I think 2 fares for 2 seats is very reasonable. I can't tell you how many times I've said a silent prayer when I see some one obese coming down the isle. I just keep saying please lord not next to me. I have to relate a funny story. When my parents were living in the south pacific they weighed everyone before they got on the plane then they would walk into the plane and look around and say you and you get off. Those smaller planes had weight restrictions and in a country where you can weigh 300-400 pounds and be considered attractive well it's not a big issue. One time my dad had to help a Samoan lady with the seat belt extension. She sat back and held up her breasts while dad reached across and hooked up the belt. Talk about a fear of getting crushed.
