FWIW, "DUT" stands for "Discretionary Upgrade Tool". It is a system for operational (and occasionally space-available) upgrades that are usually processed at least 29 hours before a flight.

Priority is based upon:
• Executive Club status (CIV score)
• Fare class
• Agency/industry discounts
• Date of booking
