I've flown on Indy Air and they were a very nice airline. I would highly recommend them on the shorter routes that they fly. That not withstanding, you have a very valid concern about whether they'll even be around when you plan on traveling. They've survived this long, despite the rather critical forecasts. It's anybody's guess whether they'll be around by Aug/Sep or not. How much of a gamble are you willing to take with your money?
