HOW STRONG IS THIS CLAIM?
Possible claim — mixed factors
Decent case — worth filing; expect one round of pushback.
- ✓The flight was cancelled. With less than 14 days notice and no timely re-routing, cancellations are strong claims.
- ⚠There were adverse weather conditions around this flight, which an airline may point to — though moderate weather alone rarely qualifies as extraordinary.
- ⚠We could not fully verify the actual arrival time, so confidence is reduced.
✓ WHY IT MAY QUALIFY
Cancellation (Article 5). With under 14 days’ notice — and a same-day cancellation is by definition under 14 — compensation is owed unless the airline proves extraordinary circumstances.
Covered by EC261; the distance (1,564 km) sets the band: up to €400 per passenger.

More on the defence: what counts as extraordinary circumstances, and what doesn’t.
Why was BA503 cancelled?
- Airlines don’t publish the cause, and we don’t know it for this flight.
- The weather record: LIS: Rain, Overcast · 16°C · wind 27 km/h, gusts 58 · 12.1 mm rain · LHR: Overcast · 8°C · wind 16 km/h, gusts 35 · 0.4 mm rain.
- Our radar recorded no other cancellations at Lisbon that day.
To refuse compensation, the airline has to prove the cause was an extraordinary circumstance that could not have been avoided even if all reasonable measures had been taken (EC261 Article 5(3)).
Technical faults almost never count, and neither does a strike by the airline’s own staff. The EU’s top court has ruled on both (C-549/07, C-28/20).
Severe weather and air traffic control limits can count, but the airline must show they caused this flight’s disruption.
Weather can excuse compensation, never care: meals, hotel, and rebooking are owed regardless of cause.
