Which airport do you prefer, and why? For some, it's the only option... ex: WN is only out of HOU and CO/UA is only out of IAH. For others, it's convenience. I live way closer to HOU than IAH and parking is a lot easier, at least for me. Most of my trips are on WN and if I need to go somewhere on AA I would have to connect at DFW. Eagle goes to DFW from HOU, so still easier for me. DL flies out of there as well. My last trip to ATL was NS out of Hobby.
