When an airline tells you that your flight was disrupted because a pilot fell ill or the crew exceeded their legal working hours, it can sound like a reasonable, unavoidable situation. After all, you would not want to fly with an unwell pilot. But the legal question under EC261 is not whether the airline's response was appropriate — it is whether the underlying event was extraordinary. Courts have consistently found that crew problems are not (see our guide to extraordinary circumstances).
Why crew issues are not extraordinary
Airlines employ thousands of crew members who fly millions of hours each year. Illness, fatigue, and scheduling conflicts are statistically inevitable facts of running an airline. A well-managed carrier plans for these events by maintaining standby crews at major bases, building buffer time into schedules, and having procedures for rapid crew substitution. When the system fails despite these measures — or worse, when no such measures are in place — that is an operational failure, not an extraordinary event.
The European courts have been clear on this point. Crew illness is a foreseeable part of airline operations. The airline's obligation is to have contingency plans, not to pretend that human beings never get sick.
Common crew-related excuses
- Pilot or cabin crew called in sick — airlines should have standby crew
- Crew exceeded maximum working hours (timed out) — results from scheduling or prior delays
- Crew not available due to previous delay — operational knock-on, not extraordinary
- Insufficient crew for the aircraft type — staffing and roster management failure
- Crew refused to fly for safety reasons — internal operational matter
The standby crew argument
Airlines are expected to have standby pilots and cabin crew available at their main operating bases. The exact number of standby crew varies by airline and base, but the principle is clear: an airline that operates dozens of daily flights from a hub and has no standby crew available is failing in its operational planning. When the absence of standby crew leads to a cancellation or long delay, the responsibility lies with the airline.
How to respond if the airline cites crew issues
State clearly that crew illness, scheduling problems, and working-hour limitations are not extraordinary circumstances under EC261 case law. Note that the airline has an obligation to maintain adequate crew reserves and contingency plans. Ask them what reasonable measures they took to mitigate the disruption. For example, did they attempt to source a replacement crew from another base? If their response is unsatisfactory, escalate to the relevant national enforcement body.
