Los Angeles LAX Airport: Definitive Terminal Transfer, Airside Walkways, Shuttle, and Connection Guide

Quick Summary

• Primary Update: Los Angeles International Airport (LAX) features continuous post-security airside connectivity linking all nine passenger terminals—Terminals 1 through 8 and the Tom Bradley International Terminal (TBIT / Terminal B). Passengers transferring between domestic flights, or connecting from a domestic flight to an outbound international flight, can walk between any gate in the entire airport complex without exiting the sterile zone or clearing Transportation Security Administration (TSA) checkpoints a second time.
• Transit Impact: The United States enforces strict non-sterile transit regulations for arriving international passengers. Travelers landing at LAX on overseas inbound flights—including carriers such as Air India, British Airways, Emirates, Singapore Airlines, Qatar Airways, ANA, and Lufthansa—must clear US Customs and Border Protection (CBP) passport control, collect all checked luggage at the arrival carousels, pass customs inspection, and re-deposit bags at airline transfer belts before re-clearing TSA security to reach onward domestic connections.
• Traveler Advice: Allocate a minimum connection window of 150 to 180 minutes (2.5 to 3 hours) for international-to-domestic transfers requiring border clearance and baggage re-check. For domestic-to-domestic connections utilizing the airside pedestrian corridors, budget 45 to 75 minutes depending on whether your gates are in adjacent terminals or opposite ends of the U-shaped terminal horseshoe.

1. Airport Architecture and Terminal Distribution

Los Angeles International Airport (LAX) is arranged around a central two-level, U-shaped roadway system known as World Way. Nine passenger terminals flank the perimeter of this horseshoe configuration: Terminals 1, 2, and 3 occupy the northern side; Tom Bradley International Terminal (TBIT / Terminal B) sits at the western apex; and Terminals 4, 5, 6, 7, and 8 wrap along the southern perimeter.

  (American)         (American/JetBlue)    (Alaska/Air Canada)      (United Airlines)

Understanding airline terminal assignments is critical to anticipating walking times and terminal transition points:

• Terminal 1: Exclusively serves Southwest Airlines for domestic and international departures, alongside select charter operations.
• Terminal 2: Operates as a shared check-in, baggage drop, and arrivals facility for Delta Air Lines and partner carrier WestJet.
• Terminal 3: Primary departure and gates complex for Delta Air Lines, featuring a unified security checkpoint, expansive Delta Sky Club, and direct airside bridge access to TBIT.
• Tom Bradley International Terminal (TBIT / Terminal B): Houses the vast majority of long-haul international carriers, including Air India, British Airways, Cathay Pacific, Emirates, Etihad Airways, EVA Air, Japan Airlines, Korean Air, Lufthansa, Qantas, Qatar Airways, Singapore Airlines, and Virgin Atlantic. TBIT also accommodates select widebody domestic and international departures for American Airlines and Delta Air Lines. The terminal includes the West Gates at Tom Bradley (Gates 201–225), a standalone midfield concourse connected via a subterranean walkway.
• Terminal 4: Main operational hub for American Airlines domestic and flagship transcontinental flights.
• Terminal 5: American Airlines secondary concourse, alongside operations for JetBlue and Spirit Airlines.
• Terminal 6: Hub for Alaska Airlines and Air Canada, with select gates utilized by regional partners.
• Terminal 7: United Airlines main concourse handling domestic trunk routes, transcontinental services, and international flights.
• Terminal 8: United Airlines and United Express regional jet operations.

2. Post-Security Airside Walkway Network

The completion of the post-security airside connector network links all nine LAX passenger terminals behind TSA screening. This allows connecting passengers on domestic flights to change terminals without exiting the secure zone, retrieving bags, or waiting in general security lines.

