Careful on the AA 787 and 777. The PHL flight might be a 787-800, in which case the seats are likely to be Zodiac alternative facing seats that are not as good as normal herringbone. If it's a 787-900, you're good. On the 772, there's a reasonable shot at getting the bad seats too, although <50%.

They're probably all better than old CW though.
