Hey FlyerTalk Family:
I'm a rookie to Star Alliance Upgrade Awards, and wanted to ask - are ANA flights booked under a United codeshare eligible for Star Alliance Upgrade Awards using MileagePlus miles?
Below is a pic of the ANA flights I'm looking at (all operated by ANA), but if I book through United, there's a $1K+ cost savings. The problem is then the long-haul flights aren't NH but UA codeshare, and I was hoping to use a *A Upgrade Award to go from Business to First. Will codeshare be okay or will that block me from going forward?
I read
United's FAQs which mention "Upgrades are valid only on participating Star Alliance carriers. Codeshare flights not eligible." ... but as UA and ANA are both *A, does that mean we're good?
Thanks for any guidance you can provide!
