GAJ call sign

I have been seeing a lot of GAJ call signs. Who owns these planes? ex: GAJ17

Could you post a link?

There is no ICAO airline designation “GAJ”. Probably a mistake with the code. It’s not uncommon to see planes flying around under the wrong code.

GAJ is the three letter civil aircraft company code for Gamma Charters, Inc., of Stamford, CT. FlightAware hasn’t updated their database. GAJ is Gamma Charters, Inc. of Stamford, CT. Source: Changes to Order 7340.2B, Contractions, Chapter 3, Sections 1, 2, and 3
