It's probably far more worth it to just buy whatever is cheapest, yet most comfortable. If you see an AA MCE seat for the same price as a Delta C+ seat but the Delta flight is nonstop, take the Delta flight. If you see an AA biz fare to europe for $3k but the same on Turkish for $2k, take the Turkish. There's no level of status that makes it worth it going out of your way or sacrificing comfort if you're only flying that much.
