[2] Around this same time, several aircraft received experimental paint schemes with different striping and tail designs, though none were ultimately adopted fleet-wide.
[3] In the late 1980s, at the time of Piedmont Airlines being acquired, the company changed its colors to red, white, and blue.
The livery adopted under this scheme continued to utilize a primarily unpainted plane, instead with a thick red cheatline, topped by a narrower blue one.
After the 2005 merger of US Airways and America West Airlines, an off-white livery[8] was chosen to better meet operational needs due to the summer heat at the Phoenix Sky Harbor International Airport and Las Vegas McCarran International Airport hubs inherited from America West.
The first jet to re-enter revenue service was an Airbus A319, tail number N700UW, which previously sported a Star Alliance branding.
[10] The post-merger US Airways continued the America West tradition of logo jets and only used Airbus A319 aircraft for these special liveries.
[26] The Allegheny heritage plane[27] was given a more accurate grey underbelly, a more appropriately sized running strip, and the registration was moved above the window line.
