user: When will the Reduced Mileage Codes become available for December and January? December is less than a week away!
agent: There's not a set date or time. It's based on what seats are available. Please contact Reservations at 800-433-7300 for help with that.
user: They tell me that even though the seats are available, they don't have the codes to use. HELP!! !
agent: We're unable to make the code available. It's done automatically. You'll have to continue to check online or with Reservations.
user: So you agree that at this time Reduced Mileage Fares cannot be booked for December and January?
agent: Please check with our Reservations team and they'll provide clarification.
user: After 4 different agents, I FINALLY got someone who could book it--after I pointed out that it was on that it can be booked now. It seems the agents need some training on booking Reduced Mileage awards!
agent: We're glad they were able to take care of that with you! Thanks for working with them.
