Budget Airlines: Snag Cheap Tickets But Watch Out for Hidden Fees

Travelers who are excited about taking those long-awaited trips aren’t nearly as cheery about the rising cost of airfare. This impacts budget airlines, too, but there are still many bargains to be had.  

For example, at one point this year Avelo Airlines offered flight from Atlanta to New Haven, Connecticut, for only $66 each way, with flights to Boston in October coming in even cheaper at $91 round trip. We found similar deals from Vegas to San Francisco for only $123 round trip. Plus, Avelo Airlines occasionally holds “flash sales” where you can take an additional 15% off your ticket prices. 

You can often find flights for under $100 with Frontier Airlines to popular locations like Las Vegas and Orlando. If you shop during promotional periods, like Amazon Prime Days and Black Friday, you can score huge discounts on base fare prices.  

Breeze Airways had flights between Tampa, Florida, and Charleston, South Carolina, for $39.

“Budget airlines are one of my favorite ways to find cheap travel. I have been able to get really great deals. That’s how I got my $99 flight to Iceland,” said Jen Ruiz, author and blogger for Jen on aJetPlane.com. “People want to spend more money on the destination than how they get there.”

Budget airlines offer cheap flights, for sure. But you need to be aware of additional fees and other costs that come with flying in and out of the secondary airports they serve.

“Things like checking your bags, buying your seat, getting your boarding pass — that shoots up the price,” said Scott Keyes, founder of Going, which hunts airline deals for more than 2 million free and paid subscribers. 

Flying on low-cost carriers “can be a very good deal for someone traveling light and if you don’t care what seat you have,” he said.

10 Budget Airlines

Check these 10 budget airlines for lower-priced airfare. Yes, Southwest is a major carrier because it flies to many destinations and doesn’t charge for luggage, but it is considered a budget airline because it offers fewer perks, such as first class and meal options.

Defining Budget Airlines

The difference between budget airlines and legacy carriers like American Airlines has become harder to define in the past 15 years, Keyes said. Since around 2015, legacy airlines have been offering more and more discounted airline tickets. Some also are charging for preferable seats or checked bags in order to compete with the low-cost airlines.

Here are three key differences between budget airlines and legacy carriers:

1. Fees

While discount airlines consistently offer lower fares, they may charge for selecting a seat, extra legroom, food, checked bags, carry-on bags and printing boarding passes on your departure date. Legacy airlines include some of those services in the price of the airfare.

2. Airports

Low-cost carriers tend to fly in and out of smaller, less busy airports where they pay less money for using the gates and save on other airport fees. For example, a low-cost airline is more likely to use the Hollywood Burbank Airport instead of Los Angeles International Airport in California, or Concord-Padgett Regional Airport, which is 17 miles from Charlotte Douglas International Airport in North Carolina.

3. Planes

Most discount airlines fly the same size jets used by legacy airlines. In fact, when the COVID-19 pandemic dramatically slashed flights, some traditional airlines sold their planes to discount airlines. But low-cost airlines do fly smaller planes than major airlines. Their planes are safe, though, according to Keyes.

“Flying has gotten remarkably safe. It’s not something I’m personally concerned about with budget airlines,” he said. “I would say the budget airlines’ planes might be a bit older, maybe a little bit dingier and just a little bit more cramped.”

For a short flight, the smaller space is bearable, Keyes said, but it’s more uncomfortable on a long-haul flight.

Again, these distinctions are not hard rules. There are exceptions. Southwest Airlines is considered a discount airline and serves many major airports. It also allows passengers to check two bags for free and there is no charge for carry-on bags.

The Hidden Costs of Budget Airlines

Flying on a budget airline often means a higher cost of ground transportation to and from the airport, if it’s not actually in or just outside the city where you are staying. And if you do have to change the flight, budget airlines tend to charge higher change fees than legacy carriers. And they may not fly to your desired destination every day. 

All airlines have flight cancellations because of weather and low sales, but major airlines usually have more options for getting passengers on alternate flights.

Canceled Flights Burn Time and Money

Low-cost airlines have fewer planes and fly fewer routes compared to major commercial airlines. So when a flight is canceled for weather, mechanical or scheduling reasons, it’s less likely you can be booked on the next flight in an hour or two.

Some budget airlines only fly specific routes on certain days of the week. So, if your flight home from your vacation is canceled, the airline may not have another one for four days. This disruption can add hundreds or thousands of dollars to your trip if it means more days in hotel rooms and extending rental cars. And, if you absolutely have to get home and book a flight on another airline on short notice, that can cost hundreds as well.

Legacy airlines offer more options. Many have also begun offering Basic Economy tickets, with prices comparable to budget airlines, but with their own set of limitations.

“A cancellation isn’t nearly as likely to upend your trip. (Major airlines) have partners…. and agreements. If your trip gets disrupted they can put you on another airline,” Keyes said. “I might be less inclined to book a (discount airline) flight to Chicago in February when weather constantly disrupts flights. But I might be more likely to get on a (discount airline) flight to Las Vegas or Hawaii in June.”

