A little bit of good news...
They moved up the April upgrade class to March 24th and they made 2 upgrade classes in April instead of 1 for a total of 6 upgrades in march and 24 in April. Better than the original 12 only planned for April.
However after the 12 more upgrades planned in May there is not another one scheduled until September. Hopefully those get moved up as well.
I heard that Mesa refused alot of flying over the summer do to their poor staffing and that is the reason for moving the upgrades up a few weeks.
