One thing to consider is that ALL the major airlines now have contracts in place which allow them to use 76 seat regional aircraft. Almost all of ASA/XJT, Eagle are 50 seats or fewer. This applies to many of the other carriers too.
There is going to be a big shake-up coming as the transition to 76 seat aircraft occurs and as some of these regionals go out of business. XJT is losing about 50 aircraft by year's end. You are getting in during a time of much needed optimism in this industry, but also great upheaval. UAL lost 200 + million last Q while Delta made 200 million. There could be a substantial shrinkage in the regional airlines as the 50 seaters are retired. I think this summer is going to be chaos even more than usual.
Just some things to consider before jumping in right now.
