Excess baggage might not be the only additional charge at the check-in counter.
People weighing more than average should pay more for their airfares than slimmer passengers, according to a former Qantas executive, the Daily Mail reported.
Tony Webber's "fat tax" idea, he said, was because airlines were paying more for fuel because the average weight of the population had increased.
The extra fuel needed cost about 315 pounds a plane, he said, and additional weight of passengers affected airlines' profits.
Webber, who has a PhD in economics, claimed low-cost budget airlines were already considering the idea.
