Cost of Domestic Airfare Surges 9.8% in Past Year, Led By Miami International and Portland International Jetport

You’re not imagining things. Domestic airfare in the past year has risen nationally and at 95 of the 100 largest airports, according to a new LendingTree study. By analyzing average domestic airfare costs through the first quarter of 2023 (the latest available at the time of our research), the study reveals an even larger 28.4% increase nationally over the past two years.

Miami International in Florida had the biggest jump between the first quarters of 2022 and 2023, with prices increasing 23.9%. And two airports have an average ticket price above $500 in 2023: Dane County Regional-Truax Field in Wisconsin and Ted Stevens Anchorage International in Alaska.

“Assume that airfares will keep going up and plan accordingly,” says Matt Schulz, LendingTree chief credit analyst, citing the economy’s continued inflation struggles. “If you’re saving today for a dream vacation in the next year or two, try to save a little more than you think you need to.”

Key findings

• The average cost of a domestic plane ticket was $381.55 in the first quarter of 2023, up 9.8% from $347.56 in the first quarter of 2022. The average airfare cost was up 28.4% from $297.24 in the first quarter of 2021.
• Miami International in Florida saw a 23.9% jump in the average cost of a domestic flight between the first quarters of 2022 and 2023. Airfare costs there spiked from $297.36 to $368.31 — the highest percentage increase across the 100 largest airports. Portland International Jetport in Maine saw the next-biggest jump at 22.3%, while Southwest Florida International and Long Beach Airport in California tied at 18.9%.
• Just five of the 100 largest airports saw the average cost of a domestic plane ticket drop between the first quarters of 2022 and 2023. The average airfare cost dropped 8.3% at Westchester County in New York, from $402.28 to $369.08. Three Hawaii airports and Metro Oakland International in California followed.
• The most expensive airport to depart from is Dane County Regional-Truax Field in Wisconsin, where the average domestic ticket costs $537.70. Just one other airport — Ted Stevens Anchorage International in Alaska — averages more than $500. Meanwhile, the most affordable airport to fly out of is Orlando Sanford International in Florida, with an average ticket cost of $143.03. The airport beat St. Pete Clearwater International, also in Florida, by an average of 24 cents.

Cost of domestic plane ticket has risen 9.8% since 2022 and 28.4% since 2021

Our analysis of average domestic airfare costs shows significant quarterly ups and downs since the start of the coronavirus pandemic in early 2020. But in the past year, between the first quarters of 2022 and 2023 (the latest available), there was a 9.8% increase.

The jump in airfare costs between the first quarters of 2021 and 2023 was even more pronounced at 28.4%, likely fueled by consumer demand as people want to travel as the pandemic slows.

“It clearly proves how much Americans love to travel,” Schulz says. “Once people started to feel safe about traveling again after the darkest days of the pandemic, the floodgates opened and people headed to the airport in droves to make up for lost time.” And, he adds, that rush hasn’t slowed, even in the wake of soaring airfare prices and rampant inflation.

Keeping things in perspective: When you consider historical airfare data back to 1995, today’s prices (adjusted for inflation) aren’t so bad. Here’s a full look:

Where domestic airfare costs jumped the most — and where they decreased — between 2022 and 2023

Our review of airport-specific changes in airfare costs between the first quarters of 2022 and 2023 shows the most significant jump was at Florida’s Miami International. There, domestic airfare costs jumped 23.9% from $297.36 to $368.31. Right behind was Portland International Jetport in Maine at 22.3% — the only other of the 100 largest airports with an increase of at least 20%. Southwest Florida International in Fort Myers and Long Beach Airport in California tied for third with an 18.9% increase.

Meanwhile, the main runway at Maine’s Portland International Jetport was shut for eight weeks starting in the second quarter of 2022. Airfare costs at the airport skyrocketed 22.1% between the first quarter of 2022 ($368.23) and the second ($449.60).

At the two airports tied for the third largest increase, the biggest jump in the year analyzed also came between the first two quarters of 2022. At Southwest Florida International, airfare costs jumped 20.9% from $310.21 to $375.18 in this period. Meanwhile, at Long Beach Airport, airfare costs jumped 23.5% from $239.57 to $295.94.

