There a number of dedicated FTers who fly out of Hartford, myself included. I flew 74 segments last year, over60 of them on AA.
Each terminal has it's pros and cons. The parking garage is pricey by local standards, a bargain by regional standards.
I usually know 10 weeks in advance whereI'm going, so I can routinely get RT to west coast for around $200 to $225. A typical trip involves changing ORD or DFW.
Please feel free to PM me for questions.
