CHA is a compact but efficient airport serving a metropolitan market of about 500000 residents. In the past it has suffered from proximity to major airports in Nashville and Atlanta but today 7 airlines service Chattanooga with a rather rapidly growing number of destinations. The airport is very clean with free Wi-Fi throughout and parking and security is superior. Low fare airlines have joined the legacy carriers so there is quite a nice selection of flights and fares. Sure saves time and headaches of leaving from larger airports.
