Poundage is a problematic topic, and yet, would we really notice much difference if we had to step on a scale (behind a curtain, please)? Think about it: air travel today already feels like a visit to the doctor, what with all that poking and prodding from the TSA. Add a blood pressure cuff and your airport physical is darn near complete.
Might as well bring height into the conversation, too, since that's another issue for a lot of passengers. While Americans were busying gaining those 30 pounds over the past few decades, we added half an inch in height. And tall flyers have troubles, too.
Take the case of Malcolm Johnson, the 6'7" man from Edmonton, Alberta. He launched a campaign against Air Canada for hoarding its bigger seats - the ones with extra legroom - for passengers willing to pay an extra fee for them. Today many airlines charge for these roomier options; it's just another way to make a buck.
Which means, 'too tall' flyers are left jamming their knees against the tray tables and muttering over recent news stories such as Southwest's decision to shrink its seat pitch (well, they mutter when they're not too busy defending their hindquarter space from 'passengers of size').
I'm sure our presidential contenders can feel the height pain since they're a tall group: Mitt Romney stands 6'2" while President Obama is just an inch behind and Newt Gingrich is another six-footer. But again, this only seems to be a burning issue among us non-contenders. I think I know why.
There's plenty of room to spread out on Air Force One. Free food, too. And no TSA.
