No. I'm sure there are many who agree with you. And many others who would disagree. You've picked a route where AA & partners have a ton of capacity. There are plenty of other routes where AA & partners will fall short on what UA & partners have available.

That's why it is important to make decisions based on how YOU earn and what YOU want to redeem for. Anyone who says there is only one "best" program out there is either lying or trying to sell you something. And probably both.
