Summer Travel Chaos Uncovered: How to Outsmart Sky-High Flight Cancellations and Fly Stress-Free This Year

If you thought 2025 was rough for air travel, you’re not alone — it felt like airports across the country were caught in the eye of a storm. Flight cancellations shot up to their highest levels in three years, thanks to a not-so-friendly tag team of Mother Nature and Congressional gridlock. And folks, 2026 isn’t exactly rolling out the red carpet either — with cancellations still hovering high, it’s shaping up to be another challenging year for travelers. So, what’s the deal behind these sky-high cancellation rates, and which airlines are still keeping their cool? Let’s unpack the chaos and arm you with the scoop you need to navigate the skies this summer without losing your mind. LEARN MORE

For travelers, 2025 wasn’t exactly smooth-sailing at airports.

Across the country, flight cancellations climbed to the highest level in three years, as Mother Nature — and Congress — dealt airlines and their passengers a one-two punch of travel woes.

So far, 2026 has offered a bit of a headache of its own.

Flight cancellations are up

According to TPG’s Best Airlines Report unveiled on Wednesday, flight cancellations last year surged nearly 15% versus 2024, as reported by the U.S. Department of Transportation.

A big reason for the downturn: the government shutdown last fall, at the time the longest in history, during which airlines were required to cut flights at dozens of the nation’s busiest hubs, amid a critical air traffic control staffing crunch.

But the numbers aren’t looking great this year, either.

Cancellation rate elevated in 2026

Through March, U.S. airlines had canceled roughly 3.4% of all departures, according to DOT data reviewed by TPG.

If that pace of cancellations continued, 2026 would wind up being easily the worst year for shuttered flights since 2022, when airline meltdowns were pervasive as travel roared back in the wake of the COVID-19 pandemic.

Even some of the nation’s most historically reliable airlines haven’t been immune.

Delta: Strong 2025, but tough start to 2026

Delta Air Lines on Wednesday finished first in TPG’s Best Airlines rankings for the eighth straight year. It was thanks, in no small part, to its strong operational performance in 2025, typically a hallmark for the Atlanta-based carrier.

But 2026 has been a different story.

But a quarter of the way through this year, Delta’s flight cancellation rate ranked an uncharacteristic sixth in the airline industry, per DOT data, which showed Delta has lagged historically weaker competitors — even perpetual last-place finisher Frontier Airlines.

Last week, the Wall Street Journal reported the airline was working to shore up its operations and staffing ahead of the summer rush.

Plenty of curveballs

The airline industry (and travelers by extension) have faced plenty of curveballs this year, though — from an uncertain geopolitical landscape to a handful of punishing winter storms in January, which hit top Delta and American Airlines hubs especially hard.

With summer now upon us, travelers can only hope to avoid the usual waves of pesky summer thunderstorms, which regularly threaten to snarl air traffic at major hubs this time of year.

With that in mind, here are some top things to know — and ways to prepare — as you head to the airport this summer.

Which US airlines are most reliable?

Based on 2025 data outlined in TPG’s Best Airlines Report, three carriers clearly outpaced the rest of the industry when it came to key metrics like on-time performance, cancellations, baggage handling and involuntary bumps.

Allegiant Air, winner of our report’s all-important reliability category — an impressive feat even if it comes with the caveat that the budget airline operates a smaller, simpler route network than its larger competitors.
Delta which, despite its more recent hurdles, generally ran a strong operation in 2025.
Southwest Airlines, which has made vast operational improvements in recent years, all but burying memories of its high-profile holiday meltdown in 2022.

Southwest now routinely ranks among the most operationally reliable airlines in America, and that’s continued in 2026.

The carrier’s 1.1% cancellation rate to date this year, as reported by FlightAware, trails only smaller foe Allegiant (Southwest’s rate of flight delays, year to date, ranked among the middle of the proverbial pack).

Tips for traveling this summer

Here’s some of our top advice for flying this summer, regardless of the airline.

Fly in the morning if you can

Morning flights just tend to get delayed and canceled less.

Flight disruptions often climb over the course of the day, as planes (and crews) zip between cities — and as thunderstorms fire up later in the day.

The overnight hours, on the other hand, give airlines valuable buffer time to reset their operations and crew staffing. More often than not, they’re starting the day “fresh.”

So, if you can stomach the 3 a.m. or 4 a.m. alarm, flying first thing in the morning can be a major itinerary-saver.

Have the airline’s app handy, and know what it can do

Flight delays are made even worse if you have to stand in a long line or wait on hold for hours with the airline.

Keep in mind: You can usually re-book yourself — or make other reservation changes — right through your airline’s mobile app when problems pop up.

Oftentimes, you’ll see updates hit your airline’s app before the flight attendant or gate agent announces it, giving you a head start to grab open seats on a different flight.

Some airlines will also now send meal and hotel vouchers to stranded passengers through the app, too, eliminating the need to wait in a queue of any kind.

Brush up on your refund rights

If your flight is canceled significantly delayed and you choose not to travel, the airline owes you a refund for the unused portion of your trip — no questions asked — under DOT policy.

This also applies to reservations that go through a significant time change.

Just keep in mind: If you accept rebooking or other accommodations, you’re likely not due a refund.

Carry on when possible, or use tech to track your bag

Carrying your bag on board the plane remains one of the simplest ways to keep close tabs on your bag.

That’s especially true when problems arise; making a last-minute pivot to a new flight is far simpler if there’s no checked baggage to contend with.

But with the Transportation Security Administration’s 3-1-1 liquids rules still in place and long summer vacations on the horizon for many travelers, going carryon-only isn’t always realistic.

This is where bag tracking tools come in handy.

The largest U.S. carriers have had built in bag tracking services on their mobile apps for years.

But a few carriers have now added integrations with Apple’s AirTags, which can help travelers get a real-time look at where their luggage is located.

That includes United Airlines which, despite turning in the U.S. airline industry’s worst rate of mishandled baggage in 2025, offers robust AirTag bag tracking tech (and an overall stellar app).

Fuel-related cancellations? Watch your booking

While we’re not seeing mass flight cancellations as a result of the global fuel crisis, airlines have been making schedule changes in recent months.

To be clear, we’re not talking last-minute cancellations you learn of on your way to the airport; domestically, in most cases, carriers are cutting flights on lower-demand days and during quieter times of the day — such as late-night departures, domestic redeyes and flights on Tuesdays and Wednesdays.

My best advice: simply opt in to all notifications from your airline, and keep watch on any bookings you have farther out into the summer — and, moreover, the fall. If your flight is affected by a cutback, there’s a good chance the airline will immediately rebook you on a different flight.

Just remember: you don’t have to accept the new departure time. You can opt for a refund instead.
