I really like DFW as my home base. I live to the north of the airport, so I use the Park N Fly off-airport parking service as it's the most convenient. 15 minutes from my house to the lot. Early morning flights out on AA are not a problem because there are a large number of shuttles for morning travelers from the lot. I can get to the airport and hang out in the Admirals Club until my flight. There are 4 AC's at DFW, one in every terminal that AA uses (A, B, C, and D).
