American Airlines and US Airways passengers can now access both the US Airways and American Airlines terminals without leaving security via new shuttle service with stops at Gate 39 in Terminal 3 and at Gate 44 in Terminal 4.

Terminal 3 will not have a US Airways Club lounge, forcing passengers to access the AA lounge in the neighboring terminal.
