Just remember, you are getting a regional job. No better. JetBlue is an alright place to hang around at for a few years while building time for Fedex, U.P.S, any of the network carriers, Southwest, or any of the good jobs in aviation.

EMB-190 first year FO pay $47
EMB-190 max captain pay $94 (less than Mesa for an even larger plane!

A320 pays reasonable. Some people will point out it is in line with United, US Air, and Northwest, but remember the A320 is either the smallest (or second smallest) aircraft for each of these companies. And that is after they have taken something like 40-50% pay cuts. I'd assume those rates will be coming up in the near future. Regardless, even at today's rate, you can max out over $50,000 a year higher at any of those companies. That adds up over 20 years (about a million dollars)
