Samoa Air announced this week that it will begin charging airfares based on the passengers' weight.
The island hopping carrier is the first airline to charge fares based on weight, saying that it will ask customers on its website when they book tickets how much they weigh and then double check the weight at the airport on its scales.
"We at Samoa Air are keeping airfares fair, by charging our passengers only for what they weigh. You are the master of your Air'fair', you decide how much (or little) your ticket will cost. No more exorbitant excess baggage fees, or being charged for baggage you may not carry. Your weight plus your baggage items, is what you pay for. Simple," the carrier says on its website.
Dallas-based Southwest Airlines often asks passengers of a certain size to purchase a second seat but does not weigh the passengers.
Samoa Air is a small airline, with three aircraft - two 10-seaters and one four-seater.
"We have to take care of every passenger. We have to take into account that not all people are the same shape and size. The bottom line is that airplanes run by weight; they don't run by seats," said Chris Langton, Samoa Air's chief executive told CNN International.
