My friend is getting old for economy (understandable in this day and age of flying), but he'd still like to take a few extended vacations per year. He is not really a wizard of credit cards. Can an old dog learn new tricks, and does it worth it, for his use case? At worst, there is always an 80/20 solution for everything, I thought. (What's the 20% of work you can do which yields in 80% of the results?) I learned about this (now it seems to be discontinued, and anyways unsustainable) trick on how to score nearly unlimited business class tickets for $500 a piece. My friend doesn't even need unlimited of them, and the $500 a piece price may be just too good to be true, anyways. What best practice actions could you best recommend to my friend? I thought this was an OK way to break my silence, 6 months after my registration.
