Questions on Flight Monitoring

A couple of questions.

What is the difference between a EJM (Executive Jet Management) Flight and a EJA (Netjets Aviation “Exec Jet”) Designated Flight?

and

Are BBJ’s listed in flight following as BBJ’s or are they listed as Boeing 737’s ?

Thanks in advance.

EJM and EJA are two different companies with similar codes.

The BBJ’s are, as far as I know, listed as 737’s. Here’s an example: flightaware.com/live/flight/KAI99

Thank you. Much appreciated.

EJM and EJA are both Netjets. EJM is the on-demand charter portion of Netjets while EJA is the fractional ownership side of Netjets.
