Book the flight with the exit rules in view

Airline refunds depend on who canceled, the size of a schedule change, the country and itinerary, and whether you accept an alternative. Save the offer and terms before purchase so you can show what changed.

1. Identify the seller and every operating airline

An itinerary can involve an online travel agency, a ticketing carrier and one or more operating airlines. Record all three. If separate tickets are combined, a missed second flight may not be protected when the first is delayed. Read the seller’s transfer or disruption guarantee instead of assuming one exists.

2. Compare the usable total

Enter passenger details only after comparing baggage, seat selection, payment fees, airport transfers and connection time. A fare that excludes the bag you must carry is not your price. Check airport codes carefully; some city searches combine airports hours apart.

3. Know the core U.S. refund rule

The U.S. Department of Transportation says a passenger is entitled to a refund when an airline cancels a flight or makes a significant change and the passenger chooses not to accept the alternative transportation or other compensation offered. DOT rules apply to flights to, from or within the United States as described in its guidance.

Do not click “accept” on a replacement, credit or voucher until you understand the effect. If you prefer a refund, make that request clearly through the channel responsible for the ticket.

4. Understand automatic refunds

DOT’s current refund rules require airlines and ticket agents to provide prompt automatic refunds when a covered cancellation or significant change occurs and the consumer does not accept the alternative. The original payment method generally matters. Read DOT’s current page for timing, exceptions and definitions rather than relying on an old social-media post.

5. Check the 24-hour reservation rule

For airline tickets purchased at least seven days before a flight’s scheduled departure to or from the United States, DOT requires airlines to offer either a 24-hour cancellation/refund option or a 24-hour hold without payment. This airline requirement does not necessarily apply in the same way to tickets booked through third-party agents, so check the seller’s displayed rule before paying.

6. Stress-test the connection

• Are all segments on one ticket?
• Do you have to collect and recheck baggage?
• Will you clear immigration or change terminals?
• Is transit authorization or a visa required?
• When is the next realistic flight if one segment fails?
• Who assists you during disruption—the airline, ticket agent or both?

A legal minimum connection time is not a promise that the trip will feel comfortable. Add margin for a high-value event or a destination with few replacement flights.

7. Save a booking record

Before purchase, save screenshots or a PDF showing:

• dates, local times, airport codes and flight numbers;
• the operating carrier for each segment;
• baggage and seat entitlements;
• change, cancellation and no-show terms;
• the full amount and currency;
• the seller’s support channel and any disruption protection.

After purchase, verify the reservation on the operating airline’s site when possible. A booking reference proves a reservation exists; a ticket number provides additional evidence that the ticket was issued.

8. If the trip changes

1. Capture the original and new itinerary.
2. Decide whether you want the proposed alternative or a refund before accepting anything.
3. Contact the ticket seller and airline using written channels when available.
4. Keep timestamps, case numbers and receipts.
5. If a covered U.S. refund is not provided, use the DOT consumer complaint process described on its site.

Bottom line

A strong booking is not merely cheap. It has workable connections, known baggage, clear seller responsibility and a loss you can afford if you voluntarily cancel. For airline-caused cancellations or significant changes on covered U.S. itineraries, consult DOT’s current guidance before accepting a credit you do not want.
