Today I am faced with a full F cabin on my flight from IAH-SFO. I know that the chances for Upgrade are slim due to it being full, therefore I checked the flight loads for todays remaining flights from IAH-SFO, and some of the later flights have open seats in F.

I know that upon checkin at the kiosk, we can often change flights, therefore, if I swap over the other flight, would I qualify for an upgrade assuming that there is an available seat ? Do we have the option for upgrade in this situation ?
