I would strongly suggest that for a 5 1/2 hour flight, you might want to pay extra to get American's Main Cabin Extra, or Delta's Comfort Plus seats, for the extra legroom. On a flight that long it will be worth it.

Many people will tell you Delta has a better "soft" product these days, but it is not that big a deal, if at all, on this flight. And you might want to get (and use) an American Airlines credit card through Barclays or Citi (whichever has the better sign up bonus) to get a free checked bag. If you fly Delta, they have a similar deal with Amex.
