Most of Wheels Up's planes are junk. Worn out King Air 350's and Beechjet 400A's

The reason they are not profitable is because their planes go down for maintenance every other leg.

If you enjoy sitting around at airports for days, waiting on your plane to be fixed than it is a great place to work.

If you like racking up hours in your logbook, than work for a company that doesn't have to contract out every single maintenance job.
