Until *A carriers implement Alliance upgrades, it is essentially worthless. I usually *avoid* flights on other *A carriers since the only perk is lounge access and status miles. I don't even get my 1K bonus....

My thoughts exactly. Maybe it's something in the SF drinking water

For revenue flights, I use *A carriers only for short flights which UA does not serve. It is painful to not get the 100% bonus miles on long-haul flights. If I were a no-status member of MP

I might be indifferent to which *A carrier I selected.
For award travel, UA often has the "cheapest" awards, and the C or F class starts at your point of origin. I simply don't see much point in using other *A carriers for either earning or redeeming miles.
