Airtran is offering $10 discount codes in conjunction with Little Debbie. One code per email address. Book by August 31 for travel August 1 through November 18.
It’s one discount code per email address, and the rules do say “Limit one (1) discount per person” though presumably in practice this means one $10 discount per reservation. I imagine you could get two codes, and book two one-way tickets instead of a roundtrip, taking $10 off each one-way (for a total discount of $20 roundtrip). The terms and conditions of the offer do not require roundtrip travel.
