ExpressJet recently merged with Atlantic Southeast Airlines. They still use the ExpressJet name however they also now use the “Acey” callsign and ASQ code (rather than BTA).
On FlightAware all ExpressJet flights now show up as ASA flights. For example flight ASQ5714 shows up as an ASA flight even though it is an ExpressJet flight. Not much of an issue if you know this stuff but say someone is on ExpressJet 5714, and when they look it up on FA they see a flight which landed over a year ago rather than the correct one, and things can get confusing.
Just a heads up, someone must have missed a memo or something because FA was right on the ball about switching from UA-CO. Of course, in that case they all started using the UA callsign/code while ExpressJet retains its name but now uses the ASA code.
Just something that has been bugging me for a while and I was hoping you guys could fix it.
