More like a shift of equipment/staffing at all domiciles, Eagle likes to do this every few years. One of my class mates has been based in this domicile order in his first 2 years, BOS-ORD-DFW-SJU-MIA-DFW. He also moved to each base besides SJU and MIA. Don't be surprised if you get shifted around the first 2 years if hired..
