Every time you blink, it seems like airlines are trying to find new ways to charge us more for a flight.
But a new study is doing their work for them, suggesting airlines price seats based on a passengers weight.
Professor Bharat Bhatta, the man behind the study published in the Journal of Revenue and Pricing Management says passengers should self-declare their weight when they book a ticket.
One airline called Samoa Air has already adopted a similar policy, and Southwest Airlines requires very overweight passengers to book two seats.
Do you think the policy seems fair?
