I took JetBlue too and from Long Beach to Las Vegas. There's nothing to complain about. Total flight time was less than an hour. They quickly passed out soda or water. Then quickly passed out the cookies or chips. Definitely go for the Terra Blue Potato Chips. Delicious.
The screen on the back isn't as good as the Virgin airlines ones. My tray was broken on the way to Vegas, so -1 there.
