Sorry, I know this is not argumentative and therefore not 'interesting' but on a 'day in day out basis' it has to be BA. I remember a few years ago a diverted flight to Montreal rather than Toronto [fog] and the crew were brillant especially the guys at the 'sharp end' who tok the time to describe all the issues and explain why we were going to be 24 hours late!
The interesting point is that when we did finally arrive at our destination, none of the pax had a word of complaint, thanks to the work of all the BA staff inolved. So forget all the nonsense about 'hot' f.a. [How 70s is that?] Who would you want to be flying with when things go awry.
