Buying a ticket now is the equivalent of a down payment, Boyd says, as airlines look for ways to charge passengers for everything from water to luggage.
Still, there's something sad about showing up at the airport knowing I won't have to pay an overage charge due to the heavy stacks of black plastic swelling my luggage.
Some fuel cells can charge a device roughly 12 times before needing a replacement cartridge of butane (which the US government permits in checked luggage on airplanes).
