MIAMI — United Airlines is insourcing at some of its stations while outsourcing others following station reviews, according to sources. More than a dozen stations were reviewed and bids were taken to determine which route each would take, part of cost-cutting measures. Now the results are in.

In April, United discussed plans to outsource jobs at the Lihue, Kona, and Kahului airports in Hawaii. However, the carrier has since decided to reverse course. Further complicating the matter, the employees at these stations still need to approve the contract due to different wages and work rules. This vote is expected later this month.

United has also determined that it will insource all of its above wing jobs at Honolulu, as well as United Express operations in Phoenix and Washington Dulles. Plus, it will bring back all of its jobs it outsourced in Denver a few years ago to in-house.

However, the story is different at a dozen other stations across United’s network. The carrier will outsource all of its operations in Albuquerque, Buffalo, Charleston (South Carolina), Charlotte, Columbus, Des Moines, Detroit, El Paso, Pensacola, Salt Lake City (ramp only), Sioux Falls, and Wichita.

“This is a difficult decision, but we need to ensure that our costs are competitive,” said United spokesperson Christen David.

In total, the airline will gain approximately 400 new jobs, but with the outsourcing, over 600 jobs will be lost.

The transitions are expected to occur around October 1st.
