Well this promotion expires before you start your classes, but if they do it again in the fall (which I really hope that they do!) it should help make the decision a bit easier.
(Can't belive that you have to decide between the service that you get on an Indy flight and on a UA flight; it's a no brainer that Indy service is better. IMHO)

This promo has saved serveral of my friends lots of money and kept them flying Indy, and in some cases got their family flying Indy.
