Strike cancelled flight. Rules are confusing, here goes:

Why this happens more than you'd think
Flights break for a hundred reasons - crew timing out, a tech fault on a previous leg, slot restrictions, weather upstream. The airline's first move is almost always to reshuffle aircraft and crew, not to babysit passengers. That's why being polite but persistent at the desk gets you further than waiting for an email. The earlier you ask, the better the seats left on alternative flights. Once a wave of cancellations hits, the next 90 minutes decide who flies tonight and who sleeps near gate B14.
Do this right now

- 2Rebook fast before everyone else does.
What you're entitled to

Two channels at the same time
Open the airline app and the airline's chat in your browser, then start the line at the desk. Whichever moves first, you take. People lose hours by picking just one. Also, screenshot every status change - timestamps matter when you claim later. If the staff hand you a paper voucher, photograph both sides before it lives in your pocket.
Quick fixes that work
What to say at the desk
"Per CJEU rulings (C-195/17 and others), an airline staff strike does not qualify as extraordinary. I am claiming EU 261 compensation."
Small things that make a big difference
- Take a photo of the departure board the moment you see the cancellation - it's your timestamped proof.
- If your flight is operated by a partner airline (codeshare), call the operating airline, not the marketing one.
- Politeness gets you further than shouting. Agents have discretion - use it.
- Keep every receipt for food, taxi, hotel - even small ones. They add up at claim time.
- Don't sign anything that says 'final settlement' until you've checked your full entitlement.
What 'extraordinary circumstances' really means
Airlines love this phrase because it removes their compensation duty. But it does NOT remove your right to a refund, to be rerouted, or to meals and a hotel during the wait. Don't let one word from a tired agent end the conversation. If you hear it, ask for the reason in writing - that single line on letterhead is what your insurer or the regulator will need.
