I usually fly economy and I really can't remember a bad experience with the meals served. And, to the surprise of some of you, the best meal I've ever had in a plane was aboard an United Airlines 767-300 flight from GRU
. A so rich breakfast that consisted in breads, an omelet, a sandwich, fruits, a cake and a nice variety of beverages available.
Tam's and AA
's food are very good as well, although the American portions are usually too small.
Even with the low cost GOL I had a good sandwich (but cold) with a little cake.
I usually like very much airplane food!
