I was traveling from LCY to MAN this evening but unfortunately the flight was cancelled along with others to GLA and EDI. Some flights did manage to take off.

The reason given was the the fog which closed in tonight and I know that this would normally preclude an EC261 claim from being made but unlike the other flights we were actually called to the gate and there was an E190 parked outside with the lights on!

In the end after half an hour the flight to MAN was notified as cancelled and suddenly the gate became the one for the flight to RTM.

Am I right to assume that if the flight destination was changed from MAN to RTM by BA then that would suggest that the decision to cancel the flight was not really due to the weather but - probably - priorisation for whatever reason to send the plane to RTM not MAN and that an EC261 claim could be made?

That said, I don’t know if the RTM flight (or the later BA ones still scheduled for GLA, DUB and EDI took off or not) did actually fly or not.

Is there anyway I can find that out?

Any thoughts or advice very welcome!
