@adam.smith neither have I, but I have had plenty of flight's where the map was only half full, only to board the plane and find the thing nearly maxed out. I think it happens often in YMM, there's lots of guys here who travel a lot but still don't know how to do it, so they never select seats or anything. So picking a solo seat, or picking 2 seats and leaving the other open there's no guarantee that even hours before the flight that someone won't be stuck there.

Point being, I never 100% trust the seat map
