagency team. The FAA has a dedicated team of experts, the Chapter 31 Crisis Response Working Group, to address potentially hazardous situations outside the United States. This cross-functional team of technical experts is chaired by the Office of International Affairs and includes specialists from National Security Programs, Flight Standards, Air Traffic Organization, Office of Rulemaking, and the Office of the Chief Counsel. (DOT OIG)

You can see every active NOTAM and Special Federal Aviation Regulation in real time on the FAA's Prohibitions, Restrictions and Notices page at Prohibitions, Restrictions and Notices. Checking this page before an international trip is one of the most practical steps any American traveler can take.

What the State Department Tells You (and Why It Matters for Your Flight)

The FAA protects the planes. The State Department protects you, the traveler, by making sure you have accurate information before you step foot in a country where conditions could deteriorate quickly.

The Travel Advisory System

A Travel Advisory is a report from the U.S. Department of State that describes the risks and recommended precautions for U.S. citizens in a foreign destination. The Department of State has no higher priority than the safety and security of U.S. citizens overseas.

The system uses four levels that every American traveler should memorize before booking international flights. Level 1 means exercise normal precautions. Level 2 means exercise increased caution due to specific risks. Level 3 means reconsider travel due to serious safety and security concerns. Level 4 is the highest advisory level due to life-threatening risks, where the U.S. government may have very limited or no ability to help, including during an emergency.

The advisory level for your destination directly affects how airlines make routing decisions, and may also influence how travel insurance coverage is applied, and how much government assistance you can expect if you get stranded.

The "Unrest" Indicator

Within each advisory, the State Department flags specific risk types with letter indicators. The one most relevant to conflict travel is the Unrest indicator. The Unrest indicator signals that U.S. citizen safety may be threatened by political, economic, religious, or other instability and violence. Demonstrations, protests, or armed conflict may threaten your physical safety and prevent you from accessing help or evacuating the area.

When you see a Level 3 or Level 4 advisory with a U indicator, you are looking at a situation where airspace closures, flight cancellations, and potential inability to reach a U.S. embassy are all real possibilities. In these scenarios, some travel insurance plans may include exclusions for known or foreseeable events, so timing and policy details matter.

These advisories are informational and do not determine insurance coverage. Travel insurance benefits depend on the specific terms, conditions, and exclusions outlined in the policy.

STEP: The Free Tool Almost Nobody Uses

The State Department's Smart Traveler Enrollment Program (STEP) is a free service that sends you email updates and alerts from U.S. embassies and consulates abroad. You enroll at step.state.gov before your trip, and the nearest embassy or consulate will contact you directly if conditions deteriorate, including notifying you about airspace changes that could affect your departure.

The STEP program is useful for tourists who want to stay aware of local threats, business travelers who need to stay updated on changing conditions, students abroad, and long-term residents who need critical safety guidance from the U.S. embassy or consulate while living abroad. US Department of Transportation

Enrollment also helps the State Department locate and assist you in a crisis. If you are stranded and phones are down, being in the STEP system means the nearest U.S. mission has your information on file and can try to reach you through your emergency contact at home.

For real-time guidance when conflict erupts, Americans in the Middle East and other affected regions should follow the latest guidance from the nearest U.S. embassy or consulate and can contact the State Department's 24/7 Task Force at +1-202-501-4444 from abroad, or 1-888-407-4747 from within the U.S. and Canada.

What Are Your Refund Rights Under US Law?

This is where most travelers lose thousands of dollars simply because they do not know the rules. The good news is that U.S. law is actually quite strong on refunds, and the landmark 2024 DOT rule made it significantly stronger.

The Automatic Refund Rule: What Changed in 2024

In April 2024, the U.S. Department of Transportation issued a final rule to address persistent issues reported by airline passengers who were trying to obtain refunds. Prior to this rule, airlines were permitted to set their own standards for what constituted a qualifying change.

According to the DOT, the updated rule aims to create more consistency for passengers by defining when refunds are expected and requiring airlines to issue them automatically in qualifying situations.

The Rule That Applies Regardless of Cause

One important aspect of DOT guidance is that when an airline cancels a flight or makes a significant change, passengers may be eligible for a refund if they choose not to accept the alternative offered. This generally applies regardless of the reason for the disruption, including events outside the airline’s control, such as conflict or airspace restrictions.

However, individual situations may vary, and travelers should confirm details directly with the airline or refer to DOT resources for the most current guidance.

What Counts as a "Significant Change"

Under DOT regulations, a change may include a domestic flight departing 3 or more hours earlier or arriving 3 or more hours later than scheduled; an international flight departing 6 or more hours earlier or arriving 6 or more hours later than scheduled; a change to the origination or destination airport; or an increase in the number of connections.

These thresholds are based on DOT guidance and may be applied differently depending on the airline’s policies and the specific situation.

