I used to think cheap flights were too good to be true. Hidden fees, terrible seats, delays — the whole budget airline horror story. Then I actually started booking them regularly, and I realized the trick isn’t which airline you pick, it’s knowing how each one works before you hit “buy.”
So if you’re trying to travel more without draining your bank account, you’re in the right place. Below you’ll find the 10 cheapest flight companies operating right now, who they’re best for, and what to watch out for with each one.
10 Cheapest Flight Companies You Should Know
1. Ryanair
Best for: Budget travel across Europe
Ryanair continues to lead Europe in low-cost travel. Its base fares are among the lowest in the market, and travelers who plan carefully and manage optional extras like baggage or seat selection can save significant amounts.
The key with Ryanair is simple: travel light. If you can fit everything into a small carry-on that goes under the seat, your base fare stays rock-bottom. The moment you add a checked bag or seat selection, the price climbs fast.
- Operates: Europe-wide, some North Africa routes
- Known for: Extremely low base fares, massive network
- Watch out for: Strict bag size limits, secondary airports far from city centers
2. easyJet
Best for: Short and medium-haul European flights
easyJet is a popular choice for budget travelers across Europe. Frequent promotions and straightforward booking options make it easy to secure affordable tickets without a lot of hassle.
Unlike Ryanair, easyJet tends to fly into main airports rather than remote secondary ones — which is a real advantage. Prices are slightly higher, but the convenience usually makes it worth the small difference.
- Operates: Europe, North Africa, Middle East
- Known for: Good coverage, main airport access
- Watch out for: Bag fees that add up quickly if you’re not careful
3. AirAsia
Best for: Affordable travel across Southeast Asia
AirAsia is one of the most recognized budget carriers in the world. It regularly offers regional flights across Asia for under $50 USD, making it a go-to option for anyone exploring Southeast Asia on a tight budget.
The airline launched with the tagline “Now Everyone Can Fly,” and it has largely delivered on that promise. Its network spans dozens of countries across Asia, and it operates a modern, reliable fleet.
- Operates: Southeast Asia, India, Australia, Japan
- Known for: Ultra-low fares, wide Asian route network
- Watch out for: Add-ons like meals and bags are priced separately
4. Spirit Airlines
Best for: Cheap domestic flights in the United States
Spirit is the king of bare-bones fares in the US. Base prices are genuinely low — you can find flights for $40 or less on popular routes. The trade-off is that almost everything else costs extra: carry-on bags, seat selection, even printing your boarding pass at the airport.
Spirit has faced financial difficulties in recent years, so it’s worth purchasing travel insurance when booking. That said, for short domestic hops where you’re traveling light, it’s hard to beat the price.
- Operates: US domestic, Caribbean, Latin America
- Known for: Some of the lowest base fares in the US
- Watch out for: Very strict personal item size rules, limited legroom
5. Frontier Airlines
Best for: Budget US domestic travel with a newer fleet
Frontier operates an all-Airbus A320 family fleet and has built a reputation for aggressive fare sales. Base fares on routes like Denver to Las Vegas can start as low as $29. Like Spirit, it follows an à la carte pricing model — you pay only for what you actually need.
Frontier has been rolling out new features including first-class seating options and elite loyalty perks, which gives it a slight edge over Spirit in the comfort department.
- Operates: US domestic, Mexico, Caribbean, Central America
- Known for: Young fleet, aggressive sale fares
- Watch out for: On-time performance is inconsistent
6. Wizz Air
Best for: Ultra-cheap flights in Central and Eastern Europe
Wizz Air is the budget airline of choice for travelers across Central and Eastern Europe. It serves many destinations that larger carriers ignore, connecting cities like Budapest, Warsaw, Bucharest, and Sofia with destinations across Europe and beyond.
Fares are genuinely competitive, and the airline has been expanding aggressively into the Middle East and Central Asia. Its Wizz Discount Club membership can unlock additional savings if you fly frequently.
- Operates: Central/Eastern Europe, Middle East, UK
- Known for: Extremely low fares in underserved markets
- Watch out for: Bag allowance is very limited on basic fares
7. IndiGo
Best for: Cheap flights within India
IndiGo is India’s largest airline by market share, holding over 58% of the domestic market. It operates more than 350 aircraft and has placed massive orders to support continued expansion. For anyone traveling within India, IndiGo is almost always the cheapest option.
Fares are kept low through high efficiency and a single aircraft type operation. The airline is reliable for domestic travel, with a wide network covering virtually every major Indian city.
- Operates: India domestic, select international routes
- Known for: Dominant market share, low domestic fares
- Watch out for: Basic service, extra fees for luggage
8. Pegasus Airlines
Best for: Budget travel connecting Turkey with Europe and the Middle East
Pegasus Airlines connects Turkey with Europe, the Middle East, and Central Asia at very competitive prices. For anyone flying in or out of Turkey, Pegasus is almost always worth checking before booking a full-service carrier.
The airline operates from Istanbul Sabiha Gökçen Airport and offers a solid network at prices significantly below Turkish Airlines on most routes. Booking early typically gets you the best deals.
- Operates: Turkey, Europe, Middle East, Central Asia
- Known for: Low prices on Turkish routes, wide network
- Watch out for: Sabiha Gökçen Airport is on the Asian side of Istanbul
9. Jetstar
Best for: Budget long-haul travel in the Asia-Pacific
Jetstar, a subsidiary of Qantas, was ranked the world’s best budget long-haul airline in the 2026 Airline Ratings. It operates Boeing 787 Dreamliners on longer routes, offering genuinely affordable fares on Australia–Asia corridors while still giving you optional add-ons like meals, baggage, and in-flight entertainment.
If you need to cover serious distance on a budget — say, Sydney to Bali or Melbourne to Tokyo — Jetstar is one of the few budget carriers that makes long-haul travel affordable without feeling completely miserable.
- Operates: Australia, Asia-Pacific, Japan, Vietnam
- Known for: Affordable long-haul routes, optional comfort upgrades
- Watch out for: Fees for bags and seat selection on base fares
10. Volaris
Best for: Budget travel in Mexico and Latin America
Volaris is Mexico’s largest ultra-low-cost carrier, operating more than 100 aircraft across Mexico, the US, and Central America. For travelers heading to or from Mexico, it consistently offers some of the lowest fares available.
Like the other ULCCs on this list, Volaris keeps base fares very low and charges separately for everything else. Book early, skip the checked bag if you can, and you’ll find the prices hard to argue with.
- Operates: Mexico, US, Central America
- Known for: Low fares across Mexican routes
- Watch out for: À la carte pricing for all extras
Tips to Get the Cheapest Fares on Budget Airlines
You’ve picked your airline — now here’s how to actually keep the cost down:
- Book early. Budget airlines release their cheapest seats months in advance. The closer you get to the departure date, the higher the price goes.
- Travel light. The biggest hidden cost with budget carriers is baggage. A small personal item that fits under the seat is almost always free.
- Be flexible with dates. Flying mid-week (Tuesday or Wednesday) is almost always cheaper than weekends.
- Check secondary airports. Budget airlines often use smaller airports. Make sure you factor in the cost of getting to/from those airports before you celebrate the cheap fare.
- Skip seat selection. Unless you really need a specific seat, skip it. Let the airline assign one for free at check-in.
- Use the airline’s app. Many budget carriers charge a fee for airport check-in. Always check in online or via the app.