Segment                  | Physical Infrastructure       | Elevators / Escalators Required

Terminal 1 to Terminal 2 | Elevated Connector Bridge     | Level 3 concourse transition
Terminal 2 to Terminal 3 | Sky Way Secure Corridor       | Direct level walkway
Terminal 3 to TBIT       | Elevated West Bridge          | Level 4 concourse connector
TBIT Main to West Gates  | Subterranean Pedestrian Tunnel| Down via escalators, moving walkways
TBIT to Terminal 4       | Terminal 4 Connector Bridge   | Level 5 bridge over vehicle ramp
Terminal 4 to Terminal 5 | Underground Concourse Tunnel  | Level 2 ramp to tunnel corridor
Terminal 5 to Terminal 6 | Underground Concourse Tunnel  | Level 2 sub-level tunnel
Terminal 6 to Terminal 7 | Above-ground Enclosed Bridge  | Level 3 connector corridor
Terminal 7 to Terminal 8 | Continuous Concourse Pier     | Flat walking path, no grade change

North Side Routing: Terminals 1, 2, 3 to TBIT

Passengers transferring on the north side of the airport utilize the following paths:

1. Terminal 1 to Terminal 2: An enclosed pedestrian bridge links the eastern end of Terminal 1 to the departures level of Terminal 2. The walkway requires approximately 4 to 6 minutes of walking time.
2. Terminal 2 to Terminal 3: The Delta Sky Way facility provides an expansive, unified airside concourse corridor connecting Terminals 2 and 3 seamlessly. Walking time is roughly 3 to 5 minutes.
3. Terminal 3 to TBIT: An elevated post-security bridge links Terminal 3 directly with the north side of the Tom Bradley International Terminal concourse. Passengers walking from Terminal 3 enter TBIT near Gate 130 without changing floor levels. Walking time is 5 to 7 minutes.

TBIT Core to West Gates (Gates 201–225)

The West Gates concourse is located approximately 1,000 feet west of the main TBIT structure. To reach Gates 201 through 225:

• Locate the escalator bank near Gate 148 inside the TBIT main departures hall.
• Descend to the subterranean passenger tunnel.
• Utilize the series of moving pedestrian walkways spanning the length of the tunnel.
• Ascend via escalators into the multi-level West Gates concourse.
• Walking Time: Allow 12 to 18 minutes from the TBIT central Great Hall to outer West Gates. Add an additional 5 minutes if pushing strollers or carrying heavy carry-on luggage.

South Side Routing: TBIT, Terminals 4, 5, 6, 7, and 8

The southern concourses form an unbroken post-security chain:

1. TBIT to Terminal 4: The multi-level Terminal 4 Connector bridge departs the south end of TBIT near Gate 150. It carries passengers over the taxiway ramp directly into the upper concourse of Terminal 4 near Gate 40. Walking time is 4 to 6 minutes.
2. Terminal 4 to Terminal 5: An underground pedestrian tunnel connects the rotunda of Terminal 4 to the center of Terminal 5. Follow overhead signs reading "To Gates 50–59 & Terminal 5." Walking time is 4 to 6 minutes.
3. Terminal 5 to Terminal 6: A subterranean tunnel mirrors the T4–T5 connection, linking the gate area of Terminal 5 to Terminal 6 near the Alaska Airlines customer service counter. Walking time is 4 to 5 minutes.
4. Terminal 6 to Terminal 7: An above-ground enclosed walkway links the baggage re-check area and gate cluster of Terminal 6 to United Airlines' Terminal 7 concourse. Walking time is 3 to 5 minutes.
5. Terminal 7 to Terminal 8: Terminals 7 and 8 form a continuous architectural wing. Walking between the Terminal 7 rotunda and the regional jet gates of Terminal 8 takes 2 to 4 minutes along a level concourse pier.

3. Walking Times and Inter-Terminal Distance Matrix

The following matrix provides realistic airside walking times between every major terminal cluster at LAX for an unencumbered traveler walking at a standard pace of 4.5 km/h (2.8 mph).

