Common Aircraft Tail Letters


#1

What is last 2 letters on the aircraft registeration such as ExpressJet Airlines Inc. dba United Express and Skywest Airlines and Mesa Airlines dba United Express?


#2

It is usually indicative of who owns the AC.


#3

Most expressjet ERJ’s do not have letters in their registrations and instead use 5 numbers, like Continental Airlines aircraft (who was their parent company at one time). The Expressjet CRJ’s letters often indicate their original owner or operator, with AS common for former ASA-operated aircraft and CA common for former Comair operated aircraft.

Most Mesa CRJ-700’s flying for UAX have “MJ” suffixes. I do not know the importance of the initials MJ, but these aircraft are owned by and were initially delivered to Mesa.
