American comes out of ORD direct and you should be able to book at least 6 months out. Frontier also goes direct and can be booked on line. Air Tran is new coming out of MDW took over southwest gates I'm trying them this time so I'll let you know. Sometimes United will do a direct during peak seasons. You just have to keep checking til you see what you want. And as mentioned above they only fly certain days like Sun to Sun
