Here is the anser to your Question "Can I Use Someone Else’s Airline Miles?" :

Yes, you can use someone else’s airline miles, but it depends on the airline's policy. Some airlines allow miles to be transferred to another person's account, though they may charge a fee for this service. Alternatively, many airlines let you book a flight for someone else using your own miles without needing to transfer them. This can be done by selecting the name of the person you want to book for during the reservation process. However, make sure to review the specific rules of the airline’s frequent flyer program to avoid any issues.
