I spent a lot of time on planes during my almost twenty years at IBM.
This map is based on all my TripIt entries, and they only go back to 2009. I would base it on memory, but I'm managed to suppress a lot of them.
This is only the business trips, since we had vacation travel during that time, as well. 2009 was about when I moved to Lotus, because the years before that, I was spending one to two weeks a quarter in Europe, but I was going to Stuttgart and Paris all the time. (The only business trip seared in my brain, although I don't remember the year, is documented here.)
I know I went to Australia at least twice (including once for two days) but that was pre-TripIt. (One of the trips was pretty much pre-Internet.) Still, this is a lot of mileage.