On the other end of the spectrum, five airports had a decrease in airfare costs over the same period. Westchester County Airport in White Plains, N.Y., had the most significant drop of 8.3%, followed closely by three Hawaii airports: Kahului, Lihue and Ellison Onizuka Kona International at Keahole. Rounding out the bottom five is Metro Oakland International in California, which was down just a half percent.

For Westchester County, it could be part of a course correction. Airfare costs here spiked 34.8% the year before, from $298.41 in the first quarter of 2021 to $402.28 in the first quarter of 2022.

Most expensive (and most affordable) airports to fly out of

Price fluctuations aside, travelers want to know how much flights will cost them, which is why the study also looked at airport-specific airfare costs as of the first quarter of 2023. (As a reminder, this was the latest available period at the time of research.)

Leading the way with the highest domestic airfare costs are Dane County Regional-Truax Field in Madison, Wis., and Ted Stevens Anchorage International in Alaska — both of which cost more than $500 a ticket.

Smaller airports like Dane County may find it tough to compete with larger airports with more carriers and flights operating. On the other hand, Ted Stevens Anchorage International is the largest airport in Alaska and the third-largest cargo airport in the world, but high prices over the past couple of years have been attributed to everything from higher fuel costs to high demand.

As for less expensive flights, the lowest in the nation are in Florida — Orlando Sanford International and St. Pete Clearwater International. What’s likely helping to keep costs down at these two smaller airports is that a good portion of their flights are with the lower-cost carrier Allegiant.

How to find cheap flights in 2023

Saving money on air travel in 2023 is certainly easier said than done, Schulz says, but it can be done with a little research and savvy money moves.

• Be flexible on airport and date/time. Flexibility is essential when looking for cheap flights since costs can fluctuate widely if you’re willing to fly at an odd time or from another nearby airport. “If you have some wiggle room when it comes to travel days, times and destinations, you can save yourself some real money,” Schulz says.
• Leverage airline miles/points. Points and miles can make a dream trip a reality for budget travelers, Schulz says. You’ll need to use them wisely to get the biggest bang for your reward buck — you can even score a free flight if you accumulate enough points. For example, if you can travel during off-peak times, that flight may cost you far fewer miles to book than one you’d take during the busiest time of the year.
• Get a bonus when you book. If you’ve already put cash away for your trip, consider opening a new travel credit card to pay for the flight — and then pay it off right away, Schulz says. “That way, you can take advantage of that card’s rewards, including a potential sign-up bonus,” he says. Some card bonuses can be worth hundreds of dollars; if you don’t revolve a balance, that’s free money in your pocket.
• Take advantage of other flying perks that save money (free checked bags, etc.). Have you checked your credit card benefits recently? “Chances are that your credit card has more travel perks than you realize,” Schulz says. Do some homework to learn more about the savings your cards might allow before you arrange your next big trip. “Your card could include everything from free checked bags and priority boarding to insurance on car rentals, baggage delays and even trip cancellation,” Schulz says. Airport lounge access and a statement credit for Global Entry are nice conveniences, too, if your card offers it. The quickest way to learn what your card offers is to call the 800-number on the back of your card and ask. Doing so can potentially save you some real money the next time you travel.

Methodology

LendingTree researchers analyzed Bureau of Transportation Statistics (BTS) domestic airfare costs data at the national and airport levels.

Average fares are inflation-adjusted and based on the origin city, using data from the BTS’ Origin and Destination (O&D) survey. The airport data analyzed the 100 largest airports by total 2022 passengers. Specifically, we found the cost of inflation-adjusted domestic airfares in the first quarter of 2023 — the latest available at the time of our research. Additionally, we estimated the percentage change in average domestic airfare costs between the first quarters of 2022 and 2023.

The data focuses on round-trip fares but includes one-way trips in which returns weren’t purchased. Fares include the price charged by the airline and taxes or fees at the time of purchase, but they don’t include fees (such as baggage) paid at the airport or on the aircraft.
