CHICAGO (AP) — The CEOs of United Airlines and US Airways have told their employees that a combination of the two carriers won't happen "at this time."

Their messages came a day after a meeting at which United disclosed to the smaller carrier its decision not to pursue a deal.

UAL's Glenn Tilton says he still supports mergers but the airline decided this one wouldn't work for now because of issues that could significantly dilute the benefits.

Doug Parker of US Airways also told his employees that he wouldn't preclude something occurring in the future.

Chicago-based United and Tempe, Ariz.-based US Airways have been exploring a combination for more than two months. But labor and financing issues clouded the effort.
