This ranking is based on a thorough evaluation of key aviation safety factors, including each airline’s fatality and serious incident record, fleet age and maintenance standards, international safety audits and certifications, as well as pilot training and overall safety culture. Importantly, being a low-cost airline does not mean lower safety standards. Many budget carriers operate modern aircraft and follow strict safety regulations that are comparable to those of full-service airlines.

Tips for Choosing a Low-Cost Airline
• Compare fares and extra fees
Low base fares often don’t include baggage, seat selection, meals, or even airport check-in. Always calculate the total cost before buying.
• Check the airline’s route network
Some budget airlines focus only on short regional routes, while others operate long-haul flights. Make sure the airline actually fits your travel plan.
• Look at aircraft age and fleet type
Airlines with newer aircraft usually offer better fuel efficiency, quieter cabins, and a more comfortable flight experience.
• Review baggage policies carefully
Cabin baggage size limits can be strict. Some airlines charge even for standard carry-on bags, so check dimensions and weight rules in advance.
• Consider airport choices
Many low-cost airlines use secondary airports that may be far from the city center. Avoid cheaper flight but higher transport cost.
• Check punctuality and reliability
A cheap ticket isn’t worth it if the airline frequently delays or cancels flights. Look for airlines known for on-time performance.
• Understand seat and comfort options
Some airlines offer paid upgrades like extra legroom, priority boarding, or quiet zones. These can make a big difference on longer flights.
• Review change and cancellation policies
Low-cost tickets are often non-refundable. If your plans might change, see whether flexible add-ons are available.
• Look at onboard services
Meals, entertainment, and Wi-Fi are usually not included. Decide if you’re okay bringing your own snacks or entertainment for the flight.
• Join membership or discount programs
Frequent travelers can save more through airline membership clubs or promo alerts that give access to exclusive fares.
What You’ll Get in the Cabin on a Low-Cost Airline
• A standard seat
Your ticket includes a regular economy seat. Legroom may be slightly tighter than full-service airlines, but it’s comfortable enough for short and medium flights.
• One small personal item
Most low-cost airlines allow a small bag (like a backpack or handbag) that fits under the seat in front of you, free of charge.
• Safe and modern aircraft
Despite the low price, these airlines operate well-maintained aircraft that meet international safety standards.
• Buy-on-board food and drinks
Meals are usually not included, but you can purchase snacks, drinks, and sometimes hot meals during the flight.
• Cabin crew assistance
Friendly cabin crew are always available for safety briefings, service, and passenger assistance just like on any other airline.
• Paid seat selection (optional)
If you don’t pay to choose your seat, it will be assigned automatically at check-in. You can upgrade for extra legroom or preferred seats.
• Overhead cabin baggage (sometimes paid)
Some airlines include a cabin suitcase, while others charge extra. Always check baggage rules before your flight.
• Wi-Fi (usually paid add-on)
Some low-cost airlines now offer onboard Wi-Fi for an extra fee. Speeds and coverage may vary, and it’s often best for messaging rather than heavy streaming. While onboard Wi-Fi can help during the flight, you’ll still need mobile data once you land, and international roaming can be very expensive.
That’s why a lot of travelers use Eskimo eSIM. Just install it before your trip and you’re connected the moment your plane touches down. They’re even offering a free trial with 500MB of global data you can use in 109 countries, which is perfect for getting online right away.
• Paid entertainment or none at all
Many low-cost airlines do not provide seat-back screens. Bringing your own device with downloaded movies or shows is a smart idea.
• Clean and simple cabin interiors
Low-cost carriers focus on efficiency, so cabins are usually modern but simple, without luxury extras.
• Optional add-ons for comfort
Extras like priority boarding, extra baggage, meals, and travel insurance can be added during booking.
