I believe you are referring to the two 737-400s that FireFly bought and was using before TF sunk the jet fleet. MAS is phasing out the -400s so they did not paint them in MAS colors like they did the -800s they brought over. As far as I know FireFly/MAS is still paying the leases on them, so they could gin them back up pretty quickly, I suppose as they are still on the FireFly AOC.
