My daughter will be attending the University of Barcelona in the spring and my wife and I are going to visit her during holy week. We are trying to decide what arrangements to make to fly there and get around in Spain, too. We will visit Barcelona, Granada, Santander, Bilboa, and Madrid. Iberia's SpainPass appears to be a good deal for flying in Spain domestically, but you must fly to Spain on Iberia to get that deal. We could fly on other airlines and upgrade to business class with points to get to Madrid or Barcelona, but we can't upgrade on Iberia. Does anyone have any experience with the SpainPass or flying from the US to Spain in economy?
