Missed Flight? What to Do Now and What Happens to Your Ticket

A missed flight is a departure you failed to board, while an airline cancellation is a flight the carrier did not operate. That difference controls what happens next. Your best move is to contact the operating airline immediately, explain whether you are still traveling, and ask it to protect the rest of the booking.

What to do after a missed flight

1. Contact the operating airline now. Use its app, phone line, airport desk, or gate staff. Ask for the earliest available rebooking option under your ticket's fare rules.
2. Protect every later segment. Tell the agent about onward and return flights on the same reservation. Do not assume those bookings remain active after a no-show.
3. Confirm the cost before accepting. Ask whether the airline is offering a confirmed seat, standby travel, a ticket credit, or a new fare. Request the terms in writing or save the message in the app.
4. Track your checked bag. Ask the airline where the bag will be held or routed. TSA directs baggage problems to the airline, while its own Lost and Found handles items left at checkpoints or missing from checked baggage.
5. Save the new boarding pass offline. Check the terminal and gate again, then allow time to complete any screening the new route requires.

Who caused the disruption?

Situation	What the official rule says	What to ask for
You arrived late and the flight operated	The U.S. Department of Transportation says a traveler with a nonrefundable ticket is not entitled to a refund merely because the traveler arrived late.	Ask the airline what voluntary rebooking, standby, or ticket-value options your fare permits.
The airline canceled the flight	The U.S. DOT says you are entitled to a refund if you decline to travel and do not accept a credit, voucher, or other compensation.	Choose between the airline's alternative travel and the refund you are due.
The airline significantly delayed or changed the trip	The U.S. DOT says a refund applies when the change is significant and you choose not to travel or accept the alternatives offered.	Ask the airline to explain both the rebooking offer and the refund option before you decide.

This distinction matters when speaking with an agent: say whether you missed an operating flight or the airline disrupted your itinerary. Use the precise situation rather than calling every problem a cancellation.

Can a missed flight cancel the rest of the itinerary?

It can, depending on the airline's contract. Delta's U.S. Contract of Carriage, for example, says that if a passenger does not appear for any flight without changing or canceling before departure, Delta may cancel all remaining flights on that itinerary. Its contract also says the ticket may have no remaining value except where law requires otherwise.

That is a Delta rule, not a universal promise about every carrier. Ask your airline to confirm each onward and return segment by flight and date. If the booking came through a travel agent, contact the operating carrier for the immediate airport problem and the merchant shown on your payment record for any refund it is responsible for processing.

Will the airline refund a missed flight?

Not automatically. The U.S. DOT separates a passenger's late arrival from an airline-caused cancellation or significant change. If a nonrefundable ticket holder arrives late while the flight runs as scheduled, DOT says the traveler is not entitled to a refund. A fully refundable fare remains governed by its terms.

If the airline canceled or significantly changed the flight and you reject the proposed alternative, DOT says the refund must go back automatically. If you accept and travel on the alternative flight, DOT says you are not entitled to a refund under those rules. This is why you should understand the offer before tapping an acceptance button.

What if you missed a connection?

First, find out whether the operating airline has already rebooked you. Then verify the full itinerary, not just the next departure. The airline's answer depends on the ticket, the cause of the missed connection, and its contract. Keep delay or cancellation notifications because they show whether the disruption began with the airline rather than with your own late arrival.

If you must pass through security again, follow the current TSA instructions at that checkpoint. TSA says its procedures can change, and an item that is generally permitted may still receive extra screening or be stopped for security concerns. For packing details, use the official TSA guidance and our airport security screening guide.

What if your bag or device went on without you?

Ask the airline to trace checked baggage and tell you where it can be collected. If you left a device or another item at the security checkpoint, use TSA Lost and Found. TSA says its airport contacts cover checkpoint items and items missing from checked baggage; property left in another part of the terminal belongs with the airport's own lost-and-found service. See our airport lost-and-found guide for the right handoff.

Before you leave the counter

• Confirm the flight, date, airport, terminal, and reservation status.
• Ask whether every onward and return segment remains active.
• Save the confirmation and boarding pass where they work without a connection.
• Ask where checked baggage is being routed or held.
• Review the airline's current contract, customer-service plan, and fare terms.

Airline contracts and screening procedures change. Confirm the current rule with the operating airline, TSA, or U.S. DOT before flying.
