If you list some of the cities that you would like to visit with the miles it will be a lot easier to suggest an airline or alliance that will suit you best for example after getting the 100,000 BA miles from the credit card offer we were able to book 2 multi city tickets to asia going hong kong with stop overs in bangkok and singapore (only needing a 1 way flight between bkk and sin which is very inexpensive on discount asia airlines). There was no hassle throughout the process. We also booked a flight from JFk to the maldives with a stopover in Dubai using CO miles flying on emirates. The key to seeing availability was to sign up for a skywards account to see which dates were open. Once we were able to see avaliability we were able to call CO and tell them the flight numbers that were availiable and it was easy to confirm.
