How to Read a Delay Before the Airline Explains It
Aircraft position, crew timing and weather tell you more than the departure board does.
Read GuideThe label on the board changes your options, your entitlements and your next move.

Rules change without notice. Confirm anything time-critical with the airline, airport or border authority handling your journey before you travel. Read our fact checking policy.
A cancellation removes the flight and normally triggers rebooking or refund rights; a delay does not.
Watch for aircraft assignment as the strongest delay signal.
Ask for rebooking options as soon as a cancellation appears.
Record the reason the airline gives, word for word.
A delay and a cancellation feel similar when you are standing in the terminal, but they trigger completely different obligations and completely different actions on your part.
The practical difference is this: a delay leaves your ticket intact and the airline still intends to operate the flight. A cancellation removes the flight from the schedule and hands you a right to be rerouted or refunded.
Knowing which one you are actually facing, and how the status can quietly change between them, is what determines whether you are home tonight or sleeping near the airport.
| Delay | Cancellation | |
|---|---|---|
| Flight still in schedule | Yes | No |
| Your ticket | Unchanged | Must be reissued or refunded |
| Choice of refund | Only after long delays in some regions | Yes, in the EU and UK |
| Rerouting duty | Limited | Yes, at the earliest opportunity |
| Care duty (meals, hotel) | Yes, after set thresholds | Yes, immediately |
Under EU Regulation 261/2004 and the equivalent UK rules, care obligations begin at two hours of delay on short flights, three hours on medium and four on long-haul, whatever the cause. Compensation is a separate question and depends on the reason.
Care and compensation are different things
Care means meals, communication and a hotel where needed, and it is owed regardless of fault. Compensation is a cash payment and is not owed when the cause is genuinely extraordinary, such as severe weather or air traffic control restrictions.
The most damaging pattern is the delay that grows in small steps. Thirty minutes becomes an hour, then two, then the flight is cancelled at eleven at night when every hotel near the airport is full.
Airlines are not being deceptive when they do this. Each update reflects the latest estimate for a crew or aircraft that is itself running late elsewhere. But the effect on passengers is that nobody makes a decision until it is too late to make a good one.
A rolling delay at Amsterdam Schiphol
An evening KLM departure to Madrid was posted at 30 minutes late at 18:40, an hour late at 19:20, and cancelled at 21:15. Passengers who joined the rebooking queue at 19:30, while it was still just a delay, were mostly on the 07:00 flight the next morning. Those who waited for the cancellation were on the 14:00.
Act on the second update, not the third
When a delay is revised upwards twice, treat it as a probable cancellation and start protecting yourself immediately, even while the board still says delayed.

Accepting a voucher can end your claim
If you accept a travel credit as settlement rather than a rerouting or refund, you may waive the right to a cash refund. Read what you are agreeing to before tapping accept.
During any large disruption, use two channels at once. Stand in the physical queue while working the app or phone line, and take whichever produces an answer first.
Phone lines in other countries are often quieter. If your carrier has a local number in a market with a different time zone, that queue may be a fraction of the length.

In the EU and UK, cash compensation of 250 to 600 euros applies when you arrive three or more hours late, the airline is responsible for the cause, and the flight either departs from the region or is operated by a regional carrier arriving into it.
| Distance | Arrival delay | Compensation |
|---|---|---|
| Up to 1,500 km | 3 hours or more | 250 EUR |
| 1,500 to 3,500 km | 3 hours or more | 400 EUR |
| Over 3,500 km | 4 hours or more | 600 EUR |
The clock that matters is arrival, not departure. A flight that leaves two hours late but arrives three and a half hours late still qualifies, which is why keeping a record of the actual arrival time matters.
Cancellation with short notice
A cancellation notified less than 14 days before departure can also attract compensation, unless the airline offers a rerouting within tight time limits around your original schedule.
Ask for the reason in writing
One sentence from the airline stating the cause is the single most useful document in any later claim. Ask at the desk while staff are still available.
A delay leaves your ticket in place, a cancellation replaces it with a right to rerouting or a refund. The two demand different actions.
Rolling delays are the real danger. Two upward revisions is the point to start rebooking, not the point to keep waiting.
Use two channels at once, queue and phone or app, and ask for specific alternative flights by number including partner airlines.
Care obligations apply regardless of cause; compensation only when the airline is responsible and you arrive three or more hours late. Keep the receipts and get the reason in writing.
