Well, my personal September results are in and the results remain dismal. I flew 6 CPU-able flights in September, and was upgraded on a whopping two of them, for a 33% success rate (based on flights; based on upgraded miles flown over all miles flown, the rate drops to something like 11%)

The two successes were on an RJ for 300 mile flights. The four failures included an A319, A320, and 2 PMUA 757s. Only one of the failed flights was hub-to-hub. One was a flight I've taken many times and was consistently upgraded as a 1P since the dawn of UDU.

On the last flight, yesterday, it was clear that UA held back significant inventory to sell, and was reasonable successful at it. I began at just before T-24 as #1 on the list but gradually fell to #4. I was thinking things looked pretty good with 6 open seats in F. But overnight and throughout the day approaching departure, the number of F seats dwindled and nobody else cleared.

I'm definitely seeing more and more 1Ks joining me in the exit rows lately, and I'm definitely not feeling the love from United. Personally, I feel compelled to stay to reach 1MM but I will likely be gone after that (at 0.9XX MM now).
