And a last, most sneaky one: At checkout if you pay with credit/debit card don't use Ryanair's "guaranteed exhange rate" if the cost of the flight is not in your card's currency (ticket by default, at least two clicks to find and untick it). That's ~6% gap from mid-market exhange rate, the worst cards do better than that.
Yeah but that's general advice, you shouldn't also do that with PayPal, or while paying abroad. ALWAYS pay in the local currency, never in your own.
This is like in stocktrading platforms where "best rate" is offered, and is in fact the worst of several options.

Can we stop with all this Newspeak, already? Words should flow with the conversationalists, not political spindoctor lexicologists.
Even Amazon does this. So scummy. This exchange rate trick should be illegal everywhere.
