Upgrade on international award ticket
I'm 1K (and a Million Mile Flyer) but United tells me that if i book an international flight with miles, I can't be upgraded either complementary or with Plus Points. I also tried doing it on the website but was blocked there too. Apparently if it was domestic, I could be upgraded if i paid the taxes and fees with a Chase card. Not sure what's more ridiculous - that paying the tiny amount with a Chase card changes the result or that its only for domestic. Does anybody know a way around this?
