Hello.... I am a visitor from the AC/WS forums.

I find myself flying UA and I am wondering about upgrade options. My domestic and transboarder flying is split between various airlines and I have not had the opportunity to build *A status. So, I am wondering what options I have for upgrading on the following itinerary. Purchase at check-in? Gate? SWU (hopefully someone has a few exp. this month)?

04/19 - YYZ-ORD-OGG <Q>
The ORD-OGG we are in E+, but are keen on an UG

04/25 - OGG-SFO <V>

04/26 - SFO-YYZ <V>

Looking forward to your feedback!

Thanks

Steve
