I understand that AMEX is usually more expensive when it comes to the fees. Still, I just booked tickets with KLM and there it does not make any difference which card I use.
I always weight which card to use in order to get my benefits. And while European cards offer no or nearly any benefits, I do receive good benefits with American-issued cards.
Oh well, one has to be careful... I just thought that Ryanair did not do this before and just wanted to ask if that was true or I was just neglecting to notice. Thanks!
