Terminal MAIN hosts 8 airlines. You'll find 3 shops here.
One terminal, eight airlines, and a single lounge define CHS
All flights at Charleston International run through the Main Terminal, so American, Delta, Southwest, United, JetBlue, Allegiant, Frontier, and Silver all share the same security checkpoints and concourses. The layout is compact enough that most gate-to-gate walks stay under 10 minutes, even when you land at one end and depart from the other.
Security for the Main Terminal feeds straight into the concourse area, so build a 25–30 minute buffer at peak morning bank times for TSA. With only one terminal in play, you never transfer between buildings or trains; you just clear once and walk directly toward your gate cluster for your airline.
The Club CHS is the only lounge in the airport, and regulars know it caps out at about 83 people. Access often runs through bank cards and lounge networks, and a YouTube review notes that eligible cardholders can also buy day passes when capacity allows. If you care about a quiet seat and an outlet before boarding, this lounge is your only real upgrade option in the Main Terminal.
Because there is just one lounge in the whole airport, Club CHS can fill up on weekday mornings when Delta and American run their business-heavy banks. If you land around 7:30 a.m. and want in, head there before coffee or food runs; past 9:00 a.m. on Mondays, travelers report the 83 seats often all in use.
On the food side, Chick-fil-A is the standout confirmed option inside the Main Terminal, usually serving breakfast biscuits before 10:30 a.m. and then chicken sandwiches and nuggets the rest of the day. Prices sit in typical airport range, with combo meals landing around a few dollars more than street pricing, so plan on paying a small premium for anything beyond a basic sandwich.
Since Chick-fil-A closes on Sundays nationwide, Sunday flyers at CHS should eat before arriving or plan on grabbing something at a generic snack stand near their gate instead. On weekday mornings, lines there can stretch 10–15 minutes between 7:00 a.m. and 9:00 a.m., so factor that into your boarding time if your flight starts loading 30 minutes before departure.
Retail inside the Main Terminal stays fairly limited, with only a small set of newsstand-style shops confirmed near the gate areas. Expect the usual bottled drinks, chips, and magazines, and plan to pay around $3–4 for water and $5–7 for basic packaged snacks. If you need a real meal or specific brand, do it in downtown Charleston or North Charleston before you head to the airport.
All airlines share the same arrivals level and baggage claim, so when you land on American, Delta, Southwest, United, JetBlue, Allegiant, Frontier, or Silver, you follow one main hallway to the carousels. Rideshare pickup zones sit just outside on the curb, and even in light traffic the walk from baggage claim to your Uber or Lyft spot runs under 5 minutes.
For timing, treat CHS like a small but busy outstation: for domestic flights on the Main Terminal airlines, aim to arrive 90 minutes before departure, and push that to 2 hours on Monday mornings or holidays. With one terminal, one lounge, and shared security, the best play is simple: clear TSA first, then decide if you want the Club CHS or a Chick-fil-A run before you wander to your gate.
