2-seats fatty sues airline

December 21, 2006

A 26-STONE man is suing Air France for £5,000 after being “humiliated” by staff who weighed him, measured his waist and charged him for two seats.

French writer Jean-Jacques Jauffret, 41, paid an extra £400 to fly home from New Delhi, India.

He told a court in Bobigny, near Paris: “I felt ashamed and belittled when check-in workers asked me to step out of the queue to be weighed.”

But Air France lawyer Fernand Garnault said: “This man can barely balance on his chair in this courtroom, so how is he expected to squash into a small single seat on a plane?

“The plane was full and it would not have been fair on other passengers to allow him to take a second seat for free.” The case continues.
