Terminal T hosts 4 airlines. You'll find 3 dining options, 1 shop here.
Gate T3 sits less than 200 feet from the only TSA checkpoint
The Sioux Falls Regional Airport passenger terminal uses a single concourse, labeled Terminal T, so every flight on Allegiant Air, American Eagle, Delta, and United departs from the same side of the building. All check-in counters line the front hall on the ground level, and the lone security lane sits in the center. From check-in to the farthest gate usually takes under 5 minutes on foot, even if you walk slowly.
Delta and United counters stand closest to the terminal’s central entrance
Allegiant, American Eagle, Delta, and United share one departures hall, but the counter positions matter if you’re tight on time. Delta and United typically occupy the middle banks, with Allegiant and American Eagle toward the ends. Bag drop generally opens about 2 hours before the first morning departure, and the check-in area is fully inside the same building as arrivals, so there’s no shuttle or separate terminal to think about.
Red Stone Pizza Company sits just past security near the main gates
Once you clear TSA in Terminal T, Red Stone Pizza Company is the primary hot-food option on the secure side. Expect basic personal pizzas and slices in the roughly $10–$15 range, plus fountain drinks and canned beer. It’s close enough to most gates that you can watch boarding lines form while you eat, so grabbing food here usually works even during a 45-minute layover.
Marlin’s & Subway operate together before security near ticketing
Marlin’s & Subway sit pre-security along the check-in hall, within a 2-minute walk of all airline counters. Marlin’s covers diner-style plates at standard highway-exit prices, while Subway handles the usual footlong and 6-inch sandwiches. If you’re dropping a rental car or meeting family, this side is easier for a sit-down breakfast or lunch, since you don’t need a boarding pass to reach it.
AeroStay hotel breakfast area connects directly to the terminal via walkway
The AeroStay Hotel links to the passenger terminal with an enclosed corridor, so hotel guests can reach the lobby in under 3 minutes without going outside. The hotel breakfast area often functions as an extra spot for a quick morning coffee or pastry before heading to TSA. This is technically outside the secure zone, so you’ll still need to budget 10–15 minutes to eat and then clear security before boarding.
Gift shops line the post-security concourse near the gate cluster
Small gift shops sit on the secure side of Terminal T, within sight of multiple gates, carrying regional souvenirs, snacks, soft drinks, and basic travel gear. Prices run higher than downtown Sioux Falls, but bottled water, headphones, and phone chargers are easy to grab on the way to boarding. Stock leans heavily on South Dakota and Sioux Falls items, so it’s a straightforward spot for last-minute gifts.
No dedicated airline lounges operate at FSD’s Terminal T
There are no Delta Sky Club, United Club, or third-party lounges in the Sioux Falls Regional Airport passenger terminal. Power outlets line several seating clusters near the central gates, so many frequent flyers just camp near their airline’s usual parking spot. If you want a quieter corner, walk toward the least-used end gate; the walk is under 4 minutes from security and usually gives you more empty chairs.
Plan one extra snack stop if you’re landing late after 9:00 p.m.
Food and retail closing times in Terminal T often track the last departures, so late-night arrivals can find Red Stone Pizza Company and the gift shops winding down around the final bank of flights. If your inbound hits after 9:00 p.m., pick up something in your origin airport first. The terminal’s compact layout means you can carry that through the single concourse easily without worrying about a long walk.
