This seems like a reasonable policy.
Air France is to offer a free second seat to obese passengers “for their own comfort”, the airline has said.
Overweight passengers can already buy an extra one with a 25% discount, but from 1 February, this will be refunded if their flight is not full.
It also confirmed that, in common with other airlines, an obese traveller could be prevented from flying.
This was to ensure a flight can be evacuated within 90 seconds, the BBC’s transport correspondent said.
It came down to the discretion of the captain whether to let them fly or tell them to disembark for safety reasons, Richard Scott said.