4. Landside Transit: LAX Route A Shuttle vs. Walking the Horseshoe

While airside walking is standard for sterile transfers, passengers arriving from international flights, travelers carrying cumbersome luggage, or those transferring between opposite ends of the horseshoe (such as Terminal 1 to Terminal 7) can use landside transport options.

Transit Mode     | Operating Hours | Frequency    | Cost  | Route & Boarding Points

Airside Walkways | 24 Hours Daily  | Continuous   | Free  | Post-security corridors linking T1–8
Route A Shuttle  | 24 Hours Daily  | 10–12 mins   | Free  | Lower/Arrivals Level blue curbside
Horseshoe Walk   | 24 Hours Daily  | Continuous   | Free  | Upper/Lower curb pedestrian paths

Route A (Airline Connection) Shuttle

LAX operates the complimentary Route A Shuttle, a dedicated curbside bus circulating counter-clockwise around the central terminal horseshoe.

• Boarding Locations: Located on the Lower / Arrivals Level curbside outside each terminal. Look for overhead blue columns and signs marked "LAX Shuttle / Airline Connections."
• Operating Schedule: Runs 24 hours a day, 7 days a week, 365 days a year.
• Headway: Departs every 10 to 12 minutes during daytime and peak evening hours (05:00 to 01:00); every 15 to 20 minutes during overnight hours.
• Travel Direction: Shuttles navigate counter-clockwise: Terminal 1 → Terminal 2 → Terminal 3 → TBIT → Terminal 4 → Terminal 5 → Terminal 6 → Terminal 7 → Terminal 8 → Terminal 1.
• Transit Duration: Riding from Terminal 1 to TBIT takes approximately 6 to 9 minutes. Riding from TBIT to Terminal 1 requires completing the full loop around the southern terminals, taking 15 to 22 minutes depending on roadway traffic congestion.

Walking Landside Along World Way

Travelers can also walk outside along the curbside sidewalks of World Way.

• Upper Level (Departures): Offers wider pedestrian sidewalks, fewer vehicle exhaust emissions, and direct access to ticketing and TSA security lobbies.
• Lower Level (Arrivals): Convenient when exiting CBP customs or baggage claim carousels, but experiences heavier vehicular fumes and crowded crosswalks.
• Crossing the Center: Marked pedestrian crosswalks allow passengers to cut across the central median parking garage access roads (e.g., walking directly across from Terminal 1 to Terminal 7, or Terminal 2 to Terminal 6). Crossing through parking structures P-1, P-2, and P-7 saves up to 10 minutes compared to walking the full outer perimeter sidewalk, but requires navigating elevator banks and garage driving lanes.

5. International Arrivals and CBP Baggage Re-Check Procedures

The United States maintains no sterile transit. Arriving international travelers cannot stay on the aircraft or bypass border controls, even if their connecting flight departs from the exact same terminal. Every international passenger must execute the following sequential clearance procedure.

[Step 1: Deplane & Follow Overhead "Arrivals / US Customs" Signs]
      |
      v
[Step 2: Enter CBP Federal Inspection Services (FIS) Hall]
      |--> Non-US Citizens: Standard Visa / ESTA Inspection Lanes
      |--> US Citizens & LPRs: Dedicated Passport Control E-Gates
      |--> Registered Travelers: Global Entry Kiosks & Mobile Passport Control (MPC)
      |
      v
[Step 3: Collect Checked Bags from Assigned Carousel in Baggage Hall]
      |--> Mandatory even if baggage tag displays onward domestic final destination
      |
      v
[Step 4: Clear US Customs Agricultural & Security Exit Gate]
      |
      v
[Step 5: Deposit Luggage at Dedicated Airline Connecting Flights Re-Check Belts]
      |--> Turn immediate left upon exiting CBP doors into public greeting lobby
      |--> Delta, American, United, Alaska transfer desks accept tagged luggage
      |
      v
[Step 6: Proceed to Onward Departure Terminal]
      |--> Take TBIT TSA Checkpoint to use Airside Connector Bridges, OR
      |--> Take Route A Shuttle / Walk Landside to departure terminal TSA checkpoint

