I requalified for 1P Premier Exec on 11/19 with 50,099 miles - 50 segments.
That's it for me this year on UA unless there's a fare I cannot pass up before year's end...
Most I've flown on UA the last 4-5 years was 60,000 miles; that was because I was at about 56,000 and only needed one more cheap roundtrip to grab another 4 e-upgrades.
