We are planning on going in Oct of 2005 are dates are not set yet. How soon or late should we buy airline tickets. We drove in May of 2004 and this time we want to fly. I have never bought airline tickets before and I am clueless. Do they ever give a discount for buying in a group? My sister, her two kids, my parents and me an my family of 4 are going together. Any advice would be great! Also one more thing. I live south of Chicago from everything I have read it is cheaper to go to Indy and fly out. One other option is Gary. I was just wondering how hard it would be to meet up with my family at the airport though if we fly out of somewhere different then them?
