I am not sure I understand your method 1 solution. Why does "precisely one person" have to be sitting in those two seats? Two people could end up randomly selecting them just as easy as any other seat on the plane if theirs had been already randomly taken when they get on.

Once either of seats 1A or 1B are occupied, every passenger will have his seat available, so noone will sit in the other seat until the last passenger boards.
