US Airways just made its final flight before becoming American Airlines

Over the weekend, US Airways ceased independent operations after more than 75 years in business. Flight 1939 - the final flight operated using the US Airways name - started at the airline's Philadelphia hub before flying to Charlotte, Phoenix, San Francisco and Philadelphia.

After its final flight, the Tempe, Arizona-based airline combined its flight and ticketing operations with its merger partner, American Airlines.

This is the culmination of an $11 billion merger that was first announced in 2013. Prior to the merger, US Airways boasted a fleet of more than 300 jets. The post-merger American Airlines now has the largest fleet in the world, with more than 900 mainline aircraft.

"US Airways Flight 1939 was the final US Airways flight to take off - ever," An American Airlines spokesperson told Business Insider in an emailed statement. "It was named in honor of the year that US Airways started flying 76 years ago as a mail carrier."
