The only other way I can see to do it requires weighing passengers. To do this is have a seat fee and a weight fee. Seat = $100 + $1/lb for example. You take one seat and weigh 50lbs, you pay $150. Two seats and 400lbs... you pay $600.
At 6'5" and 210 pounds, I exceed you arbitrary weight. However, my ht/wt is proportionate and I do not get close to encroaching on the seats next to me. I'm just wondering how you arrived @ 190 lbs as the threshold for paying for an additional seat.
