Main Terminal fast food with a familiar Sonic logo
Sonic in Gulfport–Biloxi International Airport’s Main Terminal is one of three newer restaurant additions the airport brought in to modernize the dining lineup. It sits post-security, so you can grab a burger or tots after TSA without doubling back to the public side.
The menu tracks closely with a standard Sonic drive-in: burgers, chicken sandwiches, hot dogs, tater tots, and breakfast items, plus fountain drinks and slushes. Expect typical fast-food pricing for an airport, with meals landing in the roughly $10–$15 range once you add a drink and side.
Service speed varies by time of day, but this is still a quick-serve counter, not a sit-down bar. With only one main concourse at GPT, Sonic works as a catch‑all option if your gate changes from one end of Main to the other. You won’t walk more than a few minutes from any gate to reach it.
Sonic carries the usual drink gimmicks: flavored add‑ins, cherry limeades, and slushes, helpful in Gulfport’s humid weather when temps push into the 80s and 90s. If you tend to cut arrivals close, grab something portable like a breakfast burrito or a corn dog that you can finish at the gate instead of waiting on a tray of fries.
Rating-wise, it sits at 16 on our scale, which pegs it as a reliable national chain, not a destination. No major complaint pattern shows up in reviews, so assume standard Sonic quality: fine if you want fast food, skippable if you don’t.
Practical tip: if you land hungry on an evening flight and see shorter lines at the two other Main Terminal spots, eat first; Sonic can bunch up quickly when a couple of regional jets arrive within 20–30 minutes of each other.
