MightyTravel writes that there is a Delta coupon/ promo code available right now for domestic flights! Whoa! I have never heard of such a thing for Delta, but I tried it and it actually worked! It will save you a whooping 3%, but on the $330 flight that I was booking, that was about $10! So here you go and happy booking!
Amazing: Delta Promo Code For Discounted Flights!
What you need to do is enter the code in while you are searching versus when you are checking out. You can test it by first searching without the code for the flight you want, in my case it was $332. Then, I searched again with the event code and found the same flight for only $320 and change ~$11 difference. Here is where you enter the code.

Who knew? 3% might not get you some crazy deal, but hey it is something! Happy booking!
