You must know something I don't about frequent flyer miles. A year ago we tried to make reservations for our 35th wedding anniversary to Hawaii. They told us that we were a few days past the 9 months lead time tht they allow for frequent flyer reservations so of course there were no flights available. We had to go 2 weeks later than we wanted. If you managed to get reservations for the convention all I can say is "congratulations"!
