Not sure either..
I had three non-Jetblue guys write letters.. I included them in the attachments section of the application.
Along with a couple nicely written internal recs. that went in through JB's system.. I plan on getting those as hard copies and maybe using 1 from a non-JB employee....
Just need the interview to happen!!
GUY'S AND GAL'S RELAX THEY WILL CALL. If your lucky enough to get called relax the job is your's. Remember all the majors will be hiring in the next year or two. J.B. is a good place to work, but not the only place to work. It will happen for the majority of you, so chill out and wait for your call.
Trust me it will happen over time
