The problem is that even KVS shows availability and maybe Iberia internal system, when you want to redeem with some non-OW airlines (Ex Avianca) they take the information from Amadeus regular reservations. Iberia used to keep their U (business) and X (Economy) on the reservations systems until July 31st, somebody knows if it will upload again X and U classes. The flight I want to make it's MAD-MIA Dec 22nd 2 seats on Businnes. I checked it out on Expert flyer and it's not available.
