Cross Border Express is Great, But It Can Be Tricky (Travelogue)


It’s time to kick off this Mexican travelogue with a look at how I got across the border in the first place. None of my flights ever touched the United States. Instead, I decided to go down to San Diego and use Cross Border Xpress (CBX) to walk across into Tijuana and fly domestically from there.

My parents were in town visiting, and they were miraculously heading to San Diego. So they graciously decided to get up early and drive me down to CBX. With my flight leaving at 10:45am, I wanted to get there two hours earlier since I didn’t know what to expect. That meant leaving at 6:45am for the two hour drive.

We pulled into the CBX terminal area at about 9am. There is a ton of construction going on around CBX with new light industrial buildings and a whole economy growing up around the airport. I imagine that the airport and CBX are the catalyst for this. CBX has a surprising number of parking lots, but they are all expensive. That was my biggest complaint about the entire experience.

I saw nothing less than $20 when booked in advance. Street parking can’t be reserved in advance, but it’s still $15 a day. For the 10 days I’d be gone, this wouldn’t make any sense. Besides, I drive a Hyundai and they say to not leave Kias and Hyundais there since people steal those more often.

The terminal itself is small, and there is a tiny check-in area for each of the Mexican airlines on the US side, and I guess that’s to print boarding passes, make changes, etc. You don’t check bags until later.

I didn’t need that, so I went toward the middle where there was an electronic gate.

Here I had to scan my CBX ticket followed by my boarding pass. The airlines will sell you tickets that include the CBX fee, but I found that was more expensive than just booking direct with CBX. I couldn’t find any benefit to booking through the airline other than the slight additional convenience of it all. Pass.

After clearing that electronic gate, I walked into a room that looks like it’s used for some sort of US security, but it’s empty and doesn’t seem to have been used in some time. I just kept walking up an escalator to the bridge. This is the best view I could get looking out at the border fence, because the rest of the windows on the bridge are frosted.

As you can tell, it was a bit of a walk over the border, but when I got there… there was a selfie spot clearly marked. Naturally, I obliged.

After crossing over the fence, I finally got over to the CBX checkpoint on the Mexican side where they make sure you have everything you need. I pulled out my CBX ticket, my boarding pass, and more. This is considered a land crossing, so it’s different than a flight. And since I would be staying for more than a week, I needed to fill out the LMM form and then pay about $50. This was a pain, but I got it done in advance.

I walked up and showed them my passport, my form, and then the receipt for payment. But the woman there told me that this was the wrong receipt. At least I think that’s what she said, because this was a Spanish-only conversation, and despite speaking Spanish decently, I didn’t know all of the words she was using. She told me to go look in my phone for a different receipt. We couldn’t find it. Then another guy came up, and he eventually found it. But of course, it has to be printed.

So, the woman told me to email an address, and then she could print it. I did that, but it wasn’t showing up in her email… and that’s when she realized that the internet was down on that computer and it couldn’t be fixed. So she want to another computer, but that wasn’t connected to the printer. Finally, she had me email it to another person who was in an admin office, and she printed it out for me. That was ridiculous, but kudos to those people for going above and beyond to help. The customer service was excellent.

With that out of the way, I went through Mexican immigration. I found it all very confusing. I went to the first person who called me, he looked through everything, then took me over to a different agent who… did something? I then passed through and had to put my bags through the x-ray for customs scanning.

Finally, I was on the other side.

This is where I would have checked bags if I had any, but instead I went straight to the very grand and very empty security line. Having finally passed through about half an hour after I started the whole thing, I could take a minute and breathe. That was a lot, but it really would have been pretty simple if I had printed out the right receipt. It just requires a fair bit of prep work for your first time through.

Now I was in the Tijuana airport, and I was ready to get going, but I had some time to kill. That, of course, will be covered in the next post when I finally take to the skies on my first airline of the trip, Viva.

As a side note, my return at the end of the trip into the US was a very similar process, just in reverse. I would absolutely feel comfortable arriving 1.5 hours before departure instead of 2 and possibly less than that.

    The cross border express seems like a good idea, ive heard San Diegans (is that right?) Say you dont save as much as you’d think flying out of Tijuana however.

    Still street parking for an airport is a very out of this world idea.

    1. Brett Avatar

      Mike – I found it saved a lot of money, but more importantly there is just a far better schedule available out of Tijuana than San Diego. It’s not even close. This month, Alaska has 1x daily to both Cabo and Puerto Vallarta while Southwest has 4x weekly to Cabo. That’s it. From Tijuana, there are 35 destinations in Mexico, most on Viva and Volaris but also Mexico City options on Aeromexico and Mexicana. There are also flights that operate throughout the day instead of the usual morning-south, afternoon-back rotation from the US. It’s no contest.

