Hey bud -- if you're talking about the 737s, you're likely looking for Sun Country Airlines. They operate the Amazon Air fleet as a partnership. Airline Transport Services Group (ATSG) does most of the 767s, through Atlas Air, or Air Transport International, orrrrrrr ... There's another in there. Some shop in Miami I can't recall. It ain't Cargojet.
Any other info, I'll try to fill in the blanks. The title caught my eye because I somehow thought this was an ask for Primera...
