Terminal B

All Allegiant check-in runs through Terminal B

All Allegiant flights at SFB start at Terminal B check-in, even if your boarding pass later sends you to an A-side gate. The entire airline’s counter setup, bag drop, and TSA funnel sit in B, so the crowd spikes when Allegiant’s morning bank hits between roughly 5:00–8:00 a.m. Regulars talk about security lines stretching across the hall while the walk to the gates takes under 10 minutes once you clear.

Layout: one main hall, one shared checkpoint

Terminal B’s landside level holds Allegiant ticket counters along the front wall and the single main TSA checkpoint at the back. Past security, concourses branch left and right toward both B and A gates, with walking times generally under 5–7 minutes to most doors. There’s no separate lounge area or alternate checkpoint, so every Allegiant passenger filters through the same screening zone, regardless of gate printed on the boarding pass.

Check-in and security: build a real buffer

Reviews call check-in and TSA in B “rammed” and “chaotic” when three or four Allegiant departures stack around the same hour, especially on peak days. The airline might say 2 hours for domestic, but frequent SFB users talk about arriving 2.5–3 hours before early morning flights to stay calm. There’s no PreCheck-only checkpoint and no CLEAR lane here, so everyone joins the same serpentine lines in Terminal B’s main hall.

Coffee and quick food: Starbucks or local names

Starbucks sits in Terminal B and is the only big national coffee chain called out in Allegiant’s airport guide, which is why its line hits the doorway before 6:00 a.m. on busy days. If you want a branded latte before a 7:15 a.m. Allegiant departure, you queue here before walking toward A or B gates. Regulars swear by grabbing coffee in B once, then skipping back later crowds by heading straight to their gate afterward.

Dining after security: what to know

Immediately post-security in B you’ll see local and regional options such as Hollerbach’s and Zaza, along with Nature’s Table, Sanford Market, and Sanford Tap scattered along the concourse. Prices trend on the pricey side compared with downtown Sanford; think $11–$13 sandwiches and $8–$10 breakfast wraps. Feedback says food is fine but basic, and lines stack up closest to the checkpoint, so walking a couple of gates down usually shortens the wait.

Seating, crowds, and how regulars handle it

With all Allegiant passengers funneled through B, the gate clusters nearest the checkpoint fill first, leaving some people standing during peaks. Flyers on repeat routes say they drift 3–5 gates away from their departure, pick a quieter row of chairs, and walk back when boarding status on the screen flips to “Now Boarding.” Since the terminal is compact, that walk back rarely takes more than 3–4 minutes.

Shops and services: manage expectations

Terminal B doesn’t have a big lineup of branded shops; it leans on multipurpose spots like Sanford Market for snacks, drinks, and last‑minute toiletries. You’ll pay airport markups on basics such as $4 bottled water and $3–$4 candy. There’s no listed pay-per-use lounge or spa here, so once you’re past security, your options are seats, power outlets near gates, and the restaurants and bar areas like Sanford Tap.

Watch out for lines, not walking time

Skytrax reviews repeatedly mention long, slow TSA lines and a “disorganized” screening flow in Terminal B, while the walk from checkpoint to any gate runs under 10 minutes. That match with Allegiant’s own note that both terminals share this B-side checkpoint means your real risk is queuing, not distance. One practical move: arrive at least 30–45 minutes earlier than you normally would, clear security, grab Starbucks or Zaza, then move a few gates away from the checkpoint to find a seat.
