UA moving to terminal B with AA.
Currently, the gates at Terminal B are not connected to one another behind security. The renovations will allow passengers to go from the United and American side of the terminal to the US Airways side without having to go through security a second time. The project will also give passengers using the two gates currently used by Virgin America access to the food court and concessions in the terminal.