Detailed Clearance Walkthrough

1. Deplaning and Concierge Routing: Upon arrival at TBIT or the West Gates, follow the sterile glass-enclosed corridors leading downward to the Federal Inspection Services (FIS) facility on the basement level of TBIT. Arriving at a remote gate or West Gates requires traveling via the underground sterile corridor.
2. Passport Control: Pass through primary inspection. Travelers with Global Entry use facial recognition biometrics and proceed directly to baggage claim. Travelers with the US Mobile Passport Control (MPC) app access designated priority lanes. Travelers with standard B1/B2 visas, non-immigrant work visas (H-1B, L-1), or ESTAs proceed to general officer inspection counters.
3. Baggage Claim: Proceed into the international baggage claim hall. Locate your flight number on the baggage information display monitors. You must retrieve all checked baggage from the carousel. Airlines cannot transfer baggage through US border control on your behalf.
4. Customs Clearance: Exit the baggage hall through CBP customs inspection. Hand your declaration documentation to officers if flagged, or proceed through the general green exit channel.
5. Connecting Baggage Re-Check Desk: Immediately after passing through the automated sliding double-doors exiting customs into the public arrival lobby, look to your immediate left. You will find dedicated airline transfer desks staffed by major domestic airlines (Delta Air Lines, American Airlines, United Airlines, and Alaska Airlines):
   • If your luggage is already tagged to your final onward destination (e.g., showing a bag tag reading LAX - ORD or LAX - JFK), simply hand the bags to the baggage handler at the re-check belt. The agent will scan the barcode tag and place the bag onto the airport transfer conveyor system.
   • If your bags are not tagged through to your final destination (for example, if you booked two separate tickets across unaligned airlines), you cannot drop your bags at this desk. You must transport your luggage to your departing airline's main departures lobby ticket counter in their respective terminal.
6. Re-clearing TSA Security: Once bags are dropped, you have two choices:
   • Option A (TBIT TSA Checkpoint): Ascend to Level 4 of TBIT, pass through TBIT TSA security screening, and use the airside connector bridges to walk to Terminal 3 (Delta), Terminal 4/5 (American), or Terminal 6/7/8 (Alaska/United). This keeps you indoors in air-conditioned comfort.
   • Option B (Terminal Direct): Walk landside along the sidewalk or board the Route A shuttle to your onward terminal, then clear TSA security at that terminal's departures checkpoint. This is recommended if connecting to Terminal 1 (Southwest) or Terminal 7/8 (United) to avoid long airside walking treks.

6. Minimum Connection Times (MCT) Reference Table

Minimum Connection Times at LAX depend strictly on passenger nationality, customs clearance requirements, and terminal locations. The table below outlines airline-mandated MCT minimums alongside realistic real-world buffers recommended by Passage Wire editors.

7. TSA Security Checkpoints and Expedited Screening Programs

Because international arrivals and certain landside terminal changes require passing through security, navigating TSA checkpoints efficiently can make the difference between making or missing a connection.

Terminal 8 | No Checkpoint      | Checkpoint in T7   | Checkpoint in T7| Direct concourse walk

• TSA PreCheck: Dedicated PreCheck lanes operate across Terminals 1, 2, 3, 4, 5, 6, 7, and TBIT. Eligible passengers do not need to remove shoes, light jackets, 3-1-1 liquids, or laptops.
• CLEAR Plus: Available at Terminals 1, 2, 3, 4, 5, 6, 7, and TBIT for subscribers, escorting passengers directly to biometric verification before the physical screening checkpoint.
• Liquid and Carry-On Rules: Arriving international passengers who purchased duty-free liquids (such as perfumes, spirits, or wine) exceeding 100 ml (3.4 oz) in overseas airports must pack these items into their checked luggage before handing bags over at the connecting flight re-check counter. If duty-free bottles remain in carry-on baggage at the TSA checkpoint, they will be confiscated unless enclosed in an untampered Secure Tamper-Evident Bag (STEB) with a verified receipt from within the preceding 48 hours.