    Assuming your folks had their own (personally owned) set of wheels and didn’t just fly WN/AA in, all I’ve gotta say is, what a SET of parent! I guess in their gleaming eyes, kids never leave the nest… Every time I go down there, I don’t get hit by the policia turistico in Ensenada or Rosarita, but consistently am hit for bribes either south of Brown field, or in the last 1.5 miles south of the main San Ysidro crossing. The going rate for the bribes is 2.5-4x Juarez, 3-5x Mexicali, and infinitely more than San Luis del Colorado–i.e. ZERO bribes there!

    Anyway, now I only walk to TJ…no bribes, ever…

      kiosreajoshi – Nobody is driving into Mexico. That’s the point of Cross Border Xpress, it’s all on the US side.

    Not related to this post, but I had an idea for a future post: a lot of people are saying international traffic to/from the US has declined a lot since Trump took office. Not to have a political discussion (please not), but I love facts. Since you have access to a lot of data sources: is it true or is it just something people want to see?

      A feel like its easily searchable- last year there was a 5.4 percent decline in international tourist arrivals to the us:

        That’s why I asked my question: I see a lot of ‘this group is down x%’, but I would really like to see it across the board. Maybe business travelers are way up? I don’t know :)

      Ironically, it’s one example where “people are saying” is actually true, both in the data and anecdotally. The US is a ‘toxic’ brand right now, especially to Canadians and Europeans ‘of conscience’ (which is understandable when our leader regularly threatens to our own allies.) Also, the exchange rate isn’t great for Japanese visitors and a few other countries, and the various trade wars (tariffs) have also impacted traffic as well. Feel free to attack me personally if you disagree. I enjoy insults. So fun.

      The challenge is having some sort of “control” or set of data points for a true comparison and be able to make a good hypothesis from that data. Its easy to blame Trump, but if you compare it to Canadian international traffic, that also is down.

      What I’d be curious to see is if there’s been a change in connecting traffic over the US versus using a different country and causing a “flyover” – example: If a European wants to go to Belize, they almost have to fly thru the US, however Copa flies from Panama; are we seeing any new interline traffic or connections to Belize outside of MIA/ATL, etc? Are we seeing Germans fly thru the Dominican Republic, for example, to get to their Caribbean hot spot versus hopping the A380 to Miami and connecting from there.

      Speaking of Copa, their traffic keeps going up and up, including record load factors to the US. Which then goes back to why is traffic down for other markets – is it access to flights, lower fares, etc. While we’re seeing Westjet pull back US flying, we see Air Canada *increasing* it. Is that strictly transborder flights, or are they getting more connecting flights to other places over Van, Toronto, and Montreal? Even Porter is expanding.

      Catch my point?

      1. Brett Avatar

        SegmentKing – There’s a lot that I disagree with here. For AC, US seats this summer are up 10% vs last year but that only brings it up to the same level as ’24. But you talk about needing a control, you have to compare it to other regions. The US is flat vs 2024, but Caribbean is up 28% and domestic is up 9% of a huge base. Relative to other geographies, the US lags. And Porter? Porter has no choice, because it needs to find a place to put all of those airplanes it over-ordered.

        You can try to spin it however you’d like, but the Trump Administration’s policies have unquestionably led to a massive drop. There’s a good chart here that shows it.

        As for people connecting through the US, that is tougher to isolate without doing some more data massaging. But people always used the US as a point of last resort anyway because there is no transit without visa. I imagine that was low and probably hasn’t changed all that much, but I don’t have that readily available.

    Jorg – That is far more than an aviation topic since people come to the country in a lot of different ways. But it is absolutely true, and you can see it just about anywhere. For example, here are numbers on vehicle traffic plunging between BC and Washington.

    Financial Times has some data: foreign visitors to the US fell 4.2% in 2025, while international travel worldwide rose 4%. Cites concerns over social policies but also impact of tariffs and tough exchange rates for Japanese tourists.

    I fly frequently to Mexico from ORD for work and occasionally have to visit San Diego (also for work). I tried CBX for the first time about three weeks ago and wow, what a great experience. Airfare from MEX to SAN was $500+ while my flight from MEX to TIJ was $101 (bought less than a week out). For an additional $60, I upgraded to First Class on Aeromexico. My only complaint about the experience was parking at a hard stand on arrival and having to be bussed to the terminal. But for the price, you can’t beat it.

