Fortunately, this airlines is small, but it's radical idea just might be something that other airlines follow. The airlines is Samoa Air, and even though they only have two planes, they might just start another trend in airline fees.

Under this new policy, passengers are charged based on their weight. Rates range from $1 a kilogram to more than $4 a kilogram, depending on the distance of the scheduled flight. Don't plan on saving money on baggage fees either because baggage is charged at the same rate. A kilogram is the equivalent of 2.2 pounds, so a full 80 pound suitcase could cost you as much as $145 on a lengthy flight.

With the average weight of fliers getting heavier every year, this just might catch on. What the heck, what's one more fee?
