As a frequent international flyer, I was bemused by today's article on the theory that the combination of what you and your luggage weigh could determine the cost of your plane ticket: http://www.nbcnews.com/travel/u-s-f...ld-buy-second-seat-1C9511172?ocid=msnhp&pos=1. I'm a medium-sized person with a bad habit of overpacking, especially shoes. If I lose weight do I get another pair of shoes in there? Seriously, this looks like a discrimination case waiting to happen, but the weight restrictions on luggage do seem to set a precedent that heavier can cost more. I really am not sure how I feel about this.
