Booking United Flights With Global Premier Upgrades

Global Premier Upgrades, formerly System Wide Upgrades, permit upgrades without any miles or copay. The pre-merger United.com website had a search option for using a System Wide. The post-merger website has no comparable feature. This means users have to use the Advanced Search and search for fare classes W and V, the two cheapest fares that work with System Wides. Then there is no way to know if the upgrade will clear at booking. The best method for confirming upgrades at booking is making a reservation and then trying to apply the upgrade. The website will say if seats can be confirmed. If the flight is waitlist space only, cancel the reservation and try a different date. There’s no fee because you are cancelling 15 minutes into the 24 hour free cancelation window. United will put an authorization hold on the credit card used, so your available credit will be used up quickly.
