2016 Winter Holiday Flight Cancellation Study

winter-holidays-2016While delayed flights are a nuisance, cancelled flights can ruin holidays, leaving travelers stranded for days at a time. analyzed Department of Transportation records of over 1 million U.S. flights during the December holidays (December 20 – 31) at the 50 busiest airports for holiday travel from 2010 – 2015 to identify the riskiest airlines, airports, and routes for cancellations.

Regional airline flights cancelled 3x more often

These flights are sold by a large airline like American, Delta, or United, but are operated by an independent regional airline like SkyWest or ExpressJet. The plane’s paint job and even in-flight magazine will match the parent airline, and deciding whether to cancel is also something the parent airline has a say in, but it’s officially operated by the regional carrier.

Over 4% of regional airline flights were cancelled over the holidays studied, versus 1.6% for major airline flights. Some routes operated by regional carriers saw 20% cancellation rates, illustrating how a flight on a regional sub-operator is a major risk factor for holiday cancellations.

With fewer passengers than mainline flights, the major airlines are more likely to let their own mainline flights fly and cancel regional flights when faced with a choice so fewer passengers are impacted. Big airlines are also less accountable for regional flights as they don’t count toward the parent airline’s cancellation rate when reported to the government. That is changing next year, with new rules that will require the parent airline to include regional operations in on-time statistics. They will also require more regional carriers to report statistics.

Christmas flights cancelled 5x as often as Thanksgiving

Flights around the December holidays are cancelled 5x as often as those around Thanksgiving (2.1% of the time vs 0.4% for Thanksgiving).

Spirit, JetBlue the worst among major airlines

Spirit has cancelled flights over the holidays at a rate 2x that of other major airlines, and almost 3x the rate of Southwest. Still, Spirit’s cancellation rate is below that of regional feeder carriers.

JetBlue, with heavy Northeast U.S. operations, cancelled holiday flights at about 2x the average of major airlines. JetBlue also operates many short flights on its own that are typically handled by regional carriers at other major airlines like United or Delta.

Alaska, Hawaiian the best for cancellations

With limited operations in the Midwest and East, Alaska Airlines and Hawaiian Airlines enjoy natural advantages with almost no cancellations over the holidays.

Among the global U.S. carriers, Delta leads with a holiday cancellation rate of 1.5%. Southwest enjoys a cancellation rate about half the average of all carriers.

December 26 and 27 are the worst days for cancellations

With 5% of flights cancelled from December 26 – 27, the two days after Christmas have proven costly and miserable for thousands of fliers. For fliers trying to get home before the holidays, December 23 and 24 have seen the fewest cancellations, while Christmas day is risky with a cancellation rate over 3x that of Christmas Eve.

New York’s airports and Chicago O’Hare are the worst airports for cancellations

With New York’s airports and Chicago O’Hare often seeing similar storms just days apart, they have cancellation rates over 2x the national average. Cincinnati also scores poorly with a 4.2% cancellation rate.

Newark is the worst of the worst with flights cancelled almost 3x more often than the national average, with nearly 6% of flights cancelled during the December holidays.

Honolulu, Oakland, Seattle among the best airports

With cancellation rates less than half the national average, Honolulu, Oakland, and Seattle have kept holiday plans intact.

Among major connecting hubs, Salt Lake City and Phoenix have the lowest cancellation rates at 0.9%, or 57% below the national average.

Routes to avoid

Newark to Pittsburgh, Manchester, and Washington – Reagan flights were cancelled 20%, 17%, and 15% of the time during the December holidays, a startlingly high rate over the course of over 5 years. While all of these cities are within a day’s drive of Newark, when storms strike rental cars are scarce and driving conditions are treacherous.

Tips for fliers

Be alert for regional flights when you book

If you see the words ‘operated by’ or ‘DBA’ when you’re searching for a flight or looking at your itinerary, those are the signs you’re on a regional carrier, which our analysis indicates has a significantly higher risk of cancellation during the holidays.


Regional carriers can be found operating flights on behalf of major airlines on many busy routes like Chicago to New York – LaGuardia or San Francisco to Los Angeles.

To make things more confusing, many routes include a mix of flights on regional carriers and the more reliable mainline parent. Pick the mainline flight whenever possible to minimize the risk of cancellations.

Airlines cancel regional flights more often in part because cancelling a regional flight instead of a mainline flight disrupts fewer passengers. Another consideration is that parent airlines don’t have to include regional subsidiary performance in the reliability statistics they report to the government. That’s about to change under rules recently announced by the Department of Transportation, which will require airlines to include all subsidiary ‘code share’ flights to report as part of the parent airline’s statistics. But that requirement won’t be in place for this holiday travel season.

Know where you can rebook

Southwest, Spirit, JetBlue and Frontier have no ‘interline’ agreements with other domestic airlines, so if you get delayed you can only fly one of their own later flights.

If you’re flying American or Delta, you’re in for another complication. The two airlines couldn’t come to terms on an agreement for rebooking, so if you have a cancellation, you can’t ask to get rebooked on each other’s flights. United has rebooking agreements with both American and Delta, giving you more options when delays get bad.

Don’t take the first answer

Think of getting rebooked as a negotiation. The first offer you get probably won’t be the best you can do. When cancellations strike, seats are constantly changing hands, so if you don’t like the first rebooking option you get, push for alternatives, or better yet, try again later as things shuffle.

If you’re at the airport when a cancellation hits, you should do three things at once: get in the rebooking line, dial the airline service number and start waiting on hold, and open up the airline’s app while you wait. Sometimes airline apps offer rebooking options right there.

And after you’ve been rebooked keep checking the app to see of better options open up.

You can also keep searching for flights for sale on the airline’s website. The airline won’t put you in a first class seat if there are no coach seats available, but don’t be afraid to ask for a coach seat on flights with very expensive fares. Once a cancellation strikes, just about any coach seat available for sale is up for grabs.

Use a card with the right coverage

Several travel rewards credit cards offer trip delay coverage that can pay for meals and hotel expenses if you suffer a long flight delay. When weather or air traffic congestion causes a delay, the airlines have no responsibility to do anything more than get you on a later flight or refund your ticket.


Data was collected from the Department of Transportation (DOT) Transtats database for the years 2010 – 2015. Thanksgiving flights were defined as those from the Tuesday before through the Monday after Thanksgiving, while December holiday flights were defined as those from December 20 – 31 each year.

The 50 busiest airports (defined by the number of flights during the holiday periods studied) were used to compile rankings.

Routes with an average of at least one flight per day over the years studied were considered in the route rankings.

Airlines studied included the 10 mainline carriers which report data to the Department of Transportation, as well as regional feeder carriers which report.

Regional flights are defined as those operated by airlines such as SkyWest, ExpressJet, and others which operate feeder flights on behalf of global airlines like United, Delta, and American.

Mainline flights are defined as those directly operated by the parent airline, and includes both global carriers like United and low cost carriers like Spirit.
