Exhibit 99.1

FOR IMMEDIATE RELEASE

US AIRWAYS REPORTS RECORD FEBRUARY LOAD FACTOR

TEMPE, Ariz. Mar. 4, 2013 — US Airways Group, Inc. (NYSE: LCC) today announced February and year-to-date 2013 traffic results. Mainline revenue passenger miles (RPMs) for the month were 4.4 billion, up 2.2 percent versus February 2012. Mainline capacity was 5.5 billion available seat miles (ASMs), down 1.2 percent versus February 2012. Mainline passenger load factor was a record 81.0 percent for the month of February, up 2.7 points versus February 2012.

US Airways’ President Scott Kirby said, “Our February consolidated (mainline and Express) passenger revenue per available seat mile (PRASM) increased approximately one percent versus the same period last year. Our 32,000 employees continued to deliver outstanding operational results as we produced record load factors and we thank them for their hard work.”

The Company estimates that its unit revenue performance over the President’s Day holiday travel period was negatively impacted by approximately four percentage points, which it believes is partially attributable to the lingering effects of Hurricane Sandy as many schools in the Northeast remained in session during the holiday break.

For the month of February, US Airways’ preliminary on-time performance as reported to the U.S. Department of Transportation was 82.0 percent with a completion factor of 98.3 percent.

The following summarizes US Airways Group’s traffic results for the month and year-to-date ended February 28, 2013 and February 29, 2012, consisting of mainline-operated flights as well as US Airways Express flights operated by wholly owned subsidiaries PSA Airlines and Piedmont Airlines.
