Hard to say...flightaware shows each of the three registrations are operating return from one destination per day (two flights - there and back. PER, BNE, and CNS all feature).
There's meant to be a fourth being added to the fleet...not too sure what timing or tail number that'll be. Possibly VOM
The 737 HOTC has given notice that he is stepping down and leaving the company; whilst the HOTC for the company is stepping down to become a line captain. Hardly stuff that gives you confidence for what's going on inside HQ