    US Customs took less than a minute, including the X-raying of my baggage. Border Control was actually quite pleasant as well. They definitely seemed more chill than at other US ports of entry. Overall, highly recommend, even if just for the experience of “walking across the border.” Kind of surreal to do that for this Midwesterner.

    CBX (Cross Border Xpress) used to be a great deal right after it opened, when both the crossing fee and parking were much cheaper. Now it’s an expensive headache, and I generally avoid it.

    Yes, CBX is next to TIJ — but it’s far away from everywhere on the US side. You either have to pay for an expensive ride to/from the CBX terminal or pay very high parking rates. And unlike most airports, there aren’t really nearby “off-site” parking alternatives. Your options are the CBX lots, and one of those expensive lots is dirt. Depending on your situation, rides or parking can wipe out most (or all) of the savings you hoped to get by flying out of TIJ instead of SAN.

    If you do use CBX, I strongly recommend DO NOT BUY CBX TICKETS IN ADVANCE. Tickets are valid only for a specific date and typically can’t be changed or refunded. If your flight delay pushes you past midnight and you reach the CBX gate at 12:01 a.m. the next day, you must buy another ticket. Also, Aeromexico once sold me unredeemable CBX passes, and the refund process through my credit card was lengthy.

    My workaround has been to cross at San Ysidro instead: take a ride or the trolley to the border, cross on foot, then grab a taxi/Uber on the Mexico side for a quick ~$10 ride to TIJ. You can do the same in reverse — just pay attention to time of day. Unless you have Global Entry/SENTRI, the San Ysidro pedestrian line can be many hours long. In comparison, CBX lines have never appeared more than a hundred people deep.

    You definitely need more than 1.5 hours any peak season. The US <7 day line for Mexican passport control can easily be 15+ switchbacks.

    Do the Mexican immigration officers still slam the passport stamps? I swear they’re in competition to see who can stamp the loudest.

    I don’t think the comment above about date-specific tickets is accurate. I believe the date is used to determine what tier pricing you get. As long as the ticket you’re redeeming is the same or a higher tier than the date crossed, you should be good.

    Pro-tip – If a family has all their tickets on one phone, that person should go last. The number of times I’ve seen a family have all their tickets on the first person’s phone and have to throw it back over the gate is laughable.

    Hello, if I plan to purchase CBX tickets directly through CBX instead of airline, do you still enter TJX for departure or do you enter TIJ?
    I read that its TJX if you want to pay for CBX tickets along with airline tickets (which as you stated costs more).

    Also, I have been told that for those who do purchase CBX with airline, you can use your boarding pass as your CBX ticket?
    Any info. is appreciated.

    1. Erik Avatar

      I recommend buying when you arrive at CBX to avoid issues re validity of CBX ticket — see my comment above.

    2. Brett Avatar

      Linda – No, you would enter TIJ and not TJX if you buy CBX on your own. It’s just a regular domestic ticket at that point.

      I think that is true that you can use your boarding pass to scan as your CBX ticket, but since I didn’t buy it that way, I don’t know for sure.

    Thanks. I bought them last night and did not receive any email with QR code/tickets from CBX. I am waiting to hear back from them. I downloaded the app and I am now at least able to view the QR codes, but they do not have each person’s name attached. I am hoping once I am able to check in online, they will be linked to the boarding pass. That’s what the CBX website states.

    I will be buying them separately for my family’s tickets I need to purchase next.

    In the past when we missed our flight, we had to wait on the TJ side, so we did not have to get CBX tickets again. Still an inconvenience.

    Agree with the comments about expense. CBX is $50 round trip at the moment. I live North of San Diego in Carlsbad so difficult to access CBX via transit. My solution was to go train/trolley to San Ysidro; walk across and pay the taxi fixed rate of M$300 to the airport. Only downside: the walk is quite far to the taxi rank if you have baggage.
    I pay to come back across CBX for the convenience, and either Uber home or to the Iris Ave transit center where you can pick up the trolley.
    Regarding the FMM form. Make sure the printed receipt has the number of your FMM form. There are 2 receipts offered for the same transaction, so check this, then you should have no problem. At San Ysidro it took about 15 minutes to get through.
    It would be great if SD MTS would have a bus stop at CBX.

    Random question but is CBX even open right now given all thats going on?

    1. Brett Avatar

      Mike – I don’t know why it would close. There is no unrest anywhere even remotely near this area. Also, it’s a land crossing, and I don’t see why that would close at all.

  13. Colin Avatar
    Colin

    I don’t see any reason why it would close. The security situation will not reach it, unless it could be bombed from the road below, which seems unlikely. As the CBX website suggests: Check whether your flight is operating.
