ATL is dying. Denver is shrinking. This is a snapshot in time. When I got hired DAL and MCO were both 5 years to hold as a FO. There have been multiple times since that new hires and new upgrades have gone to both bases. At one point, MCO had 7 year captains awarded.

ATL is being kept around because of nostalgia. I suspect it will be the first SWA base to close. DEN is going to shrink and grow as the company sees fit. This is a fickle business. There will be a time again when things flip on their heads. We have 2
years of stagnation and are getting ready to get an injection of new hires and upgrades.
