Great topic, Rusty
I am a 1K on United, and fly exclusively the cheap fares. I am at 110,000 miles this year already.
My last flight was from SMF - PVD for $220 RT, where UA matched WN's $99 fares...then used my confirmed upgrades to FC.
I get wonderful customer service from just about everyone at UA. And when I mention that I am flying on really cheap fares, the reaction is "we're glad to have you aboard on any fare."
Of course, that's from the troops in the field, and not from the MBAs in the corporate office.
I plan my own travel and take advantage of all of the fare sales there are...thats how I have gotten to close to 1 MM miles.
I will never make UGS...thats ok. I still give United $30,000 a year. I just get a whole lot of flights for that $30G
