These are the 20 best airlines in the world, according to one survey of travelers see the full list

Last year, Delta came in at 24 on Skytrax's prestigious list. This year, it's the only US carrier to make the top 20 ranks.

The second-best US-based carrier — United Airlines — came in at 49th.

The national carrier of New Zealand climbed from last year's 30th place into this year's top 20. Air New Zealand flies to Asia, the Americas, several Pacific Islands, and its neighbor Australia.

The national carrier of the UK operates domestic and international flights to Europe, Asia, Australia, the Americas, the Middle East, and Africa.

The Australian airline's ranking on this year's Skytrax's list is a disappointment from its 2022 rank of fifth place. At least it was voted the safest airline in the world this year.

The airline operates routes to New Zealand, Europe, the Americas, Asia, and South Africa.

The India-based airline flies various domestic and international routes in Europe, the Middle East, and Asia. Its ranking in this year's Skytrax list is an improvement from its 20th-place ranking in 2022.

Last year, the national carrier of the Republic of Fiji was ranked 36th in Skytrax's top 100 list. It currently flies to various Pacific Islands, Europe, Asia, North America, Australia, and New Zealand.

Spain's largest airline flies to almost 140 destinations in Europe, the Americas, Africa, the Middle East, and Asia. It's a big win for the country's national carrier. Like Air New Zealand and Fiji, Iberia didn't make Skytrax's top 20 list last year.

The national carrier of the United Arab Emirates operates routes in the Middle East, Asia, Australia, Africa, Europe, and North America.

The national airline of Switzerland, also known as SWISS, flies to the Americas, Europe, Africa, Asia, and Australia.

The Haikou, China-based airline, one of the country's largest, has a network of routes in Asia, Europe, and North America.

Rounding out the top 10 list, Korea's flag carrier flies routes in the US, Europe, Asia, Australia, and New Zealand. Its cargo branch Korea Air Cargo is also one of the largest in the world.

The Taiwanese carrier — which also won Skytrax's "world's best premium economy class" — operates routes to Australia, Asia, North America, and Europe.

The Hong Kong-based carrier operates routes throughout North America, Europe, the Middle East, and Asia-Pacific. The airline also took home Skytrax's "world's best inflight entertainment" title.

The national airline of France operates flights from Paris to cities across Asia, Africa, and the Americas.

The Istanbul-based airline currently serves almost 270 routes around Africa, the Americas, Europe, and Asia.

The Tokyo-based carrier squeaked into this year's top five best airlines list while also winning Skytrax' title for "world's best economy class." The airline flies routes in Latin and North America, Europe, and Asia-Pacific.

The Dubai-based national carrier of the United Arab Emirates operates a robust list of routes around the world in Africa, Asia, Europe, the Americas, and the Middle East.

Japan's All Nippon Airways (ANA) is the country's largest airline with over 130 domestic and international routes. The carrier also scored Skytrax's "world's cleanest airline" award.

For the first time since 2019, Qatar Airways has fallen from the top spot to second place. However, the Doha-based carrier still won additional awards with titles like "world's best business class."

Singapore's national carrier has been ranked the world's best airline after coming in second place in last year's Skytrax's survey. This year, Singapore Airlines also came on top for categories like "world's best first class."
