Hey there, let’s talk about something that’s probably crossed your mind the next time you’re rushing through an airport, fumbling with a boarding pass or tapping a screen to check in: have you ever wondered if those self-service check-in terminals actually support more than just the language you speak? I know I did, back when I was first starting out in this game—way before I was deep in the weeds of building and maintaining these things for airlines across North America and Europe. Let me set the scene: it was 2018, I was at a tiny airport in Quebec, Canada, and I watched a group of French-speaking tourists stand around a touchscreen for 10 minutes, squinting at English text, because no one had bothered to make the terminal switch to their language. That’s when it clicked for me: check-in terminals aren’t just boxes that print boarding passes—they’re critical for making travel accessible, and if they don’t support multiple languages, they’re failing half the people trying to use them. Check-in Terminal
First off, let’s get one thing straight: no, not all check-in terminals support multiple languages, but the good ones (the ones that actually work for airlines and passengers) do, and it’s way more complicated than just “click a flag and it changes text.” When I say “good ones,” I’m talking about the ones my team designs, not the cheap off-the-shelf junk some discount suppliers peddle. Let’s break down why language support matters beyond just convenience. Think about it: international travel has exploded in the last decade. The UN World Tourism Organization says 1.5 billion people traveled internationally in 2019, and pre-pandemic numbers were already climbing 4% a year. A lot of those travelers aren’t native English speakers. If a terminal asks you for a passport number or a seat preference in English, and you don’t speak it, that’s not just a frustrating delay—it’s a security risk. What if you accidentally input the wrong passport number because you misread the text? That’s a huge headache for both the passenger and the airline. I’ve seen airlines lose thousands in rebooking fees because a passenger messed up a field due to a language barrier, so language support isn’t just a nice-to-have—it’s a compliance thing, too.
Now, let’s get into how these terminals actually handle multiple languages, because it’s not as simple as copying and pasting text into different files. Back when we were developing our latest line of terminals, we ran into so many headaches here. First, you have to decide what languages to support. It’s not just picking the most common ones—you have to look at the airline’s routes. If an airline flies from Tokyo to São Paulo, they’re gonna need Japanese, Portuguese, English, maybe Spanish? If you just add Spanish because it’s common, that’s useless for that specific route. Then there’s the actual tech behind it: we use what’s called a “language engine” that pulls text from a centralized database, not hard-coding every line. That way, if an airline updates a passenger agreement, we only have to change one entry in the database, not go through every single language file. But here’s the catch: some languages have characters that don’t work with standard fonts. Like, Arabic has right-to-left text, and if your terminal’s UI isn’t built to flip that, it looks like garbage—passengers can’t even read it. We had to test for that nonstop. We brought in bilingual testers for every language we add, not just our in-house engineers, because engineers often miss small stuff—like, in some languages, the word for “baggage” is longer, so the UI button has to stretch to fit without breaking. That’s the kind of detail that separates a terminal that works from one that’s a pain.
Wait, but what about the terminals that don’t support multiple languages? Why do some suppliers skip this? I’ve worked with a few cheap competitors, and their reasoning is basically “it adds cost, and most passengers speak English anyway.” That’s a garbage take, by the way. First, cost: sure, adding language support adds a little to the terminal’s price tag, but it saves airlines money in the long run. Less time spent helping passengers at the counter, fewer mistakes with booking or security. Second, “most passengers speak English”? No, that’s not true. Even in places where English is the second language, most travelers don’t speak it fluently. I saw a survey last year from the Airport Council International that found 60% of international passengers say language barriers are their biggest stress at airports, right after lost luggage. So why would suppliers skip this? Sometimes it’s laziness—they just use a pre-made terminal template that only has 2 or 3 languages. Sometimes it’s ignorance—they don’t do the research on what an airline’s actual routes need, so they just pick a handful of random languages. I once had a client come to us complaining that a competitor’s terminal had Icelandic, but no Danish, even though their hub was in Copenhagen. Total waste of space.
Let’s talk about real-world examples, because I don’t want this to just be tech jargon. Last year, we installed our terminals at an airport in Morocco, which serves a ton of French, Arabic, and English-speaking passengers. We tested every language before launch, and one thing we learned: passengers don’t just want the text translated—they want the terms to make sense in their local context. For example, in English, we say “checked baggage,” but in Moroccan Arabic, people say “sac à valise” (wait, no, that’s French—our tester told us the local term is something else entirely that doesn’t translate directly to English baggage). So we didn’t just use Google Translate for that—we worked with local travel agents to make sure the UI terms were what actual passengers would say, not a literal translation. That terminal now has a 92% success rate for self-check-ins, which is way higher than the airport’s old terminals (the ones that only had English and French, by the way). Another example: we had a client in Japan that flies a lot of routes to Southeast Asia, so they needed support for Japanese, English, Mandarin, Korean, and Thai. Their old terminals only had English and Japanese, so they had a 30% error rate on passport inputs from Thai passengers. After we installed our terminals with the full set, that error rate dropped to 2%. Those numbers don’t lie.
