Airline card users should check offers listed on an airline's website and use them as a starting bid when calling the airline directly to negotiate a deal or to ask for double points. A notable caveat: Blackout dates and other restrictions can be a common issue with airline cards.
Bank cards are better suited for these types of travelers: those who fly based on price, those who don't want to deal with blackout dates and other restrictions and those who are enrolled in many frequent flyer programs. Users can earn points on purchases and spend them on any airline they choose — points are usually tied to the price of the ticket, so the lower the price, the fewer the points needed.
Bank cards are a better option for those concerned about when they can fly and how much time they have to use their points. Some cards allow users to transfer earned points to a variety of airline programs.
