Found the perfect award on Continental.com. *A First to Europe and back. Exact flights I want. Goes all the way to the "Purchase Now" and then it fails with "One or more flights are no longer available for this request. Please begin your search again." Went back and searched for flights again... found same flights again, but same thing -- fails at the end. Three times, no luck. Why's CO lying to me? Anyone have a workaround? Will calling reservations be more successful?
