US Airways and American Airlines are expected to reveal their post-merger senior management team within the next 2-3 weeks, says American CEO Tom Horton.

The carriers have already announced board membership structure for their proposed merged airline, and have said that US Airways head Doug Parker will be CEO and Horton will initially be non-executive chairman. By mid-June, the carriers will release the next tier of upper management, Horton told Aviation Week on the sidelines of the International Air Transport Association (IATA) annual general meeting in Cape Town.

The airlines will announce the management team level by level, says Horton. The senior vice president/executive vice president positions will be revealed first, followed by the next tier of vice presidents.

Horton says the merger process is “moving well,” with transition teams working on integration planning so the carriers will be ready to act when the approval process is completed.

Some experts believe U.S. regulators will consider requiring slot divestitures at Washington Reagan National Airport, but Horton stresses that there is no need for such requirements. “We don’t think there is any rationale for divestiture at DCA,” Horton says. He notes that competition at the airport is “very robust.” A coalition of lawmakers has written to regulators opposing any divestitures, as they would likely affect smaller communities.
