Yes, it was on the show, though I don't remember which episode. (I don't fly WN, didn't know about the refund policy, but remember that it was explained to one passenger on the show.)

I think the funny/sad part of their policy is that it isn't uniform. On one of the shows, they showed two passengers of size being checked out on the plane. The larger of the two was able to fit, the smaller of the two had to pay for an extra seat. (It looked like the fact that he needed an extender was what made him have to pay up, which doesn't seem like part of the policy. The other guy would have needed an extender also, but they didn't make him buckle up .. all he had to do was to show that he could lower the armrest without infringing too badly on the seat next to him.)
