The QUP fares are the best deal in town. They are booked in A class of service (generally a subset of the F inventory), but it's a confirmed first class seat, with 150% mileage bonus, 150% EQM bonus, and a coach fare basis (Q) to turn in to your accounting department. On routes where UA is competing with WN the QUP fares can be amazingly low ($800 roundtrip transcon). Generally they are $100 penalty for change however, and some are as long as 21 day advance booking.
