I used my soon to be expiring(Dec 1) krisflyer miles for a United flight but still have approx 19,000 expiring miles left. I dont really need a car or hotel and other ideas to use/save them?
Less than stellar value, but you can go on a shopping spree at Krisshop. Glenlivet 18 y/o for 33k miles.
If I have a singapore flight booked on AC and a austrian "connecting" flight booked on United, who do I contact to try and have my luggage sent all the way through to my Austrian flight?
