United and Continental pair up

CHICAGO, June 19 (UPI) -- Continental Airlines and United Airlines announced plans to work together in a step analysts said could lead to a merger of the U.S. carriers in the future.

Continental, a member of the SkyTeam alliance, will switch allegiance and join United's Star Alliance, a statement said Thursday.

The cooperative move means the airlines will merge their computer systems, making it easier for passengers to make connecting flights.

The agreement also calls for "significant cooperation on frequent flier programs, lounges, facility information, technology and procurement."

"The teams worked well together to identify opportunities to create a unique and competitive partnership," United President, Chairman and Chief Executive Officer Glenn Tilton said in the statement.

Continental Chairman and CEO Larry Kellner said the arrangement has "significant value … as we experience some of the most challenging conditions airlines have ever faced."
