The L.A. Clippers just got another first class ticket to Dumpsville -- a rep for Virgin America tells TMZ Sports, the airline has officially decided to discontinue its sponsorship of the team.

The rep tells us, "While we continue to support the fans and the players, Virgin America has made the decision to end its sponsorship of the L.A. Clippers."

Virgin America is just the latest sponsor to bail on the Clip Show in the wake of the Donald Sterling audio -- as we reported, CarMax has already severed ties with the team. State Farm has ended things too, at least for now.
