Which Airlines Operate Out of Chattanooga's Airport?

Seven carriers serve Chattanooga Metropolitan Airport (CHA): Southwest Airlines, Delta Air Lines, United Airlines, American Airlines, Allegiant Air, Spirit Airlines, and Frontier Airlines. Most offer one or two daily flights to major hubs or leisure destinations rather than extensive networks, so your routing options depend heavily on your destination and preferred carrier.

Understanding Your Airline Options at CHA

Chattanooga Metropolitan Airport handles roughly 2 million passengers annually across a modest terminal. The airport's size means fewer flights than Atlanta or Nashville, but ticket prices from CHA are often competitive because airlines use the airport primarily to feed passengers into hub cities like Atlanta (Delta), Charlotte (American), and Denver (United).

Southwest Airlines typically operates the most daily departures from CHA, with flights to Denver, Nashville, and seasonal leisure routes. Southwest's bag policy (two free checked bags) appeals to families, and flights often cost less than competitors on popular routes. Check current schedules at the airport's website, as routes adjust seasonally.

Delta Air Lines connects CHA to its Atlanta hub multiple times daily, which opens connections nationwide. This hub strategy means you can reach smaller cities through Atlanta more easily than through direct flights, though layover time adds travel duration.

United Airlines and American Airlines each maintain limited service, typically one to two flights daily to their respective hubs in Chicago and Charlotte. American's Charlotte connection works well for East Coast travel; United's Chicago hub suits Midwest and West Coast routing.

Ultra-low-cost carriers (Allegiant, Spirit, and Frontier) offer cheaper base fares but charge separately for checked bags, seat selection, and carry-on luggage. Allegiant, for example, often charges $25 to $35 per checked bag each way, which adds up for families. These carriers serve leisure destinations like Orlando and Las Vegas more frequently than business hubs.

Why CHA Flights Cost Less on Some Routes

Airlines compete fiercely for Chattanooga's underserved market. A round-trip to Denver on Southwest might cost $40 to $80 less than the same route from Nashville (BNA), 120 miles away, because Southwest has stronger competition pressure at CHA. Conversely, flights to smaller Southeast cities may actually cost more from Chattanooga than from Atlanta, since most regional carriers use Atlanta as their primary airport in Tennessee.

Booking direct flights versus connections matters here. Most non-hub routes from CHA require a layover in Atlanta, Charlotte, or Denver. A direct Southwest flight to Denver takes 2.5 hours; the same route with a layover adds 3 to 5 hours. Direct flights sell at a premium, but ultra-low-cost carriers almost never offer them from CHA.

Finding Current Schedules and Booking

The Chattanooga Metropolitan Airport website (flycha.com) lists all carriers and their current routes. Google Flights and other aggregators pull this information automatically, so you can compare fares across all seven airlines without visiting each carrier's website separately. However, ultra-low-cost carriers sometimes undercut Google Flights by $10 to $20 if you book directly with them, since they avoid paying commission to third-party sites.

Check the airport website before booking if you're planning travel more than two months out. Spirit and Allegiant occasionally announce or drop CHA routes based on seasonal demand, and routes can shift without much public notice.

TSA PreCheck and Security Lines at CHA

Chattanooga's airport is small enough that standard security lines typically process passengers within 10 to 15 minutes during off-peak hours (early morning or late evening). Lines can extend to 20 to 30 minutes during peak travel windows (early morning 6 a.m. to 8 a.m., evening 4 p.m. to 6 p.m.), especially on Friday and Sunday. TSA PreCheck is available and can cut screening time in half if you're a frequent traveler.

Parking and Ground Transportation

Parking at CHA costs $7 per day in the economy lot, $12 per day in the short-term lot, payable at exit. Rideshare pickup is free for 5 minutes; longer waits cost $2 per minute. The airport is 8 miles south of downtown Chattanooga. Some hotels offer free airport shuttles; ask when booking if you're staying near the airport or downtown.

International Travel Limitations

CHA does not have U.S. Customs facilities for international arrivals. If you're flying internationally from Chattanooga, you'll need to connect through Atlanta, Charlotte, or another hub city where customs operations exist. This makes most international routes require at least one layover.
