If you think you can earn 25K, 50K or 75K MQMs in a year, then it makes sense to shoot for the appropriate Medallion level, if you aren’t going to make it, just spend your money on a decent seat when you do fly.

Figure out what you can sensibly qualify for and stick to that. Airlines stay in business through people chasing status.
