Yes, flight cancellations are still happening regularly
Airlines are cancelling flights at rates similar to 2023, though the reasons have shifted. Weather remains the top cause — thunderstorms, winter snow, and fog ground planes without warning. But staffing shortages, air traffic control delays, and mechanical issues also account for a steady stream of cancellations. The Federal Aviation Administration does not publish a single cancellation rate, so the numbers vary by airline, route, and season.
Summer and winter see the highest cancellation rates because of thunderstorms and snow. Regional carriers that depend on connecting hubs — like SkyWest, Republic, and Endeavor — cancel more often than major carriers, partly because a single weather event at their hub can cascade across dozens of flights. If you fly frequently or book through a regional carrier, cancellations are a real risk you should plan around.
Key Takeaways
- Weather, staffing shortages, and air traffic control delays cause most cancellations, and all three remain common in 2024.
- Regional carriers cancel more often than major airlines, and cancellations cluster around hub airports when weather hits.
- Airlines must rebook you on the next available flight at no cost, but you are not owed money unless the cancellation was within the airline's control.
- Booking a flight with a connection increases your cancellation risk because weather or delays at the hub can cancel your second leg.
- Travel insurance that covers cancellations pays you directly if your flight is cancelled, unlike airline rebooking policies.
Why cancellations happen and which airlines cancel most
The three main causes are weather, staffing, and air traffic control. Weather is uncontrollable — a thunderstorm at Denver or Atlanta can cancel 50 flights in an afternoon. Staffing shortages mean fewer pilots and flight attendants available to cover routes, so a single absence can trigger a cascade of cancellations. Air traffic control delays, which happen when the FAA cannot clear planes for takeoff or landing fast enough, also force cancellations when flights back up.
Regional carriers cancel at higher rates than major airlines. SkyWest, Republic, and Endeavor operate flights under the names of United, American, and Delta, but they have thinner margins and less flexibility to reroute planes. If you book a regional flight, check the airline code on your ticket — if it says SkyWest, Republic, or Endeavor, your cancellation risk is higher than if it says United or American directly.
Hub airports — Denver, Atlanta, Chicago, Dallas — see more cancellations because a single weather event affects dozens of connecting flights. If you have a connection through a hub, your second leg is at risk even if your first flight departs on time.
What airlines must do when they cancel your flight
The airline must rebook you on the next available flight to your destination at no cost. That flight can be on the same airline or a different one. If the next flight is more than three hours away, the airline must also provide a meal voucher and two phone calls or emails. If you need a hotel because the next flight is the next day, the airline must pay for it — but only if the cancellation was the airline's fault, not weather.
You do not receive cash compensation for a cancellation under U.S. law, even if it was the airline's fault. You get a rebooking and meal vouchers. The only exception is if you paid for a ticket with a credit card that includes travel protection — some premium cards cover cancellations — or if you bought separate travel insurance.
If the airline cannot rebook you within a reasonable time, you can refuse the new flight and demand a refund of your ticket price. This is your right under Department of Transportation rules, though airlines often push back. If you choose this route, request the refund in writing and keep copies of all communication.
How to reduce your cancellation risk when booking
Book nonstop flights when possible. A nonstop flight can be cancelled, but a connection adds a second point of failure — if either leg is cancelled, your trip is disrupted. If you must connect, choose a connection at a smaller airport rather than a major hub. A flight connecting through Nashville or San Diego is less likely to be cancelled than one connecting through Atlanta or Denver.
Avoid booking the last flight of the day. If your flight is cancelled, the next available flight may not depart until the next morning. An earlier flight gives you more options for rebooking the same day. Similarly, avoid red-eye flights — if they are cancelled, you have no daytime alternatives.
Book with a major carrier rather than a regional one when the price difference is small. United, American, Delta, and Southwest have more planes and staff to absorb cancellations. If a regional carrier cancels, you may wait longer for a rebooking.
Travel insurance and what it covers
Travel insurance that includes trip cancellation or flight delay coverage pays you directly if your flight is cancelled, regardless of the reason. Most policies pay between $100 and $500 per cancelled flight. Some policies also cover the cost of a hotel or rental car if you are stranded overnight.
The catch is that you must buy the insurance within a set window — usually 14 days of your first trip payment — and you must read the exclusions carefully. Some policies do not cover cancellations due to weather. Others exclude cancellations if you booked your flight more than 60 days in advance. A few policies require you to have a connecting flight or a prepaid hotel to may have access to.
Travel insurance is worth considering if you are flying during peak cancellation seasons (summer and winter), flying through a hub airport, or flying on a regional carrier. For a $300 ticket, insurance costs $20 to $40 and pays out if you are stranded.
What to do if your flight is cancelled
First, do not leave the airport. Go directly to the airline counter or use the airline's app to rebook. The airline will place you on the next available flight, but if you leave the airport, you may lose your spot in the rebooking queue. If the counter is overwhelmed, the app is often faster.
Ask the airline agent whether the cancellation was weather-related or the airline's fault. If it was the airline's fault, you are owed a meal voucher and hotel if the next flight is the next day. If it was weather, the airline has no obligation to pay for a hotel, though some do as a courtesy.
If the next available flight is more than a few hours away and you have flexibility, ask whether the airline will rebook you on a competitor's flight. Some airlines will, especially if they cannot get you to your destination the same day. This is not required, but it is worth asking.
Keep all receipts — meal vouchers, hotel bills, parking fees — and photograph your boarding pass and the cancellation notice on the airport display board. If you later dispute the airline's compensation, these documents prove what happened.
Seasonal patterns and when cancellations peak
Summer thunderstorm season (June through August) and winter snow season (December through February) see the highest cancellation rates. Thunderstorms are unpredictable and can ground planes for hours. Winter snow affects airports across the northern half of the country, and a single storm can cancel hundreds of flights.
Spring and fall are generally safer, though neither is immune. Cancellations also spike around major holidays — Thanksgiving, Christmas, and New Year — because airports are congested and any disruption cascades quickly.
If you have flexibility, book flights in April, May, September, or October. If you must fly in summer or winter, book a nonstop flight on a major carrier and consider travel insurance.
Frequently Asked Questions
Can the airline cancel my flight less than 24 hours before departure?
Yes. Airlines can cancel flights at any time, including minutes before departure. The Department of Transportation requires airlines to notify you as soon as possible, but there is no minimum notice period. If you are already at the airport, the airline must rebook you when ready.
Do I get a refund if the airline cancels my flight?
You get a rebooking on the next available flight at no cost. You do not get a cash refund unless you refuse the rebooking and demand one in writing, or unless you bought travel insurance. If the airline cannot rebook you within a reasonable time, you have the right to refuse and request a refund of your ticket price.
What if my connection is cancelled and I miss my second flight?
The airline must rebook you on the next available flight to your final destination. If the second flight was on a different airline, your original airline is still responsible for getting you there. Keep all receipts and documentation of the cancellation.
Should I buy travel insurance for every flight?
Travel insurance makes sense for expensive tickets, peak travel seasons, or flights with connections. For a $200 domestic flight in April, the risk is low. For a $1,200 international flight in December with a connection, insurance is worth the $30 to $50 cost.
How do I know if my flight is at high risk of cancellation?
Check the airline's on-time performance on the Bureau of Transportation Statistics website, which tracks cancellation rates by airline and route. Regional carriers and flights through major hubs have higher cancellation rates. Weather forecasts for your departure and arrival cities also signal risk — if thunderstorms or snow are predicted, cancellations are more likely.
