As of today United systemwide upgrades can be applied on Continental flights, and full functionality should roll out on August 1. This is great news and opens up a lot more destinations for United flyers to use their systemwide upgrades on.
To determine Continental upgrade space you can either call Continental or check availability on their website. To check upgrade availability on their website, click on “advanced search” on the main search page, and then on the next page select “OnePass Reward Upgrade.”
On the next page just tick the box for the flights you want to upgrade.
Then the next page will display whether or not there’s upgrade space availability. If there is confirmable upgrade space, the booking code will show as “R” (as shown below).
If there isn’t confirmable upgrade space, there will be a message in red saying upgrade space is not available.
It’s simple as that!
