Operational reasons could cover anything, I had a call from BA some years ago, the day before the flight, to say they were cancelling for technical reasons.
'Bullsh1t' I told them, you've got 24 hours to source a replacement aircraft, they didn't and having been rebooked on an alternative carrier, whereas the minimal load of 2 combined flights clearly indicated the, so called, 'technical' reason, and my suitcase having arrived in a absolutely destroyed condition BA told me it was that other carrier's problem, despite travelling on a BA ticket, and the other carrier having no representation in UK.
When I questioned of BA who on god's earth decided they were the world's favourite airline they got the hump.
R.I.P. British Airways and the sooner the better, 7 years later they still haven't recompensed me for that suitcase so they can go to hell as far as I'm concerned
