Think of the "rules" as "guidelines." Saturday night stay rule? Just show up at the gate for the flight you want to take, before the Saturday night. I would bet you they will just let you on the flight. Especially with a free award. If they ask you any questions, just say you have no idea about the rule. And again, don't make the mistake of calling res and asking them to make the change. They often will document your pnr (passenger name record in computer) to say they have advised you you can't do what you asked. Then your "I've never heard of that rule," will not work at the airport. They will say "But Mr. Jones, it says right in the record, you were advised you had to stay a Saturday night...I'm very sorry but you will have to follow the rules." Before you just head for the airport, be sure to check loads on flights of interest. Good luck, and remember the rules are just suggestions.