The Montreal Convention for International Flights

For Americans on international itineraries, there is an additional layer of protection. On international itineraries, passengers may be able to recover reimbursement under Article 19 of the Montreal Convention for expenses resulting from a delayed or canceled flight by filing a claim with the airline. If the claim is denied, you may pursue the matter in court if you believe that the carrier did not take all measures that could reasonably be required to avoid the damages caused by the delay.

This matters for conflict situations because it gives you a legal avenue to recover not just the ticket cost but also consequential expenses like hotels and meals if the airline failed to act reasonably.

What Airlines Owe You Beyond a Refund

A refund covers the cost of your ticket. But what about the hotel you had to book when you got stranded, the meals you paid for during a six-hour delay, or the transportation to an alternative airport? Here is where the distinction between "within airline control" and "outside airline control" becomes critically important.

The FlightRights Dashboard

The U.S. Department of Transportation has created a dashboard to ensure the traveling public has easy access to information about services that U.S. airlines provide to mitigate passenger inconveniences when the cause of a cancellation or delay was due to circumstances within the airline's control. You can find it at flightrights.gov.

All 10 major U.S. airlines guarantee free rebooking and meals, and nine guarantee hotel accommodations when an airline issue causes a significant delay or cancellation. These are commitments the airlines added to their customer service plans that DOT can legally ensure they adhere to.

What to Do Right Now If You Are Stranded

Even where airlines are not legally required to cover your expenses, many will do so voluntarily, especially for premium cabin passengers or frequent flyers. Always ask. Keep every receipt for every expense you incur, including hotels, meals, transportation, and communication costs. Submit those receipts to the airline in writing and request reimbursement. You may not receive it, but you cannot receive it if you never ask.

If those expenses are not reimbursed by the airline, travel insurance with flight coverage may help cover certain eligible costs such as meals, accommodations, or local transportation during a covered delay, subject to plan terms, conditions, and exclusions.

Although not required by DOT, airlines often offer to rebook consumers on alternative flights following a flight cancellation or significant delay. When making these offers, airlines must let you know that you are entitled to a refund if you do not accept the offer. If you reject the offer or do not respond to the offer, a refund must be issued to you automatically without you having to make a request.

Coverage varies by plan, and only the policy document determines what is covered. Travelers should review their plan details carefully to understand eligibility and limitations.

Flight Status Notification Requirements

If the flight is scheduled to depart within 7 days, airlines are required to provide status updates 30 minutes or sooner after the airline becomes aware of a status change. The flight status information must, at a minimum, be provided on the airline's website and by the airline's telephone reservation system, and the airline must update all flight status displays and other sources of flight information at U.S. airports that are under the airline's control within 30 minutes after the airline becomes aware of the problem.

This means if your airline knew your flight was affected and did not notify you promptly, that failure to notify is itself a violation you can report to DOT.

Your Step-by-Step Action Plan If Your Flight is Delayed or Rerouted

The following information is provided for general educational purposes only and does not constitute legal or governmental advice. Travelers should consult official sources such as the U.S. Department of Transportation, FAA, or State Department for the most current guidance.

Understanding typical steps travelers consider in these situations can help you respond more effectively:

• Before You Book: Visit travel.state.gov and review the current Travel Advisory for your destination and every country you are connecting through. Pay particular attention to Level 3 and Level 4 advisories, and look for the Unrest indicator. Then check Prohibitions, Restrictions and Notices to see whether any active NOTAMs or Special Federal Aviation Regulations affect your route. Enroll in STEP at step.state.gov for every country in your itinerary. It takes less than five minutes and costs nothing. This single step gives you direct, real-time alerts from the U.S. embassy if conditions change.

• In the Days Before Departure: Re-check the departure and arrival times of your flights a few days before your trip, as schedules sometimes change. On international trips, some airlines may require that you reconfirm your onward or return reservations at least 72 hours before each flight, and if you do not, your reservations may be canceled. Monitor both your airline's app and the State Department's page for your destination. If a Level 4 advisory is issued or a new FAA prohibition is posted for airspace on your route, contact your airline immediately rather than waiting for them to contact you.

• If Your Flight Is Canceled or Significantly Changed: Know that under the 2024 DOT rule, you have three choices: accept the rebooked flight, accept a travel credit or voucher (which must be valid for at least five years), or request a full cash refund. If your flight is canceled and the airline does not rebook you on a new flight, or you do not proactively accept alternative compensation such as a flight voucher or miles, you are entitled to a refund regardless of the reason for the cancellation. Do not accept anything you do not fully understand. Ask the airline representative explicitly: "Is this a refund to my original form of payment, or is it a travel credit?" The answer matters.

