I flew there 6 or 7 years ago. Training at Frontier (at that time the 1900 operation) was great, better instructors than I had experienced in the L48 and generally more interested in helping you make the best of it rather than running you through a washing machine.
I ended up not liking the operation itself and moved on to Yute Air (which was fantastic in comparison as far as QOL was concerned), then ended up where I am now.
