I need to find out the registration of this American 752 so I can upload it here. It's already been rejected because the registration is apparently 'easy to look up' but I haven't had any luck finding it.
The photo was taken at BOS at 0730 on 21 April and the 757 was about to depart runway 9.
The only other clues I have are the extra oneworld alliance logo next to the door and that the code on the nose gear doors looks like it might begin with 5F...
I hope someone can help since I'd really like to add this shot to my collection on A.net!
