One thing is for sure - don't expect to touch the controls much for a few years as a new Hire in the WB. Get used to Bunkie life. If you want to fly and have a little fun doing it, go NB FO now and WB later. As enticing WB seems, maybe get your feet wet flying a few months or year in a NB to understand how the United system works and build some flying skills in the 737 or 320 so when you upgrade later you have a clue what's going on. You can always go to WB later in your career. Best of luck and welcome aboard!
