I am inquiring between United and Delta. Which coach product would you prefer between these two and why? Which has more room for someone who is 6 feet and 270? I don't fly often but am going to start going to see family in Tenessee as most of you will remember and my dad told me for people my size delta's coach product is pretty bad, and I know AA's is nice, but am curious which YOU personally like better and why if you don't mind sharing? Also, which do you find easier to redeem award tickets on, as almost all tickets will be purchased using pts earned from a CC. Thanks in advance!