• If You Are Stranded Abroad: Contact the nearest U.S. embassy or consulate immediately. Their contact information is available at travel.state.gov for every country. Americans who need consular information or assistance can call the State Department's 24/7 Task Force at +1-202-501-4444 from abroad, or 1-888-407-4747 from within the U.S. and Canada. Keep all receipts for all expenses. File them with your airline in writing. If the airline denies reimbursement and you believe you are entitled to it, escalate to DOT.
  
  If you have a travel protection plan, you can also contact the plan’s travel assistance service provider. They may help coordinate next steps such as rebooking flights, locating accommodations, or providing guidance during the disruption.

• If You Need to File a Complaint: If you have a problem obtaining a refund that you believe you are entitled to receive, you may file a complaint with DOT. The complaint portal is at transportation.gov/airconsumer. DOT's Office of Aviation Consumer Protection can direct the airline to respond to your complaint directly and requires a copy of the response to be provided to the agency as well.

You should review your travel insurance plan documents to understand whether conflict-related disruptions are covered, as coverage depends on the policy terms, conditions, and exclusions, including when the plan was purchased.

FAQs About Flight Issues Due to Regional Conflicts

If my flight is canceled because of a conflict or airspace closure, am I entitled to a refund even if I have a non-refundable ticket?

Yes. If an airline cancels a passenger's flight or makes a significant change in the flight, regardless of the reason, airlines are required to provide a prompt refund to a ticketed passenger, including those with non-refundable tickets, should the passenger choose not to accept the alternative offered. The non-refundable designation applies when you voluntarily cancel. It does not apply when the airline cancels or significantly changes your flight.

Does travel insurance cover flight delays caused by conflict?

Travel insurance may reimburse certain expenses related to flight delays if the delay meets the conditions outlined in the plan. Coverage can depend on factors such as the cause of the delay, timing of purchase, and specific policy terms and exclusions.

Does travel insurance cover cancellations due to war or conflict?

Some travel insurance plans include exclusions related to war or undeclared conflict. In certain cases, coverage may apply if the event was unexpected and met specific conditions. It is important to review the policy details carefully.

Coverage varies by plan, and only the policy document determines eligibility. Travelers should review their plan details carefully to understand how these situations are addressed.

My flight was rerouted and arrived 8 hours late. Do I qualify for a refund if I still took the flight?

If you chose to take a significantly delayed or changed flight or an alternative flight offered by the airline, you are not entitled to a refund under DOT rules. The refund right applies when you decline to travel or decline the alternatives being offered. If you accepted the rerouted flight and flew, the refund right does not apply to the ticket price, though you may still have a claim for ancillary services that were not delivered.

The airline offered me a travel voucher instead of cash. Do I have to accept it?

No. Cash refunds, not vouchers or credits, must be automatic when passengers are owed. If you do choose a voucher, it must be valid for at least five years. You can simply decline the voucher and request a cash refund to your original form of payment.

I booked through a third-party website like Expedia or Google Flights. Do the same refund rules apply?

Under the final rule, U.S. and foreign air carriers must provide prompt automatic refunds and ticket agents must provide prompt refunds upon request when airlines cancel or significantly change their flights and consumers do not accept the alternatives offered. The obligation falls on both the airline and the ticket agent. That said, the process is typically faster and simpler when you book directly with the airline.

How do I know if there is an FAA flight prohibition affecting my route?

Check faa.gov/air_traffic/publications/us_restrictions. A copy of FAA's current NOTAMs and links to the Special Federal Aviation Regulations can be found at the FAA's Prohibitions, Restrictions and Notices page, which is the official public registry of all active flight restrictions, including those tied to conflict zones.

What is the State Department's STEP program and why should I enroll?

STEP is a free service that sends you email updates and alerts from U.S. embassies and consulates abroad. When you subscribe to STEP, you get important updates and alerts from the U.S. embassy or consulate for the destination you are visiting or living in. Enrollment also allows the embassy to contact your emergency contact at home if you are unreachable. You can enroll at step.state.gov before any international trip.

If I am stranded abroad due to conflict, what U.S. government help is available?

Americans who need consular information or assistance can call the State Department's 24/7 Task Force at +1-202-501-4444 from abroad or 1-888-407-4747 from the U.S. and Canada. The nearest U.S. embassy or consulate can help you understand your options, connect you with local resources, and assist with emergency documentation. However, you should have a plan to leave in an emergency that does not depend on U.S. government help, as the government may have limited ability to assist in a rapidly evolving conflict situation.

Where do I file a complaint if an airline refuses to give me a refund I am owed?

File directly with the DOT's Office of Aviation Consumer Protection at transportation.gov/airconsumer. The office can require the airline to respond to your complaint and monitors patterns of non-compliance that can lead to enforcement action.

Disclaimer: Travel insurance coverage is subject to policy terms, conditions, limitations, and exclusions. Coverage availability, benefits, and definitions vary by plan and by state.
