Sure, they get a new jet out of it and that leaves a bitter taste in everyone's mouth- and sure, it might not be "right" or "fair" in everyone's minds - but it's simple math.
Buy one jet for 50mil, sell 2 older jets for 27mil - make a small profit of 4 million and only carry the maintenance/fuel/crew costs of one jet instead of two.
Personally, I think they could probably do without ANY corporate jets, or probably COULD just sell one old jet and keep the other...
