All speculation of course, but still a question that crossed my mind..

Let's say Delta bought Jetblue and they merged. Do all the pilots morph into Delta pilots or do B6 pilots have to interview with Delta and meet their standards? For example: The 4 year degree requirement delta has in place. I know most B6 have one also, but not all of them. Do those without the 4 year suddenly find themselves in the unemployment line?
