World's Cleanest Airlines: Who Actually Won, and Who's About to Find Out

I have strong feelings about cleanliness on an airplane, feelings that border on the moral. A dirty tray table is not a small thing to me. It is a preview of the whole flight, a little clue the airline leaves you about how much they actually care whether you have a decent day. So when I went looking for who does this best, I expected a tidy little list. What I found instead was a mess, and not the kind you can wipe down with a sanitizing wipe.

What Actually Makes an Airline "Clean," According to the People Who Rate This

Before we get to who's winning, it's worth knowing who's judging. The most respected cleanliness ranking in aviation comes from Skytrax, the London-based outfit that surveys tens of millions of travelers a year and hands out what everyone in the industry calls the Oscars of aviation. Their cleanliness category looks specifically at the presentation of seat areas, tray tables, carpets, cabin panels, and washrooms, based on real passenger ratings collected over several months of flying. It is, as these things go, about as rigorous as airline rankings get.

Who's Actually Cleanest Right Now

Here is where I have to gently correct the record, because the last version of this list had some trouble. It named ANA the cleanest airline in the world, then, a few entries later, named ANA again, as though the airline were so clean it deserved to win twice. It also left out the actual reigning champion entirely.

According to Skytrax's most recent completed rankings, the world's cleanest airline is EVA Air, the Taiwanese carrier, which jumped from third place the year before straight to the top spot, on the strength of cabins that reviewers described as spotless from carpet to ceiling, including the bathrooms, which is the detail that always separates the truly clean from the merely tidy. Behind EVA Air, in order, came:

1. EVA Air (Taiwan) – the reigning champion, and also holder of a five-star Skytrax rating for ten consecutive years running.
2. ANA All Nippon Airways (Japan) – runner-up, and still the airline people mean when they say a plane feels brand-new even after thousands of flights.
3. Cathay Pacific (Hong Kong) – third place, with a reputation for keeping galleys as odor-free as the cabin itself.
4. Qatar Airways (Qatar) – fourth overall, and also the reigning World's Best Airline, which tells you cleanliness and luxury aren't mutually exclusive.
5. Singapore Airlines (Singapore) – fifth, still blending five-star service with cabin materials designed to be easy to sanitize.
6. Hainan Airlines (China) – sixth, known for attention to hidden surfaces like air vents and seat crevices that other airlines skip.
7. STARLUX Airlines (Taiwan) – seventh, a newer entrant that's climbed fast on the strength of its cabin presentation.
8. Japan Airlines (Japan) – eighth, where even short domestic hops under an hour get the same meticulous treatment as long-haul flights.
9. Korean Air (South Korea) – ninth, with spotless cabins and investment in cabin air purification.
10. China Southern (China) – rounding out the top ten.

Notice what's missing: not a single US carrier cracked the global top twenty. That's not a knock on American hygiene standards so much as a reflection of who tends to win these surveys generally, since Asian carriers have dominated cabin-presentation categories for years. If you're flying domestically and want the cleanest option available to you, Delta has held the title of cleanest airline in North America, which is worth knowing if your trip doesn't involve crossing an ocean.

A Ranking That's About to Change

Here's the thing about writing any version of this list right now: it has an expiration date stamped on it already. Skytrax holds its awards ceremony annually, and the next one lands at the Langham Hotel in London on September 18, 2026, just days from whenever you're reading this. Whatever gets crowned there will bump this exact list, the same way EVA Air bumped whoever held the title the year before. If cleanliness is genuinely the deciding factor in how you book a flight, it's worth checking the freshest results before you commit, rather than trusting a list, including this one, that was accurate the week it was written.

What Separates a Genuinely Clean Airline From One That Just Says So

The airlines that consistently place well here tend to share a few habits, and none of them are complicated. They disinfect high-touch surfaces, seatbelt buckles, tray tables, entertainment screens, between every single flight, not just once a day. They run HEPA air filtration that cycles the entire cabin's air every few minutes, which matters more on a nine-hour flight than most people realize. They check lavatories multiple times mid-flight instead of just before landing. They hand out bedding and amenities in sealed packaging instead of a stack that's been sitting in a bin. And their cabin crews visibly clean throughout the journey, not just during turnaround, which is the difference between an airline that cares and one that's just performing for the pre-boarding photo.

How to Fly Cleaner Yourself, Regardless of Who You Book

You can't control which airline operates your route, and sometimes the cleanest carrier in the world simply doesn't fly where you're going. What you can control is smaller but still useful. Bring your own sanitizing wipes and give your tray table, armrests, and seatbelt buckle a once-over before you settle in, since those are the surfaces that get the least attention between flights regardless of airline. Skip the seatback pocket for anything you actually plan to eat or touch again, since it's rarely cleaned as thoroughly as the tray table. And if hygiene genuinely factors into how you book, check an airline's published cleaning protocols before you fly, since the better carriers are often happy to tell you exactly what they do and when.

The Bottom Line

The cleanest airline in the world, as of the most recent completed rankings, is EVA Air, not the airline the old version of this list gave credit to, twice, while somehow forgetting the actual winner. That's worth knowing. What's more worth knowing is that this whole list resets again this month, so treat any "cleanest airline" ranking, including this one, the way you'd treat a expiration date: good for now, not good forever.
