1. Don't need to deal with transferring miles.
2. No award space availability and booking issues.
3. You earn miles miles on the flights flown which further reduces the redemption rate.
In addition to no award availability issues, you have a wide choice of airlines. So one can book the best option for a particular destination and not be bound by the mileage currency.
