1. Prior Aviation at the Buffalo airport has been around forever, I have not used them so I won't recommend, or not recommend them.
2. If you are flying more than about 300 hours a year buy an airplane and hire me. I will be available in a bit over a month.!!
Depending on your flying, the type of airplane etc. the rough rule of thumb for breaking even on costs is: less than 200 hrs per year charter, 200-300 fractional and more than 300 buy your own. Fractional use means an ongoing commitment and if you add up the costs is pretty expensive if you calculate the per hour costs compared to owning your own but makes sense for consistent light to moderate needs.
