Well. I have done it. Booking that way saved me miles for an extra flight on Delta. Round trip on Delta was 40,000 miles and one way was 25,000.I was then able to get a flight for my friend. 50,000 for 2 one way trips is not bad. otherwise going with Delta round trip would have cost 80,000 miles. Rediculous. I then used my AA miles which were expiring in a few months to get another one way for 12,500 each. Delta has become rediculous. In the future I will try flying AA. Now, should I get the airline insurance or do the miles get returned to me if I have to cancel in the future? The flight is not until next March.
