I'd add, by the way, that if you go the business class route, you might be able to put together a similar strategy with other airlines as some of their business class awards during the offseason might be comparable, and all of these airline programs have similar shopping malls and dining programs. None of the other programs, however, has a similar avenue to massive miles through credit card apps such as the Citi/AA route. If your GF participates, however, you should be able to put together something with Chase's Sapphire Preferred and United cards.
