U.S. Airways will embark on it's final flight this morning.
Flight 1939 is scheduled to depart Philadelphia International Airport at 10:05 a.m., stop in Charlotte, NC; Phoenix, AZ before landing in San Francisco.
When the airbus 321 returns to Philadelphia on Saturday it will be wrapped in an American Airlines banner.
This is the result of the 2013 mega merger with American Airlines.
U.S. Airways operated nearly 7,000 flights daily, had more than 100,000 employees and managed about eight percent of all U.S. domestic flights.
The airline started in Pittsburgh, PA in 1939 and was called All American Aviation.
U.S. Airways pulled out of Pittsburgh in the early 2000s.
Currently the airline has hubs in at Philadelphia International Airport in Philadelphia, PA; Charlotte, NC and Phoenix, AZ; but will be headquartered in Fort Worth, Texas under American Airlines.
According to American Airlines they will keep U.S. Airways' three hubs operating for at least five years.
