An American airline won the right to have weighed its passengers over a six-month period earlier this year to learn how it can save fuel, after discovering the average passenger and carry-on luggage was heavier than expected.
Hawaiian Airlines has now scrapped pre-booked seating for people flying the 2,600-mile route between Honolulu and the American Samoa.
Instead, they will be assigned seats when they check in to make sure weight is evenly distributed around the main cabin of the plane. The airline will keep at least one seat open per row or place children under the age of 13 in those seats.
Some passengers said the policy was discriminatory as it only affects people flying on one route, from Honolulu to Pago Pago, with most passengers being of Samoan descent. Samoans have among the highest rates of obesity in the world.
