Thanks for that info. The hard part is probably obtaining a balance between studying for the ATPL Ground School and keeping flying skills up to scratch.
It would be great if there was a possibility of working at a company that provides training and air taxi that way I could instruct until I reach 700 hrs then I could split between instructing and air taxi. But in the real world that probably won't happen. I have been an instructor in the Military and a PADI Diving instructor and loved instructing but it is also nice to be able to vary that with other tasks.
Are there FTOs out there that also provide Air Taxi/Charter services?