8. Practical Traveler Logistics and Connection Checklist

Execute this operational checklist to ensure a smooth connection across LAX terminals:

Before Departure

• Verify Through-Checked Baggage: Confirm at your origin departure desk that baggage claim tags show the final airport code, not just LAX.
• Review US Entry Documentation: Ensure your passport is valid for at least six months beyond your departure date, and confirm your approved ESTA or valid US non-immigrant visa (B1/B2, C-1 Transit, F-1, H-1B).
• Download Airline & Border Apps: Install the Mobile Passport Control (MPC) app on your mobile device to expedite customs processing. Download mobile boarding passes for both flight legs.

On Arrival at LAX

• Identify Connecting Gate: Check flight information display monitors or your airline app upon deplaning to confirm the departure terminal and gate for your onward flight. Gate reassignments occur frequently at LAX.
• Complete Border Processing: Follow signs strictly to US Customs and Border Protection. Do not stop at restrooms before immigration queues during peak arrival banks.
• Retrieve Baggage Immediately: Proceed directly to your carousel. Collect all personal bags and confirm bag tag names before walking through customs.
• Drop Bags at Transfer Desk: Drop tagged bags at the connecting counter to the left of the customs exit. If traveling on separate tickets, verify if you must walk luggage to the originating airline ticket counter.
• Choose Transfer Mode:
  • If connecting to an adjacent terminal, use the post-security airside connector network after clearing security.
  • If connecting across the horseshoe with heavy bags or young children, proceed to the Lower/Arrivals Level curb and board the complimentary Route A shuttle bus.

9. Frequently Asked Questions (FAQ)

Do I need a visa or ESTA if I am only changing planes at LAX to an international flight?

Yes. The United States does not offer sterile international transit lounges. Every passenger arriving from a foreign airport must clear US Customs and Border Protection. Citizens of Visa Waiver Program (VWP) countries must hold an approved ESTA authorization. Citizens of non-VWP countries (including India, China, the Philippines, and most African and Latin American nations) must hold a valid US visitor visa (B1/B2) or transit visa (C-1).

Can I walk between all nine terminals at LAX without going through security again?

Yes. If you are already inside the secure area (for instance, arriving on a domestic flight or having already cleared TSA security), you can walk between all gates from Terminal 1 through Terminal 8 and TBIT entirely airside. The complete network of enclosed pedestrian bridges and underground concourse tunnels is located post-security.

How do I get to the West Gates (Gates 201–225) at Tom Bradley International Terminal?

The West Gates are accessed via an underground pedestrian tunnel equipped with moving walkways. In the main TBIT Great Hall, locate the escalator descent near Gate 148. Ride the escalators down, travel through the tunnel, and ascend into the West Gates building. Allow 12 to 18 minutes of walking time from the central TBIT terminal area.

Where is the luggage re-check desk for connecting flights at TBIT?

The connecting flight bag drop desks are located immediately to your left after you exit the CBP customs inspection doors into the public arrival greeting lobby on the Lower / Arrivals Level of TBIT. Major domestic airlines—including American, Delta, United, and Alaska—maintain staff and baggage induction belts here.

Is the LAX Route A shuttle bus free to use?

Yes. The Route A shuttle is completely free of charge and requires no ticket, transit pass, or boarding pass to ride. It operates 24/7 along the Lower / Arrivals Level curbside, arriving every 10 to 12 minutes.

What should I do if my incoming flight is delayed and my connection window shrinks?

If your inbound flight is delayed, notify the flight attendants prior to landing. At the gate or upon clearing customs, visit your onward airline's customer service desk immediately. If both flights were booked under a single reservation or interline ticket, the operating carrier is required to rebook you on the next available onward flight without rebooking fees. If you booked two separate tickets independently, the onward airline treats late arrivals as a no-show; contact their reservations desk immediately to request flight re-accommodation under their flat-tire policy rules.
