If Miami Air went under, I am sure Swift Air and World Atlantic are probably next on the chopping block unfortunately. I would of guessed Miami Air would've been the last to go considering they are larger than both SWQ and WAL. Atlas Air is large and has their cargo business so I am sure they are doing okay.
Somehow, I think SWQ has a better chance to come out of this pandemic than WAL. Swift has enough charter contracts, particularly with pro and college sports teams, that once those sports resume, SWQ will overcome the pandemic. I don't know enough about WAL to comment about their situation.
