What's really interesting is that this low-cost airline might still SELL you tickets to row 13.

A few days ago a couple of travelers boarded the plane and couldn't find their seat. The stewardesses were baffled as well.

EDIT: Apparently there was a last-minute switch of planes and some of them do have this number, while other don't.
