I am not so sure about how backed up the 73 is but the scale of that fleet isn't such that I would anticipate absolutely huge back ups in training. It's really jacked up on the 74 and 76 though. Last I heard the 76 class that is starting now will do a week of indoc and then be sent home until April. I hope that is just a stupid schoolhouse rumor. In any case the 73 isn't going to be a time builder regardless. So if Atlas is where you want to be welcome! But if this is looking like a stepping stone to you I would looking elsewhere to build time faster because it will probably take you over two years to get 1000 hours from date of hire.
