Welcome to FT tlg664!
You will probably be able to fly, but I would guess that the airline's internal auditing department will catch the mistake and you will be asked to pony up for the free flight.
I would fly anyway and enjoy. If this is your frequent carrier, great they just gave you an unexpected perk. You certainly gave them an opportunity to correct their mistake.
