<P> With the exception of flights from destinations with U.S. Customs and Border Protection preclearance , all inbound international flights arrive at Terminal 5 , as the other terminals do not have screening facilities . Several carriers , such as American , Iberia , Lufthansa and United , with outbound international flights depart from Terminals 1 and 3 . This arrangement requires that passengers disembark at Terminal 5 and then , crews tow the empty plane to another terminal for boarding . This is done , in part to make connections for passengers transferring from domestic flights to international flights easier , since while Terminals 1 , 2 , and 3 allow airside connections , Terminal 5 is separated from the other terminals by a set of taxiways that cross over the airport 's access road , requiring passengers to exit security , ride the Airport Transit System , then reclear security in either direction . </P>
