Change of passport number

[Hammers1]

Going on a Ryanair flight tomorrow with my wife. For some reason we managed to put in the same passport number for both of us when checking in online. As far as I can see I can't change the passport number online.

Can I just call them on 00353 1 2480856 and ask them to change it? And is it free?

Any help would be appreciated.

If the incorrect and correct passport numbers are similar, there won't be a charge. They allow for small errors like that. But if not, you'll have to pay.

Cheers, much appreciated.

The numbers are the same, my wife's. Sigh.
