I think this information is incorrect. We are flying AA 2203 DFW-SEA later this week in F. According to the configuration of the first class cabin (seats 6AB directly across aisle from 6EF), this is an ex-TWA. SEA-DFW last week was 2302 (?) with 6EF across the aisle from a closet. It had power ports.
I guess the success of actually finding information on aa.com is somewhat negated by the fact that the information was wrong.
PS. On further thought, I guess the designation of flight numbers 280-2999 as ex-TWA could be correct but incomplete. Bottom line: I will know whether our flight has power ports when we board.
