It might seem like a semantic distinction: your flight didn't operate as planned, so what does it matter whether it is called a delay or a cancellation? Under EC261, the difference is more than academic. Delays and cancellations trigger different rights, different compensation thresholds, and different obligations for the airline. Airlines are aware of this, and they sometimes frame a disruption in whichever way minimises their financial exposure.
The legal difference
A delay means your original flight still operates, but later than scheduled. The aircraft, the flight number, and the route remain the same; the departure is simply pushed back. A cancellation means the original flight ceases to exist. The airline withdraws the service entirely and may offer an alternative flight, but that alternative is a different operation.
The distinction matters for several reasons. With a cancellation, you have an immediate right to choose between a full refund and rebooking, a right that does not automatically exist for delays. With a cancellation, the 14-day notice period is relevant: if the airline notified you more than two weeks before departure, no compensation is owed regardless of the reason. With a delay, the only threshold is the 3-hour arrival rule.
How airlines blur the line
A flight that is delayed by 18 hours and moved to the next day: is that a delay or a cancellation? The airline may argue it is just a long delay (to avoid the refund obligation). You may argue it is effectively a cancellation (to access the refund right). Courts have generally held that if the flight number changes, the aircraft changes, and the schedule is fundamentally different from the original, this is a cancellation regardless of what the airline calls it.
Another common scenario is schedule changes. An airline may change a 9am departure to a 4pm departure and call it a "schedule change" rather than a cancellation. If this change significantly alters your travel plans, it may legally constitute a cancellation for EC261 purposes.
| Delay | Cancellation |
|---|---|
Same flight number, same aircraft, later departure |
Flight withdrawn, new service offered |
Compensation if 3+ hours late at arrival |
Compensation if <14 days notice (subject to rebooking windows) |
No automatic refund right |
Choice of full refund or rebooking |
Right to care during wait |
Right to care until refund or rebooking |
Why it matters for your claim
In most straightforward cases, the classification does not change the compensation amount. €250, €400, or €600 applies equally to delays and cancellations based on distance. But it can affect your strategic options. If your flight is cancelled, you can choose a refund and walk away, useful if the disruption means the trip no longer makes sense. If it is classified as a delay, you do not have that automatic right and may be stuck waiting.
The classification can also affect the airline's defence. For cancellations, the 14-day notice period provides a complete exemption if the airline informed you early enough. For delays, no such exemption exists — the only question is whether you arrived more than three hours late.
What to do if you are unsure
If your flight situation feels like it falls between a delay and a cancellation, document everything carefully. Note the original flight number, the scheduled times, what the airline communicated, and the details of any replacement flight offered. If the airline tries to classify the disruption in a way that reduces your rights, you can challenge this classification. Courts have shown a willingness to look at the substance of what happened, not just the label the airline applies.
