LAX: Man attempts to self upgrade, as the police are called.

Police and TSA officials meet a Delta Air Lines flight on Nov. 1 at Los Angeles International Airport after a passenger, upset about the customer service he received on a flight, attempted to "self upgrade" on board, a law enforcement source told me this week. 

I'm pleased to report, however, that there was no overreaction here. The man went back to his seat, the source said, and the TSA and police let him  go, saying it was a customer service issue. 

Have you ever been tempted to self upgrade?
