What happens if you miss your flight
Miss a flight without telling the airline and the rest of the ticket can be cancelled. What Delta and Lufthansa say in their own terms, and what to do first.
If you miss your flight and the airline does not hear from you first, you can lose more than that one seat. As of October 2026, Delta’s own policy says a customer who does not notify it before departure forfeits the value of the ticket, and Lufthansa’s conditions let it cancel your booking if you miss the gate. Contact the airline before departure if you possibly can.
At a glance
- Missing a flight without telling the airline is a no-show. The rest of the ticket, including a return, can be cancelled with it.
- Delta, as of October 2026: a no-show who has not notified Delta or a travel agent before departure forfeits the value of the ticket, and Delta may cancel every remaining flight in the itinerary (Domestic Contract of Carriage, Rule 14(C)).
- Lufthansa, as of October 2026: Article 6.3 lets it cancel your booking if you miss the gate, and Article 3.3.3 recalculates the fare for unused or out-of-order legs.
- If a delay or schedule change is the airline’s doing, different rules apply. Delta’s no-show policy does not apply to tickets hit by a qualifying delay or change.
- Neither airline’s terms quoted here promise a seat on the next flight.
- Flydar watches fares before you book. It does not track flight status, rebook you or warn you about delays.
What happens if you miss your flight?
Missing your flight usually turns your ticket into a no-show, and what you lose depends on the airline’s terms and on whether you contacted it first. Delta says the value of the ticket is forfeited if you do not notify it before departure. Lufthansa says it may cancel your booking if you fail to arrive at the gate in time.
Contact before departure keeps your options open. Silence puts the airline in charge of what happens to the rest of the trip.
What do the airlines’ own terms say?
Both airlines publish the rule. Here is what each says, quoted from their own documents (checked October 2026).
| Airline | Clause | What it says |
|---|---|---|
| Delta Air Lines | Domestic Contract of Carriage (last modified 18 August 2026), Rule 14(C): Failure To Appear | ”If you fail to appear for any flight in your itinerary without changing or canceling your ticket prior to departure, Delta may cancel your reservation for all remaining flights in your itinerary. Except where required by law, there will be no remaining value to your ticket.” |
| Delta Air Lines | No Show Policy page (updated 18 December 2025), which points to Rule 14(C) | “If a customer is a no-show and does not notify their travel agent or Delta of a change or cancellation prior to their departure, they will forfeit the value of their ticket.” Unused coupons “will eventually show a status of ‘SUSP’” and “have no further value.” |
| Lufthansa | General Conditions of Carriage for Passengers and Baggage (October 2025), Article 6.3 | ”We have the right to cancel your booking if you fail to arrive at the boarding gate in time.” |
| Lufthansa | Article 3.3.3 | If carriage “is not used on all individual legs or not used in the sequence specified on the ticket,” on a fixed-sequence fare Lufthansa will “recalculate the fare according to your amended routing.” Not applicable to passengers resident in Germany and Austria, who fall under Article 3.3.4. |
Delta’s policy page says it applies to refundable and non-refundable tickets alike, with refundable tickets covered if issued on or after 8 October 2025. It also covers both wholly unused and partially flown tickets.
Lufthansa’s Article 3.3.3 works differently from Delta’s. It does not say the return disappears. It says the fare is repriced for the route you actually flew, and Lufthansa may make carriage depend on you paying the difference. That can be higher or lower than what you paid. Read the fare conditions for your own ticket, because the clause only applies to fares that require a fixed ticket sequence.
Other airlines publish their own versions. Search your airline’s contract of carriage for “no-show” or “failure to appear” before the day of travel.
Which situation are you in?
The answer changes with why you missed the flight and what you missed.
| Situation | Likely outcome | What to do now |
|---|---|---|
| You were late and the flight left, one-way or first leg, no contact with the airline | No-show. Delta: ticket value forfeited. Lufthansa: may cancel the booking and reprice unused legs. | Contact the airline immediately; Delta’s page says an agent may still help while coupons are open. |
| You know you will miss it, hours before departure | Best case. Delta: notifying before departure is what keeps the ticket’s value. | Call or use the airline’s app now to change or cancel. |
| A late inbound flight on the same ticket made you miss the connection | Airline disruption, not your no-show. Delta: tickets hit by a delay of 180 or more minutes (domestic) or 360 or more minutes (international) are not subject to its No Show Policy. | Go to the airline’s desk at the airport; do not leave without a new itinerary. |
| You missed the first flight but plan to fly the return | Return may be cancelled with the outbound (Delta), or the fare may be repriced (Lufthansa Article 3.3.3). | Ask the airline before travel whether the return is still valid. |
| You missed a flight on a separate ticket | The second airline’s own no-show terms apply to that ticket. The first airline’s delay is a separate contract. | Contact the second airline at once; see self-transfer flights. |
Should you call the airline before departure?
