ExXB,
Yes, but when they telephoned me the day before that it was cancelled due technical I questioned "So there's not a spare aeroplane to the entire BA fleet to operate this service?" ... The BA liar on the other end of the phone replied "no".
I then asked if they had tried sub-chartering an aircraft in to operate the service, the BA liar replied to the effect that they had, I told him to give me an hour or so and I'd source them an aircraft to operate the service ... It was as clear as day that BA were lying and invol rerouted on a Luxair B737 to LHR with just a handful of pax on it provided the evidence.
So, yes, BA might have had a technical ATR in their fleet but my flight became cancelled for commercial reasons.
