Currently doing this. I was at ACK for 4 years and moderately/aggressively grew my TSP. Cashed out my contributions to pay for flight school. Moved south because it's cheaper and the flying weather is better. Looking at 9 months (accelerated program) to become a CFI, CFI until about 700 hours, then go fly for someone like Planesense. Total time to the major airlines is expected to be 3-4 years. Of course, a lot of making this decision has to do with age, family situation, how settled down you are, etc. I get that not everyone can do this. And if I don't make it, there's always the option for me to get back in. But I have to try. Like it's been stated above, the days off, the benefits (automatic 16% 401k employer contribution), the travel destinations, and the pay is far better than ATC. I have family in the airlines which is what motivated me to make the switch. I also talked to a current airline pilot who started as a pilot, worked ATC for years at a high level tower and a high level TRACON, and resigned to go back to the airlines.
I absolutely LOVED controlling. I am truly passionate about the job. I loved the crew I worked with and the overlying approach guys were absolutely the best to work with. To the guys working 6 days year-round at a level 10+, all my respect to you. However, if you are not happy being forced to live/work at your current facility like myself, I'll be the first to tell you I don't regret my decision to resign thus far. I had to draw the line somewhere as to how long I would stay where I did not want to be. Until NCEPT is fixed, I encourage more people to put their foot down. I spent so many days off looking at NCEPT data which shows how many facilities continue getting AG's and releasing nearly every single NCEPT panel. It is completely broken. ACK released 1 CPC in 3.5 years. Meanwhile, there are level 4-7 facilities releasing 5+ CPC's/year (the revolving door). I spent many days off attending NATCA conferences (CFS, ATX, regional meetings) and weekly Safety Rep meetings. None of it allowed me to transfer where I wanted. And the agency will continue replacing those of us who resign with AG's.
I'm not bashing on anyone in this thread or in the agency. Simply stating that the pay and transfer process needs to be fixed. We all have to agree on that. You all deserve better considering the job you do.
