RT award travel on this route will require at least 60k miles. Information on credit card bonuses is available elsewhere in this forum. Your best bets for obtaining award travel are on AA and UA, both of which also offer OW travel for 1/2 mileage. AA does not fly to Europe from the Washington area, but you could make use of IB for flights to Madrid from other US cities. I suggest that you choose either AA or UA, and that both you and your wife then pursue the most appropriate credit-card bonus applicable to that program. That in itself could give each of you enough miles for a OW ticket.
