Anybody else have luck with upgrading ThankYou-booked flights with UA miles?
Hi all,
Interested in using my ThankYou Points to book UA international flights (fixed flight redemption award), and then using UA miles to upgrade to Business Class... I have one pal who's done this but wondering how prevalent success is in doing this?
I'm particularly interested in hearing from anybody who's managed to do this from CON48 to Singapore.
Thanks in advance!
