I've a $330 balance with AirTran that expires on 5/24
That's from a flight I cancelled last year.

I would like to sell it for $200.

Because the balance cannot be transferred but only used towards a ticket purchase by me, that means that if you plan to fly anywhere within the US that AirTran flies I would have to book the ticket. For this to work, mutual trust is necessary. It can be any combination of tickets, not just one.

If interested send me a PM to discuss this further.

Thanks,
Theo
