Upgrades will be less than 2 years for many years to come. You are in a good position, much better than at XJT. You will have guaranteed attrition ahead of you to AA and there are still 40 options on new airplanes. Get your 1,000 SIC time as fast as you can and you will leapfrog people senior to you. Those that are saying the quick upgrades are over do not know what they are talking about. With the exception of a few places, short upgrades will be the norm at most regionals without a bunch of lifers and no flow/pref hiring agreements. Just concentrate your energy on training and don't worry about the upgrade.
