US Airways has moved its operations at Las Vegas McCarran International airport to concourse D, after 30 years in concourses A and B.
The Tempe, Arizona-based Star Alliance member will use six gates on concourse D, according to an employee newsletter. It used four gates on concourse A.
US Airways says that the move is to be closer to its codeshare partners, which include United Airlines. However, it also puts it closer to its planned merger partner American Airlines.
The decision to move was made before it announced plans to merge with American in February, the carrier adds.
Concourses A and B were once home to US Airways' former Las Vegas hub, which it inherited from America West Airlines when the carriers merged in 2005.
The airline began cutting flights at its Las Vegas hub in 2008. It handled about 140 flights per day at its peak.
The carrier flies to Charlotte, Philadelphia, Phoenix and Washington National from Las Vegas with about 19 flights per day.
America West began service to Las Vegas in 1983.
