“I was asked what size clothes, and how much I weigh. I gave answers in front of a gate full of people, some of whom were snickering,” Tiggeman said.

Tiggeman, who once weighed 393 pounds, is down to 268 pounds.

A spokeswoman for Southwest said: “If a passenger cannot fit in a seat with the armrests down, a second seat must be purchased. If the flight is not full, that added charge will be refunded.”

But Tiggeman said she does fit in a seat.
