Air Astana will match almost anything starting from library cards to their gold level. I plan to travel that region soon, so I gave it a try using FB. The match cost 46 eur. Let's see how it goes. This should be OT, since AY is not included in their listing.
Library cards are included but not AY? I blame Posti-Turkka. It's a good thing I still have Raisio library vintage card, may get lifetime status with that.*
