What struck me as amazing was the pilot's decision to keep the plane's DirecTV Inflight Entertainment on for most of the ordeal. What an excellent decision. I know if I was in the same situation, I would want to have as much information as possible. At least I wouldn't be distracting the important work of the flight attendants asking for information. For those who didn't want to know what's going on, they could always switch off the TV or change the channel.
I've heard good things about JetBlue before this incident, but have never flown on it because they don't have flights to Columbus, Ohio. I would still fly JetBlue if I could. It would be my airline of choice.
