Have been a 1K since 2011. Had 150K miles last year on 13k spend.
I know I am going against the flow here. But My GPUs always clear and never go to waste. I am very happy about that! CPUs not so much but it is a business and I understand.
Few things get on my nerves from time to time but overall very happy with United but I am not at all happy about the new mileage rules starting March 1st

Will be staying with United as I am pursuing the 1 MM mark mostly because partners such as Lufthansa, Air China and Turkish go to places I wanna go to.
