Standard CFI-Regional situation. I'm an FO for Horizon now and applied a while back using the internal job posting rather than the external gateway for other pilots. Someone told me the other day that they're working through the backlog of Horizon applications from 2015 that never received an interview but i don't know yet if that's true.

Also, thanks for the link for Rainier, I sent them a message last night. They were recommended to me last week too, so I'd guess they're a pretty sound way to go. I appreciate it.
