Favourite Airlines
UK domestic:BMI
USA Domestic: JetBlue and Alaskan
International: Virgin Atlantic
International: Air NewZealand
For long haul travel, Air New Zealand are exceptional. In economy more legroom than most. The premium economy is better than most, and they have the same flat beds as Virgin in club/business/upper.
I like JetBlue because of the legroom in economy, and the staff are usually pretty good.
Alaskan have never failed to provide exceptionally good cabin staff.
Virgin Atlantic is not as good as it used to be, but across the atlantic they are probably better than BA. I previously favoured premium economy on Virgin over BA, but sadly the new prem seats have really reduced the legroom, so BA might win on that score. Sad to say, the last time I flew prem econ with BA, the cabin crew out and back just couldn't give a sh*t, and pulled faces every time a pax happened to ask for something unusual. You get good crews and bad crews, but BA over the last year and a half have really gone downhill.
That's just my opinion.
