I had to go through my flight activity to find this info as I was curious about it. Interestingly enough, going through that data it turns out my last flight was on 10/11 ... and it was also my last op-up, sort of. I was "downgraded" from domestic F to int'l C on a 767 new config
Here are my top repeaters

Mind you, these are all domestic flights. There should be a lot more IAD-ROA flights listed on there, but UX always changes the flight numbers. In fact, if there was a constant flight number IAD-ROA, it would top my list with 6 segments.
