Definitas

I remember seeing a thread along these lines a while ago but cant find it. Can anyone provide an objective view of AA Premium Economy and, if possible, compare it to BA and/or VA (I have flown the latter two). BA are offering some decent codeshare prices for daytime PE flights to/from ORD on AA in early summer. The aircraft is listed as a 787-8 but I have read that they will all be reconfigured with the new 2-3-2 PE by then. I am vertically challenged so not too worried about legroom but would like to know how the food/beverage service is and what the cabin service is like. Also, for someone with no OW status, does AA offer a PE check in?

Thanks for any tips