Additional Fees Add Up

Here’s a look at the add-on fees for a $147 round-trip Allegiant Airlines flight from Boston to Sarasota, Florida. At this rate, you get one personal item, everything else you might want costs extra. Checked bags get more expensive closer to the departure date. If you pay for a checked bag at booking, it’s $36, but if you wait until the airport, you’ll be out $75. Even carry-on bags carry a cost. Each carry-on is an additional $49 at booking and $75 at the airport. 

The costs continue to add up from there. Seat selection and trip flexibility/free cancellations add more to your final cost as well. If you choose to bundle these extras to your ticket at the time of booking, you’re looking at an additional $149.50 per person.

Spirit is one of the most recent discount airlines to get rid of cancellation fees. If you cancel your reservation within 24 hours of booking and the flight is still seven or more days away, you can get a full refund. In most other cases, you’ll receive a flight credit for the value of the flight fare.

Allegiant adopted a similar policy. If you cancel online or notify them within 24 hours of booking your trip, you can get a full refund. If you cancel outside that window without purchasing Trip Flex protection, you’ll be charged $25 per passenger and only receive a refund for the fare minus cancellation, carrier charges and booking fees.  

And JetBlue doesn’t charge a fee if changes are made online, but calling the airline to modify or cancel a flight costs you $25. It charges $100 for cancellations on its least expensive fares, called Blue Basic.

Getting To and From Remote Airports for those Cheap Flights

If you aren’t relying on friends or rental cars, the cost of an Uber or a Lyft from a remote airport to where you are staying can cut into your savings from the airline tickets.

In Arizona, for example, Phoenix-Mesa Gateway Airport, which more discount airlines serve, is 32 miles from the main Phoenix Sky Harbor International Airport. An Uber from Phoenix-Mesa to downtown Phoenix will cost around $50, while a ride from Sky Harbor is about $7. Consider the $43 difference each way plus any surge pricing if you are taking Uber during a busy time of day.

One perk of remote airports, however, is parking costs less. They are also less crowded, so cheap flights can save time, if not always money.

Tips for Flying Budget Airlines

To really get the best deals on budget airlines you should sign up for emails, act quickly and open your mind to unplanned destinations. Also, just because budget airlines are considered “no frills” doesn’t mean you can’t bring your own frills onboard.

Sign Up for Deal Alerts

“Allegiant, Southwest, JetBlue, Spirit, all those domestic budget airlines have different fare sales that happen every four to six weeks,” travel blogger Ruiz said. “Allegiant has a lot of $19 one-way fares and Southwest has $50 flights. That happens all the time when they are trying to sell unsold seats.”

Travelers can sign up with each low-cost airline and get email alerts about cheap flights, with the option to tailor them only to places they want to travel.

Try Budget Airlines in International Destinations

There are many European budget airlines that allow travelers to easily get to other destinations within the continent.

“If I find a good deal anywhere in the vicinity of where I want to go, I take it,” Ruiz said.

For example, instead of paying $700 to $1,400 to fly round-trip from New York to Paris, snag a $300 round-trip fare to Barcelona instead for half the price. “There’s easy access from Barcelona to Paris and other major cities,” she said.

Try flying budget airlines within the same country, too. “I once flew from Athens, Greece, to Santorini for $9,” Ruiz said.

Snag Deals Quickly to Save Money

When Ruiz sees a great deal to international destinations, she doesn’t take the time to map out the rest of her trip. She buys the flight that gets her across the ocean before it’s sold out, then books the shorter flights to transport her throughout the region.

Deals to look out for include Frontier’s GoWild! All-You-Can-Fly Pass, which is a one-of-its-kind deal that allows for a year’s worth of flights— with some limitations— for a base price of $299 a year (on sale). Its price can change, so if Frontier is the airline for you, it’s a hard offer to beat.

Expect More Direct Flights to Fun Places

Because bigger airlines offer more flights, they tend to operate on a hub-and-spoke model with multiple legs and connections to get from point A to B to C to D. Discount airlines with fewer planes focus more on just getting from point A to point B, said Keyes.

“They can be more direct and take less time, depending on where you are going,” he said. “If I’m going to fly to Vegas for the weekend I would spend twice as long on a flight on American,” he said.

Also, since leisure travelers are more sensitive to price than people flying for business, budget airlines cater mostly to that audience, he said.  “You’re going to see more budget airlines flying to travel destinations like Las Vegas, Hawaii or Fort Lauderdale,” he added.

What to Bring on Low-Cost Carriers

Some low-cost carriers charge for blankets, earphones and food. So bring your own snacks and earphones for in-flight entertainment, Ruiz advised.

It’s also smart to wear an extra coat or sweater to use as a blanket. Don’t pack it in your carry-on, though, because you need every ounce of space there for clothes to avoid checked baggage fees.
