Delta Air Lines quality
Delta is a pretty good airline overall. I haven't flown on their A330 (or any A330) but most of their planes are nice. I've gotten a bit tired of flying ont heir MD-80s because I've flown on so many Delta and American MD-80s. I will fly on one of their A330s this summer (actually on a U.S. domestic route); hopefully it will be nice. I was particularly impressed by a meal I got traveling in economy class from LHR to ATL on a Delta 767. Penne pasta with alfredo sauce and spinach: quality that you'd expect on the ground, but served in the air!
