Hello guys, I am kind of new on this. I need to book 2 tickets from PHX to SFO end of March, which need 50K total points. I only have 46K in my UA account. How can I make the difference? I have many SPG points, but the ratio from SPG to UA is 2:1, which I am not willing to do so. I also have 10K HHornor(i think it is 10:1). I also have 12K NWA points (but i dont think it can be transferred to UA)

The fare costs around 220$ RT, is that worth to redeem the points or just purchase it?

Can anyone help? Thanks a lot!
