I'm working on an itinerary, and aa.com allows me to book this connection, the first flight being on US, the second on AB:


1) Is this even doable? (both flights are at JFK T8)
2) If I make it, will my luggage make it?
3) If I don't make it, will they rebook me on the next AA flight through LHR, or will I have to wait a day for the next AirBerlin flight?

Also, has anyone flown US domestic first yet? Is it comparable to AA first (say, on a 737)?

Many thanks for your advise!
