If you click on the earlier story at the bottom there's this:

A spokesperson for Ryanair told the BBC: "[The family] unchecked themselves on the website on 22 July and ignored the pop-up that warned them they would have to check in again and generate new boarding passes.

"As they didn't have valid boarding passes, they were correctly charged the airport check-in fee."

Mr Lloyd denies this, saying: "I can't remember going on the website after I checked in.

So he sort of denies/doesn't remember. Maybe he had a pop-up blocker? But even so, someone must have physically checked out with or without the warning.

But yes, as you say, strange story.
