Could AA fit in US side of Terminal B as things stand now? AA and US have cut so much capacity I cant imagine they would need very many gates.
Massport says that United/Continental will use Terminal B, Pier A when the construction is completed. AA will be in Pier A as well, but has given up 4 gates + 4 Eagle RJ gates (Section 1.2):
