Never taken JetBlue, but a payraise is on the way, and yes I have considered it before, especially going from OC to Vegas. However like others mentioned, it always seems at least double or more expensive for the ticket and, well, I'm not a 6 foot tall guy so I'm not exactly completely miserable saving some alcohol money to sit in with the general public for a couple hours.
Long Beach Airport is the shit and one of those last few gems in the local area that hasn't been destroyed by overpopulation or mexicans (that's for Cal).
Basically, it takes you 5 minutes to drop or pick someone up because there's no traffic, and then getting on the plane is super laid back, and you literally walk on the tarmac to get on or off the plane like the President does. Super basic, simple, and the place hasn't really changed in decades.
Once dealing with Long Beach, LAX is like a huge razored dildo up the wazoo.
