What Is The Cheapest Airline

I remember the first time I had to choose an airline for a family trip with my two toddlers. My mind was a whirlwind of priorities: price, comfort, safety, and, most importantly, how much legroom there was for my 2-year-old who insisted on crawling into the aisle seat. I scoured the internet for ‘what is the cheapest airline’ and was overwhelmed by the sheer volume of options, each touting different deals and promotions. It felt like a minefield of confusing information, and I wasn’t sure where to begin.

What I didn’t expect was how much of an impact the right airline could have on our travel experience. Not only did we save money, but we also found an airline that offered a level of service that made the journey easier for all of us. It was a revelation that cheap didn’t have to mean compromised, and I wanted to share that journey with other parents who are in the same boat.

If you’re looking for ‘what is the cheapest airline’ and want more than a list of options, read on. I’ve tested several airlines with my own kids. I’ll walk you through the real factors that matter most when choosing an airline on a budget, without sacrificing the comfort and safety of your little ones.

What Makes an Airline Cheap and Family-Friendly?

As of October 2026, the cheapest airlines are usually low-cost carriers, but they may not always be the best fit for families with young children. For example, budget airlines may offer the lowest prices but charge fees for carry-ons, seat selection, and even extra legroom. I found that while the base fare for a round-trip ticket from New York to Orlando was $250 on one budget airline, the total cost went up to $350 once I added the baggage fee and purchased a seat for my toddler.^[1]

Another factor to consider is the availability of child-friendly amenities. Some airlines offer bassinet rentals, seatbelt extenders, and even onboard strollers for free. I’ve had a hard time with airlines that charge for baby bassinets, which can add $50 or more to a trip.

It’s also important to check for hidden fees, such as those for checked luggage, priority boarding, or even changes to your itinerary. I once purchased a ticket with a budget airline thinking I’d save money, only to find out that changing the departure time would cost me nearly 50% of the ticket price.^[2]

Which Airlines Are Actually the Cheapest?

In the United States, airlines like Spirit, Frontier, and Allegiant Air are known for offering the lowest fares. However, they often have additional fees for things like checked bags, seat selection, and even extra legroom. On a recent trip to Florida with my two kids, I found that Spirit Airlines offered a base fare of $150 round-trip. The total cost jumped to $225 once I added two carry-ons and a bassinet rental.^[3]

International budget airlines, such as Ryanair in Europe or AirAsia in Asia, can also be great options. I once flew with AirAsia from Bangkok to Phuket for a family trip and paid just $100 for three tickets after using a promotion code. However, I had to pay an extra $20 for each piece of checked luggage.

It’s also worth comparing prices across different platforms. Sometimes booking through an airline’s website directly can save money compared to third-party sites. I’ve saved over $100 on a round-trip flight by booking directly with the airline instead of through a travel agency.

Cheap doesn’t mean uncomfortable—look for airlines that offer child-friendly amenities without extra fees.

How to Find the Best Deals on the Cheapest Airline

I’ve found that using price comparison websites like Google Flights, Skyscanner, or Kayak can help you find the cheapest airline deals. These tools allow you to filter by budget, number of stops, and even luggage allowance. On one occasion, I found a flight from Chicago to Las Vegas for just $90 per person by using a fare calendar on Google Flights.

Booking early is another key strategy. I’ve noticed that prices tend to be lower the earlier you book, especially for family trips. On a recent trip to San Diego, I booked three months in advance and paid $200 per person, whereas the same flight three weeks later was $300 per person.

You should also consider flying mid-week or on less popular days, as prices can be significantly lower. I’ve saved up to 40% on flight prices by flying on Wednesdays instead of Fridays. It’s a small change that can make a big difference in your travel budget.

What to Look for in a Cheap Airline for Families

Free amenities can make a big difference in the comfort of your family trip. I’ve found that some budget airlines offer free bassinets or seatbelt extenders for free, which can save you money and make the flight more comfortable for your toddler. On one flight, I was able to rent a bassinet for free from an airline that I would have otherwise paid $50 for.

It’s also important to check the airline’s cancellation policies. Some budget airlines offer flexible cancellation options, while others charge a hefty fee. I’ve had to cancel a trip with one airline and was charged $150 in fees, which was a big financial hit.

Another thing to consider is the availability of family seating. Some airlines allow you to book seats together for free or at a discount, which is essential for traveling with young children. I’ve had a bad experience with an airline where my toddler was seated separately from me, which made the flight stressful and uncomfortable.

The Hidden Costs of the Cheapest Airline

I’ve learned the hard way that the cheapest airline may come with hidden costs that can quickly eat into your budget. For example, some budget airlines charge for checked luggage, priority boarding, and even the use of a child’s seat. On a recent trip, I found that a budget airline charged $25 for each checked bag, which added up to $50 for a family of four.

Another hidden cost I’ve encountered is the fee for changing your flight date or time. Some airlines charge a fee of $100 or more for any changes to your itinerary, which can be a big expense if your plans change.

It’s also important to read the fine print regarding baggage allowances. Some airlines only allow one carry-on and one personal item, which can be a problem if you have a toddler who needs a stroller or a diaper bag. I’ve had to pay extra for an additional carry-on on several occasions.

How to Save More on the Cheapest Airline

Loyalty programs can be a great way to save on the cheapest airline. I’ve found that some airlines offer discounts or bonus miles for frequent flyers, which can help reduce the cost of future trips. I’ve used an airline’s loyalty program to get a 20% discount on a family flight to Orlando.

Signing up for email alerts is another smart move. Airlines often send out special promotions or discounts to their email subscribers. I’ve received several deals on flights for my family just by signing up for an airline’s email list.

Booking during off-peak times can also lead to significant savings. I’ve saved up to 50% on airfare by traveling during the off-season, such as in the middle of the week or during the school year.

Loyalty programs and email alerts can lead to big savings on your next family trip.

Choosing the Right Airline for Your Family’s Needs

When choosing the cheapest airline for your family, it’s important to consider your priorities. If you’re looking for the lowest price, a budget airline may be the way to go, but if comfort and convenience are more important, you may want to choose a premium airline.

I’ve found that some budget airlines offer better service than others. For example, one airline I flew with had friendly crew members and even offered free snacks to children, while another had a more impersonal service.

It’s also important to think about the type of trip you’re taking. If you’re traveling for a short weekend getaway, a budget airline may be the best option. If you’re traveling for an extended period, you may want to choose an airline with more amenities and services.
