I'm looking to minimize the cost of the companion. As there will be more freedom to travel together this year, minimizing companion cost would be great. Going for full priced award tickets would drain my M&M account pretty quickly, so looking at other options.
I knew about AMEX and will probably go for it, as it would pay off in 2-3 trips compared to other mechanisms.
