An entire cottage industry has emerged for products that help people evade the baggage-check fees, according to Kate Hanni, director of FlyersRights.org, a consumer group that represents airline passengers. Ms. Hanni uses vacuum-seal bags inside her carry-on bags, she said; the bags, which shrink down to a compact package when air is pulled out by a vacuum cleaner, allow her to fit considerably more items in a carry-on than would normally be possible.
"I can fit three times the amount of clothes in a carry-on than I used to be able to," she said.
There is also the Scottevest line of travel clothing in which trench coats, vests and other garments are made with large built-in pockets that allow people to carry everything from folded shirts to an iPad.
"You can fit all of your folded shirts, iPad, cellphone, iPod, sunglasses, camera, passport, keys - you can put everything in the jacket that you would put in a carry-on," Ms. Hanni said. "It's sort of sweet justice."
Vacuum-sealing all of your clothes into little plastic bags for the flight out seems like a reasonable idea, but how do you get your clothes back in the bag so you can come home? Whoever solves this problem will make a million!
