Still a CFI
Mind you, since coming to my current airline I've used my CFI exactly once. But I still want to keep it current to instruct friends & family in the future, and to leave options open should something happen to my airline career (ie massive furloughs, etc).
Of course, Ameriflight hasn't been using me a lot lately. Maybe I should pick up a student or two as another side gig. Anyone in the PDX area wanna learn how to fly? Leave a comment!
