I've flown this flight SFO-IAD 5 times in the last 2 months and 3/5 of them we've had an equipment swap. It's supposed to be a 3-class 763. Here's the last few days of history:

27-Aug: B772
03-Sep: B772
05-Sep: A320
06-Sep: A320
07-Sep: A320
08-Sep: B752

I'm looking at Flightaware, so it doesn't show when they've swapped a 2-class 763 (happened to me once) . . .

Is there a record for flight-most-type-swapped? The one time we swapped to a 752, there were a LOT of angry elites who sat in back (not to mention the ~50 or so people who got bumped outright).
