Amount in Polish zloty? Question about booking flight from Poland to UK.

I am trying to book somebody a flight from Poland to the UK, but the amount is in Polish złoty. I am paying with a card from the UK, with GB pounds. Will it take the right amount from my card? Will it even take anything from an account in this country? How does it work?

They'll take the GBP equivalent at the bank or airlines exchange rate, if you get an option to choose which you should and definitely will with Ryan Air choose the banks exchange rate, it will save you about 6%.

It's okay I found a way to bypass it. You open another tab, book a flight on it from the UK to wherever [if you want GBP] and then click on continue. When you go back to your original booking and click continue, it changes to £ as well. It's weird but it works.
