As of May 15th, JetBlue has 6 candidates who are fully vetted (background checks, PRIA, and drug test done). My understanding is that those candidates will be offered slots in the class that starts on June 8th. The classes are now running at about 12 pilots per class and they have announced that classes will be starting every two weeks through the summer.

What that means is that the pilots who interviewed in the beginning of April will most likely see classes starting on that day for a half dozen lucky few and continuing.

JetBlue also doesn't necessarily place a pilot into class in the order in which they completed the vetting process. They like to have a mix of pilots from different backgrounds, a la, a few with Military, a few Regional, part 135 or charter guys.
