On the plane over, I was sitting next to a kindly anesthesiologist from Dallas who promised me that he'd be more than glad to let me out at any time because he knew how bad it was to have the window seat. Then I had to confess that I preferred window seats - that's all I booked. I want to see out.
At one time, I booked the aisle seat because everyone told me they were "better." But after a few times of staring out the window over someone's shoulder, longing for the seat with a view, I have gone back to booking my window seats.
And, yes, I'd even pay $15 more for a window seat! ;)
