This is a popular question. The answer depends on the airline and the number of miles you want to transfer. Most airlines, with the exception of Delta, allow for some sort of miles transfer, but usually limit the number of miles or charge a nominal fee. In some cases it is cheaper to buy a ticket, especially with today’s extremely low airfares.
Check with each airline regarding their policy for transferring miles.
All the best,
