Complimentary Upgrade using Miles
Going on a trip to Kauai in Sept with a friend. I bought my ticket so hopefully I'll get a comp upgrade since I'm 1k. I used miles from my acct to buy my friend's ticket since I have a Pres Plus MC. Last Jan I did the same thing for a trip and was advised to ask CO to change booking class to X class so my friend would be in line for an upgrade even though I used miles from my acct and it's my credit card acct. It worked and my friend got his upgrade.
I understood there was some glitch within CO which made this possible. Is that still the situation? Thanks
