My ORD-SFO flight tomorrow has shown as 767-300 since I booked it--and is still listed as that. But when I checked seats last night, the seat map showed as a 757-200. Then the map changed to a 767 and now it's a 757 again.

Can't get through on the phone line to check. So do I believe the type of plane or the seat map? With the plane type, my 3F seat is an aisle; but with the current seat map, it's a window. I wish the website would make up its mind!