Wait, but what about when you’re at a small airport, or a regional terminal, not a big international hub? Do those support multiple languages? That’s another question I get a lot. Small airports often have tighter budgets, so they’ll buy cheaper terminals that have minimal language support. But even small airports can benefit from adding a couple of extra languages. For example, a regional airport in upstate New York that has a lot of Mexican travelers flying to Texas—they could add Spanish for like 50 bucks extra per terminal, and that would cut down on the time their ground staff spends helping passengers. I’ve had small airport clients tell me that adding just one extra language saved them 10 hours a week in counter time. It’s not just for big international hubs.
Now, let’s address a common misconception: some people think that if an airline has a mobile app with multiple languages, that’s enough, so the check-in terminal doesn’t need to. That’s such a bad call. Not everyone has their phone, or their phone battery dies, or they don’t want to download the app. I’ve seen so many passengers show up to the airport with a print-out of their boarding pass from home, but they need to check a bag or get a new seat, so they have to use the terminal. If that terminal only has the app’s default language, that’s useless. Also, some travelers, like older adults or people with limited tech skills, prefer using physical terminals, not their phones. So yeah, app language support doesn’t replace terminal language support—they work together.
I should also mention the regulatory side, because that’s a big one I didn’t think about early on. The International Civil Aviation Organization (ICAO) has rules about passenger-facing signage and tech at airports, and language support is part of that. A lot of countries require that critical travel information is available in at least two languages, often the local language plus English. So if a terminal doesn’t support the local language, the airport could get in trouble, or even get fined. We had a client in Germany that almost got a fine from the Federal Office for Civil Aviation because their old terminals only had English. They switched to our terminals with German, English, and French, and that was the end of that. So it’s not just about passenger comfort—it’s about following rules.
Now, let’s talk about what we do differently at our company (you know, the one that makes these terminals). We don’t just throw a bunch of languages at a terminal and call it a day. First, we sit down with the airline or airport, look at their route map, their passenger demographics, and figure out exactly which languages they need. Then, we work with native speakers of each language to translate and test every part of the UI—from the big buttons like “Print Boarding Pass” to the tiny text that says “Your flight is now boarding at Gate 12.” We also build in a one-click language switch, so passengers don’t have to dig through 5 menus to change it—just tap a flag or a “Change Language” button on the home screen. And we test for edge cases: like, what if a passenger is using the terminal in a language that uses different numbers? (Some countries use Arabic numerals, others use different scripts, so we make sure the terminal accepts both.) What about right-to-left languages like Hebrew or Urdu? We flip the entire UI automatically, so text flows the correct way. We even test in low-light conditions, because that’s when a lot of passengers use the terminal, and text in non-Latin scripts can be harder to read.
Wait, but is there a downside to having too many languages? Like, if a terminal has 20 languages, does that make the UI cluttered? Yeah, if you’re not careful. We’ve seen terminals that have a language menu so long you have to scroll for 2 minutes to find your language—total nightmare. So we limit the languages to the ones the airline actually needs, and we organize them by commonality. Like, English is always first, then the local language, then the most used international languages for their routes. That keeps the menu short and easy to use. We also add a search bar in the language menu, so if a passenger’s language isn’t in the top few, they can type it in instead of scrolling.
Let’s wrap this up with a real story that sticks with me. A few months ago, I was at a small airport in Mexico, checking in for a flight, and I saw an elderly couple—they didn’t speak much English, and the old terminal they were using only had Spanish and English. The wife was standing there, crying, because she couldn’t figure out how to select their seats. I went over to help, and I thought, “If this terminal had a third language, maybe for Zapotec or Mixtec, which are common languages in that area, they wouldn’t have struggled.” That’s when I realized language support isn’t just about major international languages like Spanish or Mandarin—it’s about the local, regional languages that passengers use every day. So that’s something we’re working on now—adding support for more indigenous languages, because too many airports and terminals ignore that.
At the end of the day, check-in terminals absolutely can support multiple languages, and every terminal manufacturer should prioritize that. It’s not a luxury—it’s part of making air travel accessible, safe, and stress-free for everyone. If you’re an airline or airport looking to upgrade your check-in terminals, don’t settle for a one-language terminal that’s gonna leave half your passengers frustrated. We build terminals that work for every traveler, no matter what language they speak. If you’re interested in learning more, reach out to us to chat through your needs—we’d love to help.
