Same case here.
I was flying from Madrid to Porto and lost my ticket paper. These Ryanair ###s charged me 40 Euro for printing a new ticket. Considering that I flew with them 2 days before (going from Porto to Madrid) and having in mind they had all the info needed on their PC sreen (I gave them my flight reservation code and ID card, what else do they need? A DNA sample, perhaps?) I think its just plain stupid to surcharge passengers for something that can happen to anyone and having such an easy solution, i.e., printing a new piece of paper and maybe charging a simbolic value like 1 euro (more than enough to pay for that cost).
I'm sure all Irish feel embarassed for having such a piece of crap company representing their country. Rayair doesn't seem to understand that "low cost" doesn't mean "low ethics".
But hei, no problem, Ryanair! Since I feel robbed and you insist in not having an online form for complaints, I can always promise you that I will never fly nor reccomend your company to anyone I know.
