Bravo to a brave male passenger who confronted the American Airlines bully (aka flight attendant) who hassled a woman with a baby on Flight 591, from San Francisco to Dallas-Fort Worth on April 21. Just when I was beginning to be worried about the notable absence of passenger solidarity in support of David Dao on that United Airlines flight, along comes Sir Galahad to renew my faith that chivalry is not dead.

Unfortunately, that courageous traveler seems to be the exception. Witness the latest episode of passenger abuse aboard a Delta flight from Hawaii last month. The viral video shows the poor husband/father being hassled by both cabin crew and security officers. He has to deal with these authorities on his own, with no other passengers coming to his aid.
