You have to call the Event Savers Desk to reserve those tickets as it cannot be done online. To get an idea of what the ticket will cost through Event Savers - go online at Airtran and select the date you want and hit continue to see the total price with all their taxes. From that price subtract 10% and that's what you will pay.

In addition to the discount with Event savers you also get an assigned seat (no add'l fee) and you are allowed one change (I used my change when my fare dropped on my return flight) and you can book your tickets and pay 10 days later - this locks in your fare...especially if you're waiting for your next pay day to buy your ticket.

I'm the planner in the group and super anal about it. It's so frustrating that people are stalling on their airline tickets so I know how you feel.
