Have had this happen twice in the past 2 days. Booked several a flights months ago in BC, selected my seat, looked at the PNR yesterday and I had been moved, many seats left in BC but was moved to the seat adjacent to the washroom. Have a flight next Jan 2013, same thing, selected my seat BC and when I looked yesterday, moved to the exact same seat in BC adjacent to the washroom, and according to the seat map, I am the only one in BC at this time. Is this done manually by a Res agent or is this done automatically by a computer.
