Y seats on United SUCK! ('coz of the legroom)
I though Lufthansa's and Air Malta's were quite good. (pitch and comfort wise)
I also like the old SAA 747's which had 34" pitch in Y class - very roomy
's economy seats are really comfy but their legroom is a little stingey!
As for J Class: I'd have to go with the NEW SQ
beds! (or even CX
for that matter)
