How much did all those MRs cost you and how many upgrades could you have purchased with that money?
For the record, I reached 1MM on UA about the same time they introduced the PQD program; I was multi year 1K with very limited MR travel. Everything self-funded. I chose a mix of options 1 and 3 - some allegiance to AS but willing to buy elsewhere if beneficial to me (also needed given AS route network). Fairly satisfied with my choice.
