usually enough times to keep an eye on what is going on at my airport, unless I am at work, and then even more, since it is AT the airport. I would say I average going on FA around 10-15 times a day.
I visit whenever N28FD is flying, or a friend is on a commerical flight. I’m addicted. I have two flat panel displays at work, one always has FlightAware going while I work on the other!!
and I like to read the Forums at lunch from my iPhone.
I check several times a day, though I don’t visit the forums each time. I check airports throughout the southeast, esp. Georgia, North Carolina, and Tennessee. Plus, I sometimes am watching MCO while listening to their ATC on LiveATC. As for individual aircraft, I check some local planes, plus Harrison Ford, John Travolta, Donald Trump, etc. I also watch KVPC a lot, for some of those Phoenix Air jets going off to all corners of the earth.
