US Airways Flight 1939 will leave Philadelphia early Friday and make stops in Charlotte and Phoenix before landing in San Francisco. At 9:55 p.m., the flight will head back to Philadelphia, with a scheduled touchdown at 6:18 a.m. Saturday.
Special gate and in-flight events, including special meals, cookies and champagne toasts, will take place along the way, but as of Saturday at 12:01 a.m., the 76-year-old airline will officially cease to exist and become part of American Airlines.
As part of that changeover following a two-year merger process, the two airlines' reservations systems also will become one.
