Flying from Chicago to Chattanooga means choosing between direct service on one carrier and connecting flights that often cost less but add three to five hours to your travel time. This guide covers what's actually available, the real trade-offs between price and convenience, and how to time your arrival for where you're staying in the city.
Southwest Airlines operates the only nonstop service between Chicago Midway (MDW) and Chattanooga Metropolitan Airport (CHA). The flight takes approximately two hours. Midway is 8 miles southwest of the Chicago Loop; O'Hare is 18 miles northwest, making Midway more convenient for most Chicago neighborhoods. Southwest's nonstop flights run daily, with typical departure times between 6:30 a.m. and 5:45 p.m., though schedules shift seasonally. Booking directly through Southwest or checking Google Flights for price tracking gives you the clearest view of fares, which typically range from $140 to $280 round-trip during off-peak periods and $200 to $400 during peak travel (March through May, September through October, and December).
The advantage of Midway is tangible: you board a Southwest flight and land at CHA, a regional airport small enough that you move through security and baggage claim in 20 minutes total. No connections, no missed bags, no sitting in a hub. For travelers staying downtown or in North Shore neighborhoods, the direct flight is worth a $50 to $100 premium over connections.
United, American, Delta, and Southwest all offer one-stop service, typically routing through Atlanta (ATL), Charlotte (CLT), or Memphis (MEM). These flights add 3 to 5 hours to your total travel time but often cost $40 to $120 less for round-trip fares. A typical itinerary involves a 1.5- to 2.5-hour layover, which is manageable but leaves no margin for delays.
Atlanta connections are the most frequent; Delta operates multiple daily flights from both Chicago airports through ATL to CHA. Charlotte offers similar frequency through American. Memphis (MEM) routing exists but appears less often in standard search results. These connecting flights occasionally undercut Southwest's nonstop fares by $50 to $100, making them genuinely cheaper options for budget-flexible travelers or those with scheduling flexibility.
The risk: if your first leg is delayed by 45 minutes, a tight connection becomes a missed flight and an overnight stay. Budget-conscious travelers should look for connections with at least two hours between arrivals and departures.
CHA is in East Brainerd, approximately 13 miles east of downtown Chattanooga. Rental cars, rideshare, and hotel shuttles are the primary options for onward travel. Ride-share from CHA to downtown runs $18 to $28 one-way depending on time of day and demand. Rental car counters are located in the main terminal; major agencies (Enterprise, Hertz, Budget, Avis) are present. A taxi stand operates outside baggage claim with flat rates: $35 to downtown, $38 to Riverfront, $40 to St. Elmo. If your lodging is in the Southside or St. Elmo neighborhoods, note that CHA is significantly closer to those areas than to Northshore; the fare difference is only $2 to $3, but the drive is noticeably shorter.
Some hotels in Downtown and Riverfront offer complimentary airport pickup. Check directly when booking.
Summer (June through August) and the winter holidays see the highest fares and most crowded flights. Spring break (mid-March through early April) and peak fall foliage season (mid-September through October) elevate prices. Winter weekdays (January through early March and November) typically offer the lowest fares, with round-trip tickets often available for $130 to $160.
Early morning departures from Chicago (6:30 to 8:00 a.m.) get you to Chattanooga by late morning, allowing arrival at most hotels by early afternoon. Afternoon departures (2:00 to 5:00 p.m.) land you in Chattanooga between 6:00 and 8:00 p.m., which works only if your hotel's check-in accommodates late arrival.
Southwest includes two checked bags free; United, American, and Delta charge $35 to $40 per bag for the first checked piece on basic economy fares. If you're traveling with luggage, the financial difference between Southwest and competitors widens. CHA baggage claim moves quickly; you'll have your bags 15 to 20 minutes after landing in most cases.
For under-three-hour travel time with no logistics headaches, Southwest's nonstop from Midway is worth its price premium if your budget allows $20 to $100 extra per round-trip ticket. For travelers flexible on arrival time or budget-constrained, connecting flights through Atlanta or Charlotte work, but book only if your connection has at least 90 minutes layover time. Avoid the temptation to book tight connections on the savings alone; missing a flight and purchasing a replacement ticket erases any savings immediately.
