Incredibly.
Key Lime has a horrible record in the freight world, they've required PFT in the past and their MX and safety records aren't much to speak of. I flew with a captain here that flew a Navajo around for them for about 2 weeks, and he talked about things like being told to fly with one de-icing boot inop, bad alternators, etc. etc.
I'd stay far, far away from Key Lime unless you've got a lunch date with Jesus you really want to make.
