How about those of us that fly both?
I have 97,357 miles flown on HP this year and 27,109 on US this year so I spend a lot of time on both. Honestly I hope it becomes less like US and more like HP but I've only been Gold on US so that may be why. HP just feels like a nicer operation overall to me but I've flown maybe 10 to 1 lifetime HP vs US so maybe that is just what I'm used to. However I've flown more on DL than all other carriers combined and I sure hope that the program becomes nothing like it is today on DL.
