CBX is about 18 to 20 miles from San Diego International, which is a 25 to 35 minute drive in normal traffic and can be considerably longer at peak times. Uber typically runs $35–55 on UberX before surge.
The important thing to understand first: your vehicle does not cross the border. Cross Border Xpress is a pedestrian bridge. You are driven to a terminal in Otay Mesa — on the US side, an ordinary San Diego trip — and you walk across the bridge into Tijuana International Airport yourself. No vehicle crossing, no vehicle queue at the border.
That one fact is why CBX works, and why getting there is a straightforward domestic transfer rather than an international expedition.
| # | Step | What happens | By |
|---|---|---|---|
| 1 | Drive to CBX | 18–20 miles to Otay Mesa, on the US side | 25–35 min |
| 2 | Ticket and bridge | CBX ticket plus a Tijuana boarding pass | 30–45 min |
| 3 | Mexican immigration | Cleared at the far end of the bridge | included |
| 4 | Inside TIJ | You come out at the airport terminal itself | — |
How CBX actually works
The Cross Border Xpress terminal sits in Otay Mesa, in the south-east of San Diego. From the US side:
- You are dropped at the CBX terminal.
- You present your CBX bridge ticket along with a boarding pass for a flight at Tijuana airport, dated within the permitted window either side of the crossing.
- You cross the enclosed pedestrian bridge — a walk of a few minutes.
- You clear Mexican immigration at the far end and come out inside Tijuana International Airport, at the terminal.
Coming the other way, you land at TIJ, walk across, clear US Customs and Border Protection in the CBX building, and you are in San Diego with your luggage.
What you need: a valid passport (and a Mexican visa or FMM where your nationality requires one), a CBX bridge ticket, and a TIJ boarding pass. The bridge ticket is bought separately from your flight — check the current price and the boarding-pass time window on the official CBX website before you travel, because both change.
Why people use it
Tijuana airport is a hub for Volaris and Aeroméxico, with direct flights across Mexico and onward to destinations that would otherwise mean a connection through Los Angeles or Mexico City. For travel into Mexico from San Diego, flying out of TIJ via CBX is frequently cheaper and faster than flying out of SAN — and the bridge turns what used to be a border-queue gamble into a predictable walk.
It also means a San Diego resident can reach much of Mexico without crossing a land border in a vehicle at all.
Getting there: the options
| Option | Time | Typical cost | Suits |
|---|---|---|---|
| Pre-booked van or car | 25–35 min | Fixed fare | Groups, luggage, early flights, fixed timing |
| Uber / Lyft | 25–35 min | $35–55 UberX | One or two people, flexible timing |
| Taxi | 25–35 min | Metered | No surge, but a long metered run |
| Public transit | 90+ min | A few dollars | Cheapest, impractical with bags |
| Drive and park | 25–35 min | Parking per day | Long trips where parking cost beats two transfers |
SAN to CBX starts at $79 in a sedan and $105 in the 14-seat van, with the same rates in the other direction and flight tracking included on CBX pickups. Downtown to CBX starts at $85. Indicative rates, confirmed before booking.
How much time to allow
This is where CBX trips go wrong. Three queues stack up, and only one of them is the drive.
For a departure from TIJ:
- Drive from SAN or central San Diego: 25–35 minutes, and up to an hour in weekday peak. Otay Mesa traffic is genuinely heavy at commute times.
- CBX terminal and bridge: allow 30–45 minutes to get through ticketing, the bridge and Mexican immigration. Busy periods run longer.
- TIJ check-in and security: as any airport.
A sensible total: be at CBX about three hours before your TIJ departure for an international flight, and two and a half for a domestic Mexican one. CBX publishes its own recommendation — follow theirs over any blog, including this one.
Coming into San Diego, build in time for US Customs and Border Protection at the CBX building. It is usually efficient, but it is a federal inspection point and queues happen.
When a booked vehicle makes sense
Rideshare to CBX is perfectly workable for one or two travellers with carry-ons and a flexible schedule. Book instead when:
You are flying early. Many TIJ departures are early morning, which means leaving San Diego at 4 or 5am. That is the thinnest part of the rideshare day and the worst time to discover no driver wants a run to Otay Mesa.
You are a group. Families and groups are a large share of CBX traffic. Five or more people plus luggage is two vehicles on the apps, and Otay Mesa is not a place where two separately-dispatched cars reliably arrive together.
You are coming back. A pickup at CBX after an international flight, with a hard-to-predict arrival time, is exactly the trip rideshare handles worst. A booked vehicle tracks the flight.
You want the price fixed. Otay Mesa is a long run from most of San Diego, and a metered or surged fare on a 20-mile trip at 5am can be unpleasant.
Mobility or car seats are involved. Accessible vehicles and fitted child seats are reserved, not summoned. Our ADA van carries a hydraulic lift; child seats are fitted before we leave.
A note on what we can and cannot do
We drive you to and from the CBX terminal on the US side. We do not cross the border, and you do not need us to — the bridge is the crossing, and you walk it. If you need a vehicle on the Mexican side after you arrive at TIJ, arrange that separately in Tijuana.
That division is the normal way CBX transfers work, and it is also what keeps the price sensible: your trip is a San Diego trip.
Frequently asked questions
How much is an Uber from San Diego airport to CBX? Typically $35–55 on UberX for the 18–20 mile trip in normal conditions. Early-morning and peak-hour surge can push it well above that, and five or more passengers will need more than one vehicle.
How far is CBX from San Diego airport? About 18 to 20 miles, a 25 to 35 minute drive in normal traffic. Allow up to an hour at weekday commute times.
Do I need a ticket to cross the CBX bridge? Yes. The bridge ticket is bought separately from your flight, and you must also present a Tijuana airport boarding pass within the permitted time window. Check current prices and rules on the official CBX site.
Does my driver cross the border? No. CBX is a pedestrian bridge. You are dropped at the terminal on the San Diego side and walk across into Tijuana airport yourself, so the vehicle never crosses.
How early should I get to CBX before my flight? Allow around three hours before an international departure from TIJ and about two and a half for a domestic Mexican flight, covering the drive, the bridge and Mexican immigration, then airport check-in.
Can I book a pickup at CBX coming back into San Diego? Yes, and it is the trip most worth booking. Arrival times after an international flight plus a border inspection are hard to predict, and a tracked booking waits where a rideshare request will not.
Dropped at the bridge, on time, for a fixed fare. Early-morning CBX runs and tracked return pickups, with room for the group and the luggage. Book your CBX transfer or call dispatch 24/7 on +1 (619) 863-3842.
