I was wondering what, if any, service you use to keep a log of all your flights you've taken. Personally I use FlightDiary.net and I feel it gets the job done quite well. However, if you have any different service you use I'd love to hear about it.
I use Flightdiary for the most part these days. I started with flugstatistik and still use it occasionally because I have found FD's database is somewhat limited and they aren't all that great about updating it pursuant to requests (I've had issues with the FD database not having smaller regional airports in the USA and smaller defunct airlines).
Each have their pluses and minuses. FD can get unwieldy once you get a bunch of flights logged.
