Remember the loo

OAK - LAX this morning. Water on way to airport. Grande starbux, southwest airline coffee, one oj..left it too late to pee. Agony taxing to the gate.

UA's free upgrades

So how does this work with all my regional and 500 mile upgrades? Do i ignore these, or do they give me a priority over the free upgrades.

Its a nice though UA, but please make it clear.
