"It's in our policy". Which of course is very true - however seeing as I only looked at the policy when I went to check in online (which was a couple of weeks after I had sent in my passport with the application form for the passport for my baby) I was hoping to appeal to some good nature on their part, that a copy of my passport, stamped in a Garda office, with a comment from said Garda stating that he certifies that this copy is a true identical of the original, would be acceptable once accompanied with a drivers license. I should of course have known that Ryanair staff are robots who don't stray from "the policy".
I'm now hoping that the passport office will accommodate my request that I give them my wifes passport with the application form in place of my own, they're to get back to me later.
