I was an instructor for Lufthansa Air Training in Florida however they had shut down their doors and told their students to look for other work amid the pandemic which is understandable. I believe they still operate a school in Goodyear, Phoenix Arizona. ATP will do what they say, a bit higher priced but once the industry comes back, I am sure they will be flooded with students. I had a couple friends who instructed for ATP, but once they hit their 1500 hours, they lost their jobs to make way for new CFI's as ATP guarantees a CFI position to students who meet eligibility requirements.
