I've been looking at the flights over the past two months for NYC-NCE using Saver Pass Economy Reward using 8/19/08 as outbound and 8/31/08 return. The reward availability calendar would appear with a range of dates, and I would click them through and check flight times, etc.

Over the past two days, when I attempt to find availability I now get the error message "Continental.com could not find any available flights for reward travel meeting your requirements". However the calendar clearly shows there is availability.

What I am doing wrong
