Cross Border Xpress (CBX): The San Diego ↔ Tijuana Airport Bridge

If your flight is at Tijuana International Airport (TIJ) and you're coming from San Diego, you don't need to cross at San Ysidro or Otay Mesa. Cross Border Xpress (CBX) is a private 390-foot pedestrian bridge that connects a US-side terminal in Otay Mesa directly to TIJ — passport check, customs, the works, in 15-30 minutes. It's the secret weapon for anyone flying out of TIJ from the San Diego area.

The 30-second answer

• What it is: A pedestrian bridge over the border connecting an Otay Mesa terminal to the TIJ airport.
• Cost: ~$32-42 USD one way; ~$52-68 USD round-trip (cheaper bought 30+ days ahead).
• Hours: 24/7.
• How long: 15-30 minutes total crossing time.
• Eligibility: Southbound, cross up to 24 hours before your TIJ departure; northbound, within 2 hours after your flight lands.
• Why use it: TIJ has cheaper Latin America flights than SAN. CBX makes TIJ practical for San Diego travelers.

What is CBX?

Cross Border Xpress is a private 120-meter (390 ft) pedestrian bridge over the US-Mexico border, connecting a dedicated terminal building in Otay Mesa, California to the international side of Tijuana International Airport. It opened in December 2015; since December 2025 it has been owned by Grupo Aeroportuario del Pacífico (GAP), the operator of Tijuana's airport itself.

CBX is only for ticketed TIJ travelers. Southbound, you can cross up to 24 hours before your TIJ departure; northbound, you must cross within 2 hours after your flight lands. You can't use it as a general border crossing — you must have a boarding pass or e-ticket.

Why use CBX instead of driving through Otay Mesa?

Three big reasons:

• Time. Driving from San Diego to TIJ via Otay Mesa means: drive to border (~30 min from downtown SD), wait in northbound border queue going home if you're picking up (1-3 hours), navigate Tijuana traffic to the airport (15-30 min depending on construction). Total: 2-4 hours of margin needed for a flight. CBX: ~30 minutes.
• No Mexican car insurance needed. You're a pedestrian, so no Mexican liability policy required. See our rental car guide for the alternative.
• TIJ has cheaper Latin America flights. Many direct flights to Mexico City, Guadalajara, Cancún, and connections onward to Latin America depart TIJ at significantly lower fares than the US-side equivalents. CBX is what makes those fares accessible to San Diego travelers.

How to use CBX, step by step

Going to Mexico (US → TIJ)

1. Buy your CBX ticket online in advance at crossborderxpress.com. Tickets are valid for a year, and advance purchase is discounted up to 20% — the best price kicks in at 30+ days out. Last-minute tickets run $5-6+ more per direction.
2. Drive or get dropped off at the CBX terminal at 2745 Otay Pacific Drive, San Diego (Otay Mesa). The terminal has short-term and long-term parking; long-term is fine for multi-day trips.
3. Check in for your flight at the CBX terminal. Most major airlines flying out of TIJ have check-in counters on the US side — drop your checked bags here. Volaris, Aeroméxico, VivaAerobús all participate.
4. Show your passport, boarding pass, and CBX ticket to enter the bridge. The walk over takes 5-10 minutes.
5. Clear Mexican immigration and customs on the TIJ side. Faster than typical Mexican border crossings — they're set up for flight throughput. Get your FMM tourist permit if you'll stay more than the border-zone time/distance.
6. You're in the TIJ departure area. Proceed to gate.

Coming from Mexico (TIJ → US)

1. Land at TIJ. Get your checked bags.
2. Walk to the CBX entrance within TIJ — clearly signed.
3. Show your passport, boarding pass, and CBX ticket. Don't linger in the airport — northbound crossings are only allowed within 2 hours of your flight landing at TIJ.
4. Cross the bridge to the US-side terminal.
5. Clear US customs and immigration at the CBX terminal. Usually far faster than Otay Mesa's vehicle queue, though holiday peaks can back it up.
6. Exit into Otay Mesa. Pre-arranged ride, taxi, Uber, parking pickup, or rental car at the terminal.

Pricing

"Advance purchase" means buying ahead of travel — the discount runs up to 20% off and is largest at 30+ days out. Family packs come in 4-, 5-, and 6-person sizes. Prices change often; the exact current rate is at crossborderxpress.com. Round-trip is the obvious better deal if you know your return date.

Parking and getting there

The CBX terminal at 2745 Otay Pacific Drive has both short- and long-term parking lots:

• Short-term: roughly $5-10 for drop-offs and quick pickups.
• Long-term: daily rates start around $15, and the 6+ day discount brings it as low as ~$14/day — reservable online. Still cheaper than airport parking at most US airports.
• Uber/Lyft/taxi: Both companies serve the terminal. Typically $25-45 from downtown San Diego, depending on demand.
• Shuttles: Several private shuttle services from San Diego hotels and the airport — useful for groups.

No bus stops at the terminal door, but MTS routes 905 and 909 (connecting from the Iris Avenue Trolley station) stop at Siempre Viva Rd & Britannia Blvd, about a 10-minute walk from the terminal.

Eligibility and FMM

You need:

• A passport (book or card). NEXUS/SENTRI cards speed up US re-entry but don't replace a passport for Mexican immigration.
• A confirmed flight at TIJ. Southbound, you can cross up to 24 hours before your departure. Northbound, you must cross within 2 hours after your flight lands.
• A CBX ticket — purchased online or at the terminal.
• An FMM if your Mexico trip will be longer than the border-zone time/distance limits. See our FMM guide. Mexico is transitioning the FMM to a digital format, and filling it out online before crossing is now the standard move.

Practical tips

1. Build in buffer time. CBX is fast but unfamiliar. Allow 90-120 minutes from your CBX-terminal arrival to your boarding pass time on first-time use. After you've done it once, 60 minutes is plenty.
2. Check in for your flight at the CBX terminal, not later. Drop checked bags. By the time you reach TIJ, you're walking to the gate.
3. Buy your CBX ticket as early as you can. The advance-purchase discount runs up to 20% (best at 30+ days out), and you skip the terminal kiosk line.
4. Tickets are valid for one year from purchase — so there's no reason to wait, and every reason to buy early.
5. Family packs save real money for groups of 4-6 — significantly cheaper than buying individual tickets.
6. If your flight is canceled or rescheduled, you usually don't need a reissue — tickets are valid for a year, so just cross once your new flight qualifies.

Bottom line

CBX makes flying out of TIJ a sensible choice for anyone in the San Diego area. The price is modest, the time savings vs driving Otay Mesa is enormous, and TIJ's cheaper Latin America flights frequently pay for the CBX ticket many times over. Buy your ticket early, build in buffer time on your first trip, and use the airline check-in at the CBX terminal — that's the whole playbook.
