I recently returned to Salt Lake City from California on a Southwest flight. As we settled into our seats, a jovial, obese young woman eeeeased into the aisle seat, squeezing her corpulence upward and outward to overflow into my companion's middle seat, causing my companion to raise the seat arm between us so she could slide over the very hard metal partition between us and partway into my window seat.
The arm of the "lady of size" (in English that would be fat woman) completely enveloped the arm rest, and as she slipped into a blissful sleep on takeoff, her body seemed to settle more fully our way, like an overstuffed cream puff. Get the picture?
More recently, I read the editorial by the Chicago Tribune that appeared April 9 in The Salt Lake Tribune, which described eloquently how it might be possible to charge passengers for the combined weight of themselves and their luggage, as Samoa Air does now. The author suggested that even major airlines, whose biggest expense is fuel, could save money by doing so.
