As big a market as there is for luxury travel in business and first class in today’s day and age, low-cost airlines remain the go-to choice for tonnes of travellers around the world, especially for those who look to make the most of their money while continuing to explore the planet through backpacking trips, quick hops to neighbouring countries and the occasional transcontinental journeys.
Though travellers are looking to secure cheap tickets, safety, cleanliness, connectivity and on-time performance are some of the most vital attributes that they look for when making the choice – all of which are some factors which Skytrax has considered in its 10 best low-cost airlines in the world ranking for 2025, which is led by Air Asia for the 16th straight year and includes a number of usual suspects.
Here is a look at those who make the coveted list:
Best Low-Cost Airlines in 2025

1. AirAsia (AK)
AirAsia (AK) has taken home the accolade for being the best low-cost airline in the world for a 16th straight year. The airline is targeting 70 million customers this year and has made an auspicious start in its bid to make the most of the summer and end-of-year travel boom.
With subsidiaries in Cambodia, Indonesia, the Philippines, and Thailand, Air Asia is one of the world’s largest low-cost carriers.
In addition to providing cheap tickets, they also service some of the globe’s most visited countries, offer exceptional connectivity in the region, all while providing a welcoming experience aboard that is familiar with Asian hospitality.

2. Scoot (TR)
Scoot (TR) is the best long-haul low-cost airline in Skytrax’s list. Owned by Singapore Airlines, it comes as no surprise that the carrier ranks very highly. They mix a low-cost brand with SQ’s standard of making passengers feel at home 35,000 feet above the ground.
While it connects Singapore with a majority of Asia as well as cities in Australia and Europe, what really stands out about Scoot is its Changi hub, which is far from a low-cost travel experience.
By flying on Scoot, passengers can pass through an efficient hub, get served value-for-money food catered by Singapore Airlines (SQ), and those with better budgets can also avail the airline’s recliner business class seats on the Boeing 787s at lower costs than full-service competitors.

3. IndiGo Airlines (6E)
India’s largest airline and one of the world’s fastest-growing carriers, IndiGo, ranks third. 6E operates over 2,000 flights every day and provides seamless domestic connectivity to Indian travellers alongside an expansive international network in Asia and, most recently, to Europe too.
IndiGo has fairly comfortable seats in economy class, and their new Stretch product offers a decent business class option too.
Their best attribute, however, is an exceptional network in India, on-time performance, and food, which is priced very nominally and provides great value financially as well as from a taste perspective.
As they venture into the long-haul space, it will be interesting to see whether 6E can pip Scoot next year.

4. Eurowings (EW)
Eurowings, owned by the Lufthansa Group, takes fourth place in the Skytrax rankings in this category. They provide low-cost connectivity to travellers primarily in Austria, the Czech Republic, and Germany by connecting them to over 150 destinations.
The airline is a popular choice among travellers, not just those looking to cut costs but also those living in smaller cities whose airports are not best served by full-service airlines.
Thanks to its on-time performance, much of which is aided by a modern fleet and quick turnarounds, Eurowings is the largest low-cost carrier in the German market, offering good value for money over full-service counterpart Lufthansa.

5. Vueling Airlines (VY)
Vueling (VY) is based out of Barcelona and is the largest airline in Spain by fleet size and number of destinations.
Precisely, it flies to 120 destinations with a fleet of Airbus A320 family aircraft. It is a part of the International Airlines Group, which also runs British Airways and Iberia, amongst others.
Vueling operates as a leisure low-cost carrier, appealing to travellers who are backpacking or making the most of a thin budget.
They have hubs in some of Europe’s biggest tourist hotspots like Amsterdam, Barcelona, London, Paris, and Rome, offering a no-frills, seat-only fare that attracts over 30 million flyers every year.
Their fares are lower than inter-city train rides on average, while on-time performances make them a very attractive option.

6. Volotea
Volotea is the second Spanish low-cost carrier in succession to make the top 10 best low-cost airlines in the world list by Skytrax for 2025.
They are also headquartered out of Barcelona and, like Vueling, operate an Airbus A320 family fleet to close to 75 destinations.
What makes them an attractive option is their connectivity between smaller and mid-sized cities in Europe, which are underserved by full-service carriers.
They are also incentivised by secondary airports and tourism boards, so with lower operational costs, they can offer travellers a no-frills experience in the sky and remain a leading airline at a very cheap price without much competition from those that primarily look for a larger scale in bigger airports and cities.

7. Transavia France
Transavia France is a low-cost airline run by the Air France-KLM Group, offering point-to-point leisure connectivity between airports in France and the Netherlands.
In addition to keeping low fares between destinations, Transavia’s auxiliary products like seat selection, meals on board, and luggage costs are also very reasonably priced, therefore making them a popular choice among travellers who are transiting through full-service carriers as well.
Most of their flights are also sold in bundled tickets with Air France and KLM, leading to higher load factors, especially during holiday periods.

8. Iberia Express (I2)
Iberia Express is the low-cost subsidiary run by Spanish flag-carrier Iberia. The airline was founded in 2011 and is the third carrier from the country to make the coveted list by Skytrax, particularly due to its close linkage with its full-service parent counterpart.
Iberia Express works in tandem with Iberia to connect Madrid with cities in Spain, the Balearic Islands, and other European destinations.
With cheaper flights on the shorter sector, Iberia leverages Iberia Express to offer connectivity to passengers via its Madrid hub for long-haul sectors.
While a low-cost airline, unlike its parent company, its an on-time record and streamlined operation and experience with Iberia gives a generally strong impression.

9. Flynas (XY)
Flynas (XY) is the only carrier from the Gulf region to make the top 10 of the world’s best low-cost carriers list by Skytrax. Based in Saudi Arabia, the airline operates to nearly 70 destinations within the Middle East, the rest of Asia, Africa, and Europe.
Flynas leverages its solid geographic location to provide a budget option for travellers looking to fly within close proximity of Saudi Arabia. It is an especially popular option among blue-collar workers in the Middle East who cannot quite afford the luxury of travelling on full-service airlines.
Its hub in Medina means Flynas is also the best-connected airline for Islamic travellers undertaking pilgrimage trips to the city and consequently, a favourable choice.

10. EasyJet (U2)
easyJet (U2) rounds off the list by bagging the 10th spot. It is a British carrier with several operating hubs in the country, along with a large number of bases in mainland Europe through its subsidiary, EasyJet Europe.
EasyJet is a popular option because of its connectivity between over 180 destinations in Europe and some parts of Africa. Besides an on-time performance, they offer some of the cheapest available tickets and a safe flying experience, with only one incident in three decades since being founded.
Their subscription-based program offers travellers free or discounted auxiliaries, making them very popular. Additionally, their efforts to make flying sustainable serve as a social responsibility factor.

Bottom line
The big takeaway is that while low-cost flying remains popular among those connecting on short-haul routes, it is slowly starting to be impactful on the longer sectors as well. Scoot’s claim to the second spot is a strong indicator of the importance of efficiency and branding.
It will be interesting to see how IndiGo performs going forward, now that it has started flights to Europe.
Meanwhile, carriers like Jetstar and Ryanair not making the cut show that in spite of looking to cut corners, travellers are unwilling to compromise on their overall travel experience by accounting for factors like ground service, on-time performance, safety record, and no-frills ticketing options.
