I'd do DL if price is equal. I'm a longtime AA flier and generally a fan, but I wouldn't pay a lot of money for their domestic F product.

- Seatguru, at least for now, thinks LAX-MCO is the international config. (Lie-flat seat.) That gives it a huge advantage over AA on that segment.

- If Seatguru is wrong, then it's a push: both airlines are in the 38-40" range with regular F seats. I flew the AA 737-800 in F yesterday, 2 segments, and I noticed the thin cushion. I suspect DL has a more comfortable seat.

- The AA 737 has a seatback video screen, although I didn't use mine yesterday so no idea what content is there. (Large screen though...probably HD-quality.) On your redeye taking off at 10PM PT, do you plan to watch a movie or try to get some sleep?

- AA was 0 for 2 yesterday on PDBs. On one segment, they didn't even come and collect jackets until the whole plane had boarded. On the plus side, I actually liked my meal, although it was a grilled chicken salad that I would hope most airlines would get right. You can reserve your meal online in advance, although I don't know what they do food-wise on redeyes departing well after the dinner hour.

- AA A319's always feel cramped to me. This is an old US Airways plane, I think.
