One of the easiest ways to save money when you travel is to opt for cheaper flights. But just because you’re saving money on air travel it doesn’t mean you’re stuck with a low-quality flight. We’ve put together a list of airlines you should make sure to keep in mind if you’re looking to save money on airfare. These are the budget airlines every traveler should know.

EasyJet

Headquartered in London at the Luton Airport, EasyJet has focused on offering low-cost air travel since its inception in 1995. Combined with EasyJet Europe and EasyJet Switzerland, the company operates more than 200 planes and is growing more popular every year. Since 2017, EasyJet has even offered long-haul flights by partnering with other airlines like Norwegian and WestJet.

Jetstar

Jetstar is a subsidiary of Australian airline Qantas, was formed in 2003 and is based in Melbourne. The airline carries 8.5 percent of all passengers traveling in and out of Australia and is definitely worth looking into if part of your journey is taking you into or through that country. The airline connects Australia to a variety of destinations including China, Japan, New Zealand, Singapore, Thailand, Vietnam and even the United States, with a destination in Honolulu.

Southwest

If you’ve flown within the United States, chances are you’re familiar with Southwest. That’s likely true no matter where you fly, as it’s the world’s largest low-cost air carrier. Not only does Southwest feature low-cost flights, but the airline offers customers free checked bags, with two bags free even in economy seating.

With a fleet of more than 700 Boeing 737s, Southwest offers a large variety of destinations and is planning to bring service to four destinations in Hawaii in 2019. Southwest has long been known for offering above-average service for the money, and that doesn’t seem like it will change any time soon.

Eurowings

Eurowings is a subsidiary of German airline Lufthansa and is headquartered in Düsseldorf. It hasn’t always been a low-cost carrier; Eurowings started as a regional airline before switching to offering low-cost flights in 2014. The airline flies to Bangkok, Cancun, Havana, New York and Las Vegas among others.

Its cheap flights aren’t the only thing Eurowings has to offer, either. The airline is known for its cheap in-flight food and beverages. If you’re looking to tie one on or get a quick bite to eat during the next leg of your journey, that’s something worth keeping in mind.

Norwegian

Like Eurowings, Norwegian hasn’t always been known for its low-cost flights. The Oslo-based airline launched in 1993 but only began offering low-cost flights in 2002. The airline has several fully owned subsidiaries, including Norwegian Long Haul, Norwegian Air International and Norwegian Air UK.

Since 2013, Norwegian has put more focus on adding long-haul flights. The airline offers service to a number of destinations, including Buenos Aires, Singapore, Austin, Chicago, Orlando, Miami, New York, Los Angeles and Seattle.

JetBlue

With headquarters in New York City, JetBlue is the sixth largest airline in the United States. The airline offers flights to more than 100 destinations in the U.S., Mexico, Central America, South America and the Caribbean. Launched in 1999 as NewAir, JetBlue has been a low-cost carrier for as long as it has existed.

Despite the low cost, JetBlue offers free in-flight entertainment as well as snacks and drinks. The airline also boasts more legroom than its competitors, which could be a major boon considering the ever-shrinking size of airline seats.

AirAsia/AirAsia X

AirAsia was founded in 1993, and the Kuala Lumpur-based airline has been offering low-cost flights ever since. AirAsia Group, which includes several fully owned subsidiaries, offers flights to more than 165 destinations across 25 countries. For the past 10 years, AirAsia has consistently won awards for being the world’s best low-cost carrier.

One of those subsidiaries, AirAsia X, focuses exclusively on long-haul flights, with destinations in Auckland, Sydney, Jaipur, Hawaii and others. This airline has the notable distinction of currently being the cheapest airline in the world, in terms of cost per mile. If you’re looking to save a buck while traveling, that’s good to keep in mind.
