I am booked to fly DEL to SFO on the 23rd of October in economy. I however wish to get an u pgrade using my fathers kris flyer miles (i am his nominee). He has 75700 miles in his account and i need 50,000 for an upgrade all the way to SFO from DEL.
I am wondering:
1. How do i transfer the miles to my account to get the upgrade?
2. What is the procedure if different from above?
3. I have 27,000 miles in my account already, so if i transfer the 75700 miles would that mean i have a total of 102700 miles?
4. Can i use krisflyer miles on other star alliance airlines particularly TAP and LH?
Any help would be highly appreciated.
