I flew 91/135 for about 9 years. I enjoyed every minute of it at the time. I do have previous 121 time with a regional before that. I am currently flying 121 cargo stuff and not too happy right now. I have my app in with F9 as well and hoping to get an interview soon. I’m looking forward to get back to the 121 pax side for multiple reasons. Yes, the ULCC model seems to be going very well right now and hopefully will continue to go well into the future.
