Henry E. Rohlsen Airport Terminal

Gate 11 at STX skips TSA entirely for Cape Air hops

Henry E. Rohlsen’s Main terminal runs 10 gates in a single two‑story, 181,000‑sq‑ft building, but Cape Air’s gate 11 sits off to the side with no standard TSA screening for inter‑island flights. American, Delta, Spirit, and JetBlue all share the main post‑security holdroom, so once you clear the checkpoint you’re in the same compact space regardless of airline. If you’re mixing a mainland carrier with a Cape Air segment on one trip, you’re effectively dealing with two very different gate zones inside one small building.

Single standard checkpoint, zero TSA PreCheck

The terminal runs one TSA checkpoint with no PreCheck lane, and local guides recommend getting to STX at least 2 hours before departure. Check‑in counters can close 45–60 minutes before flights, and every departing passenger still has to clear U.S. Customs & Border Protection on the way out. Flightradar24 scores security at about 48%, so lines feel long whenever a couple of American, Delta, Spirit, and JetBlue departures stack up in the same hour.

Layout: short walks, two levels, shared gate area

The building’s 181,000 sq ft footprint means the walk from check‑in to the furthest mainline gate is only a few minutes, even if you stop upstairs to sit by a window. All 10 gates sit off one main concourse, with the four big carriers using the same general seating area and jet bridge positions. Cape Air’s gate 11 operates from its own corner, treating those small inter‑island flights differently from the screened departures heading to the mainland.

Amenities: basic seating, limited food and retail

Terminal facilities, food, and retail all hover around 48–51% in Flightradar24 reviews, which matches what you’ll see on the floor: basic seating, a few small counters, and not much in the way of full restaurants or branded shops. You won’t find a lounge, and there’s no catalogued sit‑down dining in the Main terminal. Build in time to eat in Frederiksted or Christiansted before you head out, because post‑security options at STX lean light snacks rather than real meals.

What regulars do at STX

Locals and frequent visitors follow the two‑hour rule and show up early even for morning departures with American or JetBlue, knowing Customs plus a single lane can bog down quickly. Inter‑island regulars deliberately route via Cape Air’s gate 11 when it fits the plan, using the no‑TSA flow there to dodge the main checkpoint on short hops. People who know the building also skip wandering for food, since nothing substantial is catalogued beyond small stands near the gates.

Watch out for the exit process and thin amenities

Villa Margarita flags that outbound Customs at STX makes even a 1:30 p.m. “domestic” flight feel more like an international departure, with one more queue after TSA. With terminal facilities rated around 50%, sitting through a delay can feel longer than the actual 35–40 minute flight up to San Juan. Power outlets are limited, and when two or three flights leave in the same 60‑minute window, seats near the American and Delta gate clusters go fast.

One last tip

Build the buffer: arrive 2 hours early, clear the single standard TSA lane and U.S. Customs, then camp near your exact gate because gate changes in a 10‑gate terminal happen close to departure and announcements can be easy to miss in the echo of that small Main concourse.
