I'd be way under the MQS pace, but my Butt would most definitely spend a lot of time and miles In Seat.

A bicoastal consulting job could easily generate that sort of travel pattern; it's not like cheap mileage runs to SIN or HKG or wherever. That's all nonstops, so no minimum segment mileage for bogus connections. Perfectly legitimate and very frequent flying, but in a competitive enough market that the MQDs aren't there unless you're buying F/P/A/G all the time.
