JAA License in the US
Getting a US certificate is not that big an issue, just a written and a flight check. Hell they give you a Private Pilot Certificate just for the asking. Of course its only good as long as your License that it was issued on the basis off is valid.
Now for the guy who dose not think he is qualified to apply to jet blue, since you have time in the kind of airplanes Jet Blue flies, send a resume, you are only talking about some postage or a fax for godsakes. Never shoot yourselve down on applying for a job. If they don't offer you an interview, what have you lost? Nothing! Let them say no, you just go and apply. You know if they really need guys with time in type and if there is a short fall of guys, you may end up with a job. Give yourselve a shot. Send them a resume, you may be surprised.
I never understood that you can have a Frozen ATPL, here in the States, you have to have the flight time in the logbook before you can take the Checkride. Its just a funny way of doing things, maybe its just a europe thing.