Yes. The one fact worth remembering is that notifying the airline before departure is what separates a changed ticket from a forfeited one on Delta, as of October 2026.
Delta’s page says a customer who contacts the airline or a travel agent after the original departure may still be helped, but only “if the flight coupons are still open for use.” If the coupons are suspended, “the ticket has no remaining value.” The window is short, so the safest move is the earliest one.
Is there a “flat tire” rule that puts you on the next flight?
No. Neither the Delta policy nor the Lufthansa conditions quoted above promises a seat on the next flight. Any help an agent offers is discretionary.
If an agent offers a seat on the next flight, take it. If not, you have no clause to point to, so plan as though the ticket may be gone.
What if the airline caused the missed connection?
If a late first flight makes you miss a connection on the same ticket, you are not the one who failed to appear. Delta’s no-show policy says tickets “impacted by an Irregular Operations event or a Significant Schedule Change or Delay will not be subject to Delta’s No Show Policy.” For tickets issued on or after 28 October 2024 Delta defines that as an earlier departure or later arrival of 180 minutes or more on domestic itineraries or 360 minutes or more on international ones, plus changes such as a different airport, an added stop, a downgrade or a different operating carrier.
Two separate tickets put a missed connection on you. That trade-off is also why a round trip bought as two one-ways can cost you protection as well as save money. Check whether an itinerary is one ticket or several before you book.
Do you get taxes back on a missed flight?
It depends on the airline’s fare conditions. Lufthansa’s Article 10.1.3 says “the refund value of the fare, taxes and fees will be calculated according to the fare conditions and any segments of the ticket used.” Delta’s no-show policy speaks of the ticket’s value and does not break taxes out separately.
So ask, in writing, whether unused taxes and fees on the missed segments can be refunded, and keep the reply. If you booked within the last day, the 24-hour cancellation rule is a separate route, but it does not cover a flight you simply did not take later.
Where Flydar fits
Flydar does not rebook you, track flight status or warn you about delays. It watches the fare on a route you set and emails you when it drops clearly below what that route normally costs. The link to this topic is small: a cheap ticket is only cheap if it is the right kind of ticket, and a replacement fare bought in a hurry after a missed flight is rarely a good one. See Flydar’s pricing if you want the alert side of that.
For tools that track a flight, see how to check flight status.
What to do in the next 30 minutes
- Do not walk away from the desk or end the call until you know what is still valid.
- Contact the airline by app, phone or desk. Say “I missed my flight” and ask whether your return, onward or next leg is still valid.
- Ask about a change or standby, and what it costs, before agreeing.
- If a delay on the airline’s side caused it, say so and ask for the disruption to be noted on the booking.
- If it was a separate ticket, contact the second airline now, not after it has left.
- Ask in writing about refunds of taxes and fees on the unused segments and keep the reply.
- Note your booking reference, call time and the agent’s name.
If the answer is “you are a no-show”, ask one more question: what, exactly, is still valid?

Common questions
- What happens if you miss your flight?
- It depends on whether you told the airline first. As of October 2026, Delta's own policy says a customer who does not notify Delta before departure forfeits the value of the ticket, and unused coupons are marked as having no further value. Lufthansa's conditions let it cancel your booking if you miss the gate. Contact the airline before departure if you can.
- Does missing the first flight cancel my return flight?
- Often, yes. Airlines treat an unused first segment as a no-show and may cancel the rest of the itinerary. Delta's policy says unused coupons end up with no further value, and Lufthansa's Article 3.3.3 says unused or out-of-sequence legs on a fixed-sequence fare trigger a fare recalculation. Check your fare rules before skipping any leg.
- Can I get a refund if I miss my flight?
- Usually not for the fare. Delta says a no-show forfeits the ticket's value, including refundable tickets issued on or after 8 October 2025. Lufthansa's Article 10.1.3 says the refund of fare, taxes and fees follows the fare conditions and the segments used. Taxes may be a separate question, so ask the airline in writing.
- What if I miss my flight because the first flight was late?
- On a single ticket, a late first flight is the airline's disruption, not a no-show by you. Delta's policy says tickets hit by a delay of 180 minutes or more (domestic) or 360 minutes or more (international), among other triggers, are not subject to its No Show Policy. Go to the airline's desk at once; do not just leave.
- Should I call the airline if I know I will miss my flight?
- Yes, before departure if at all possible. Delta's policy puts the line at notifying the airline or your travel agent prior to departure to keep the ticket's value. Even after departure, Delta says a travel agent may still help while the flight coupons are open, so move quickly rather than assume the ticket is gone.
- Is there a legal right to be put on the next flight if I am late?
- Not in the Delta policy or Lufthansa conditions quoted here. Both describe consequences for missing a flight, and neither promises a seat on the next one. Any agent help is discretionary and varies by fare, airline and how full the next flight is. Treat it as a favour, not a right.
