San Antonio International Airport Terminal B Map (Most Up-To-Date)
San Antonio International Airport (SAT) Terminal B is a compact, linear concourse (B1–B8) with a single landside processing spine: upper-level curb → ticketing → one centralized security funnel → straight shot to gates and the food court. Despite being physically close to Terminal A within San Antonio’s primary airport complex, Terminal B functions like its own island once you clear TSA. The most important map skill is choosing the correct terminal and door before committing to a queue.

San Antonio International Airport Terminal B Map Strategy
- Treat Terminal B vs Terminal A as a binding choice: no airside connector, so verify terminal letter before curb drop-off, parking walk-up, or joining any TSA line.
- Enter Terminal B with a door-and-lane plan: PreCheck sits on the right side of the checkpoint, so hug the right flank early to avoid stanchion lockouts and wrong-lane corrections.
- Time mornings like a choke-point system: crowding concentrates between the entry doors, document-check podiums, and the TSA exit area near B1/B1A where gate queues spill backward.
- Solve parking and shuttle stress by mapping the exact level: shuttles drop on the upper departures level, but returns pick up on the lower arrivals level at the outer curb—standing on the wrong curb costs full shuttle cycles.

Terminal B remains the American + United side of SAT, with a single checkpoint feeding the B-gates concourse and the post-security food court (including Starbucks). The airside “hard wall” separation from Terminal A still defines every decision: clearing the wrong terminal forces a full exit and re-screen. Expect predictable pinch points at the checkpoint approach and at the first gates just beyond TSA during peak waves.

