In the second quarter of 2005, America West entered merger negotiations with then-bankrupt US Airways. It was structured as a purchase of US Airways by [[America West Holdings]]; however, the internal structure was a [[reverse merger]], with legacy US Airways operations taken over by those of America West.

As the holding companies merged, brand conversion began. The America West Club was renamed the US Airways Club in October 2005. All-new America West aircraft were delivered in the [[US Airways livery#Current Livery|new US Airways livery]], and older aircraft repainted (while retaining America West interiors). Gates and ticket counters were consolidated at airports where both airlines had operated, aided by the March 2007 transfer of all US Airways reservations to the Shares computer system used by America West (US Airways had previously used a very different  [[Sabre (computer system)|Sabre]] system).

All express flights were branded as US Airways Express and aircraft were no longer confined to operations out of their pre-merger hubs (America West aircraft could fly from Philadelphia to cities other than Phoenix and Las Vegas, for example). The two airlines' operating certificates were merged on September 25, 2007. After initially using the "CACTUS" callsign for the west fleet and "USAIR" for the east fleet, all aircraft began flying under a single "CACTUS" callsign and ICAO code "AWE" in September 2008. Meanwhile, US Airways abandoned Las Vegas as its hub. Former America West aircraft were distinguished apart from US Airways pre-merger aircraft by their use of registrations ending in "-AW", while pre-merger US Airways aircraft used registrations ending in "-US". US Airways would later merge with [[American Airlines]] in 2013, with the former America West callsign and ICAO code retired in 2015 (alongside with the US Airways brand). America West's Phoenix hub has remained intact with American Airlines.
