They finally replied to me. I think only 1 guy checks the email and he must be out the previous week. He replied to all my inquries from 2-3 weeks ago altogether.

Facts: you can book book UA and US mainline. No United Express, etc.

-Go to united.com or usair.com to find the saver award seats.
-Call Qatar Privilege Club (expensive long distance) and have them set up a PNR with your desired flights. They'll confirm whether flights are available.
-Print and fill out form: http://www.qatarairways.com/docs/pri...%20revised.pdf
-Send completed form with your PNR to: [email protected] to authorize them to deduct miles
-Once miles have been deducted, they'll email you to collect ticket at a ticketing office.
-You can call their 1-800 number to have it ticketed on the phone. No need to go to office in person.

This process should be better documented on qmiles.com/
