Hi all,

This is my first time trying to use points through a Star Alliance partner to book a United flight. I had read that generally United flights you find through the United portal should be viewable through a partner's webpage, such as Air Canada. However, when I search for certain US domestic flights using Aeroplan points, I sometimes find no flights. For instance when I search for Boston/Portland flights Dec 27-Jan 2 with the Aeroplan Points button toggled, no flights show up as available. But when I do the same search in the United Airline portal, I see plenty of options. Did I just misunderstand how this works? Is there a way to 'find' these flights through Air Canada's webpage so that I can use some Aeroplan points? In searching for other guides online, it seems like they all refer to a previous version of how you searched with Aeroplan points (ie the 'Book with Aeroplan Points' button wasn't there yet).

Any help would be appreciated. Thanks!