What is the shortest physical route from Terminal B ticketing to Terminal A ticketing, including the exact door/exterior crossing points?
No airside connector exists, so the shortest route is a landside (pre-security) walk on the upper Departures level using the covered connector between the two ticketing lobbies. Start at Terminal B’s upper-level ticketing counters, walk out toward the Departures curb-front, then follow the signed, covered pedestrian path that runs along the shared terminal frontage into Terminal A’s upper-level ticketing hall.
The fastest path stays on the Upper Level (Departures) the entire time to avoid baggage-claim crowds and crosswalk friction on the Lower Level. Use the continuous curb frontage as your alignment tool: Terminal A sits “upstream” on the same roadway, so you’re walking back toward the section of curb you drove past to reach Terminal B. If you accidentally clear TSA in either terminal, the recovery requires exiting to landside and re-screening at the correct terminal.
Where is the TSA PreCheck entrance in Terminal B, and what is the exact approach path from the main entry doors?
The TSA PreCheck lane in Terminal B is on the right side of the checkpoint as you face the queues. Enter Terminal B from the Upper Level (Departures) main doors into the ticketing lobby, then walk straight toward the centralized security area and immediately bias to the far-right edge before you reach the stanchions and the travel-document checker podiums.
Approach it like a “right-flank capture” so you don’t get trapped in the general lanes. From the lobby, keep the ticket counters behind you and aim toward the security funnel; as soon as the queue rails come into view, slide fully to the right-most entry point for PreCheck/CLEAR positioning. If you drift left into the general lanes, crossing back to the right is often blocked by the stanchion layout during peaks, costing several minutes and forcing an awkward cut across traffic.
Which specific corridor/queue segments in Terminal B become the primary bottleneck between entry doors and TSA during morning peaks?
The primary bottleneck is the security approach funnel where the open ticketing lobby collapses into the stanchioned queue in front of the travel-document checker podiums. Morning peaks compress arriving passengers from the main entry doors into a narrow “decision corridor” where people stop to identify PreCheck vs general lanes, creating sudden standstills and lateral blocking.
Crowding also spikes at two adjacent nodes that feed into that funnel. The first is the lobby-to-queue transition zone, where kiosk users and families pause near the checkpoint entrance and spill into the walking line from the doors. The second is the right-side lane-selection pinch: PreCheck is on the right, so travelers who drift left and then try to correct cause cross-flow conflicts exactly where the queue rails prevent easy movement. The result is a short stretch of stop-and-go congestion between the entry doors, the first stanchion opening, and the document-check positions.
From the closest on-airport parking option, what is the shortest walking path to the Terminal B check-in doors (identify the exact garage/lot entry and door)?
The Short Term Garage pedestrian bridge is the shortest walk to Terminal B check-in. It delivers you into the terminal on the mezzanine bridge entry, not directly into the ticketing floor.
Park in the Short Term Garage and follow signs for the pedestrian bridge into the terminal. Cross the bridge and enter the building at the mezzanine-level doorway, then take the escalator or elevator down one level to the Upper Level (Departures) ticketing lobby for American and United. Once you reach ticketing, orient to the curbside door signage; the Terminal B departures doors are the closest exterior reference point, with Door B6 signage commonly used as the curbside check-in landmark near the Terminal B frontage.
Where is the exact Green Lot shuttle drop-off point for Terminal B, and what is the walking path from drop-off to TSA?
The Green Lot shuttle drops passengers on the Upper Level (Departures) at the inner curb between Terminals A and B, a short lateral walk from Terminal B’s departures entry doors. This drop-off is designed to keep you on the ticketing level so you can enter and go straight to security without any elevator or escalator step.
After stepping off the shuttle, walk along the inner curb toward the Terminal B facade and enter through the Upper Level departures doors for Terminal B. Inside, continue forward through the ticketing lobby toward the centralized security checkpoint. As the queue area comes into view, decide your lane early—PreCheck is on the right—because the stanchions near the travel-document check positions make late lane changes difficult during peaks.
In Terminal B TSA, where is the crew/priority lane positioned relative to the regular lanes (left/right) as you face the checkpoints?
The PreCheck-eligible priority flow in Terminal B is on the right side of the checkpoint as you face the lanes. Terminal B’s layout inverts the common “PreCheck-left” muscle memory, so the fastest access to the priority/PreCheck side starts by hugging the right edge of the queue zone before you reach the document-check podiums.
If you enter the stanchioned area from the lobby and commit to the left-side general lanes, correcting to the right is often blocked by the queue rail geometry when it’s busy. Use the ticketing lobby as your setup space: walk toward security, then slide to the far-right entry point before the stanchions tighten and before you’re locked into the general queue.
Which specific gates and gate-zone in Terminal B are currently assigned to American vs United, as shown on the latest terminal map?
No fixed American-vs-United gate split exists on the current Terminal B map, so both airlines operate across the same Terminal B gate bank (B1–B8, plus the B1A area). Gate usage is operationally assigned and can rotate by time of day, aircraft turns, and irregular operations.
Terminal B is a single linear concourse, so the map shows one shared gate zone rather than two airline-dedicated piers. Use a physical anchor to orient quickly: the United Club sits mid-concourse between Gates B3 and B5, while the densest post-TSA compression often forms near the B1/B1A end right after the checkpoint. The most reliable confirmation point is the flight information displays immediately after TSA and again near the mid-corridor, since that’s where same-day gate assignments are posted and updated faster than static maps.
Where is the nearest coffee option to the center of Terminal B gates, and what is the exact walking route from TSA exit to that location?
Starbucks in the post-security Food Court is the nearest coffee option to the center of Terminal B’s gate corridor. It sits immediately beyond the security exit zone, before you fully commit down the linear gates walkway.
From the TSA exit in Terminal B, walk straight ahead into the post-security decompression area and enter the Food Court zone; Starbucks is inside that cluster rather than down at the far end of the gates. Use the B1/B1A side as your orientation landmark: the security exit feeds closest to that end, so you’re grabbing coffee before walking deeper toward mid-concourse anchors like the United Club between Gates B3 and B5. During peaks, ordering ahead reduces the common queue spill that blocks the Food Court edge.
Where are the closest restrooms after Terminal B security, and what is the shortest walking distance from TSA exit?
The closest post-security restrooms are immediately after the Terminal B TSA exit near the B1/B1A gate end. They’re positioned so you can reach them before walking down the main corridor toward mid-concourse gates.
From the TSA exit, step into the post-security area and scan the near-side walls and signage closest to the first gate cluster; the B1/B1A zone is the fastest landmark because it sits right at the security spill-out point. Additional restrooms appear farther down the linear concourse around the mid-gate stretch (often referenced around the B4–B6 area), but those require committing into the main corridor where boarding groups and seat clusters can slow movement. For the shortest distance, use the “immediately post-TSA” set before entering the gates walkway.
What is the exact curbside drop-off zone for Terminal B departures, and what is the shortest path from curb to the correct airline counters?
Terminal B departures drop-off is on the Upper Level (Departures) curb directly in front of Terminal B’s ticketing lobby doors. The shortest path is curb → nearest Terminal B departures doors → straight through the ticketing hall to the American/United counter line you see ahead.
Use Door B6 as the curbside landmark commonly tied to Terminal B services on the departures curb. From the curb, enter at the closest Terminal B-marked doors and keep moving straight into the ticketing space; counters sit on the same level, so no escalator or elevator is required from an upper-level drop. The main failure mode is being dropped too early at the Terminal A frontage because the curb is continuous—stay in flow past Terminal A and only unload once Terminal B signage and its doors are in front of you.
