"Brit Air is good."

BA is good, although the seats seem to lack an inch or two front to back space than other airlines.
Virgin Atlantic is also exemplary.
Aer Lingus is better than either. The staff has sense and is free to use it.
Duds and drags unmentioned.

It's the airport searches which are the choke points. Unfortunately ships don't do it these days.

(Experiences within the last 8 months.)

I have flown Virgin before and it was pretty darned good (clean, airy cabin, friendly staff). My contract allowed me Premium Economy and it was pretty nice, though Business Class is even better, and I agree with you, Brit Air seems a bit small, and in Economy some of the seats actually ARE smaller if they are near the back or are bulkhead. I was in the UK and BBC did a report on seat sizes and found this to be true.
Nice to be in the front of the jet, as not only are the seats bigger and more comfortable, I find the staff to be nicer. . .either UK air carriers or US.
I probably should look into Aer Lingus, but have several hundred thousand miles on Brit Air and kinda got used to them.
Will be flying Brit Air again within two moths and will let you know.
Though, Brit Air "limits" the weight of your carry on to 11 kilo's for Business (9 for economy). This is enforced in London but not outbound flights from the US. I loath to check luggage and pack smart, so this usually doesn't cause any problems when in Business, but I don't like the fact that they established different weights for different classes of travel, for the same sized bag.
Anyway, thanks for your comments.
