Major airline tenants at O'Hare International Airport are gearing up for the largest reshuffling of gates in decades, the Tribune has learned.
Passengers of Delta Air Lines Inc. and Continental Airlines would face the greatest dislocation if plans being discussed by carriers and the City of Chicago come to fruition.
Delta is expected to leave its longtime base at the far end of Terminal 3 and move to merger partner Northwest Airlines' gates in the middle domestic terminal, said people familiar with its plans. Delta also is expected to take over four gates that Continental subleases from Northwest at Terminal 2, sources said.
Continental, meanwhile, is in talks to move into Concourse B at United Airlines' home hub.

Continental would keep its ticket counter and baggage operations in Terminal 2, Brady added.

Continental would be the first major U.S. rival to operate flights from United's Helmut Jahn-designed terminal. Aside from United, the only airlines using the terminal are international carriers like Lufthansa that, like United, belong to the Star Alliance.
Continental plans to join Star in October and is in the process of withdrawing from the SkyTeam alliance, which includes Delta and Air France-KLM.
A person familiar with talks between United and Continental cautions that their plans for O'Hare aren't final. Continental could remain in Terminal 2 by taking over three gates on Concourse F that it subleases to United.
