1) Double Fare Rewards: Fly on purchased FC tickets and receive double fare rewards points plus any mileage. Available March 1 to March 31, 1999. No preregistration appears to be necessary.

2) Double miles extended through March 31 for Houston. Call 800-325-4815 and enter 23479 to preregister.

3) Double miles ends for Cincinnati, Dayton, and Philadelphia February 28th. Preregister as above for Houston (same numbers).

4) Through March 31st, double miles for St. Louis to Boston, Columbus, and Mexico City. Call 800-325-4815 and enter 23699 to preregister. I'm not certain if you connect through St. Louis that you'll get the points... I would think that would suffice, but one never knows.
