I'd go for LGB and fly jetBlue for many reasons, snacks are great onboard, nice airport, cheap parking, and on sundays, they have a brunch buffet upstairs in the cafe thingie that overlooks the airport. On top of that, you get 1 inch more leg room, wider seats, comfortable leather seats, 24 channels of live DirecTV, and cool in flight crew... need I say more? Never experienced traffic going to LGB, however, if you fly out of LGB, check in 2hrs before your flight, the line tend to get longer about 90 minutes before departure. If you dont have check luggage, use the self check in, almost no one uses it and saves alot of time.
