Aviation analytics firm Cirium, reveals that December was the busiest month in 2021 for flights globally, totalling 2.43 million, however, the total number of flights cancelled globally between December 24, 2021, and January 3, 2022, was 59,240, some 2.4%.
Cirium’s On-Time Performance Review 2021 reveals December as the busiest month in 2021 for flights flown globally – a total of 2.43 millionOver 59,240 flights have been canceled globally from December 24 to January 3 – the most flight cancelations in December for the past decade20,500 of these flight cancelations happened over the first three days of the new yearThe big four US airlines canceled a total of nearly 7,040 flights between December 24 and January 3American Airlines flew the most flights in 2021 at around 1,850,050Hartsfield-Jackson Atlanta International Airport was the busiest global airport this year and ranked 15th in the Top 20 Global airports for on-time performance
The number of cancellations over this period is the most cancellations in December for the past decade, six times more than the cancellations in 2019 and two and half times more than 2020. A total of 20,500 flights were cancelled in the first three days of the new year.
The big four US airlines, including American Airlines, Delta Air Lines, Southwest Airlines and United Airlines, canceled nearly 7,040 flights over this period.
The cancelations are driven by the surging cases of the Omicron variant of COVID-19 and other operational challenges (including winter weather). Airlines rapidly cancelled flights due to staff shortages across crew and ground operations.
Pre-Omicron, global flights flown increased 1.5% week-over-week (December 11-17, 2021). However, global flights are now down 5% compared to the week prior, following the impact of Omicron.
There are large variances between the regions, with the US, Europe and North Atlantic down 9-10%, China up 6%, while Asia-Pacific and Middle East are flat.

“Flight disruptions affect airlines and airports differently – it depends on the availability and flexibility of equipment and resources in place to react quickly. Those that plan more conservatively will minimize their operational disruptions. Cirium monitors the level of disruption by measuring the completion factor of flights and their on-time performance,” said Jeremy Bowen CEO at Cirium.
“Cirium’s recent On-Time Performance Review shows how some airlines have focused on their operations to reduce the impact on passengers. For example, Delta Air Lines completed 99.8% of their flights from June to December 2021 and All Nippon Airways, the winner of the Global airline category in Cirium’s Review had a completion factor of 99.2%.”
Consideration is given to the carriers with high volumes of flights. For example, American Airlines flew the most flights in 2021 – around 1,850,050 – and still, its flights arrived 80.47% on time. The carrier did have trouble reinstating flight volumes after more than a year of deeply depressed demand yet completed 97.5% of its flights.
Hartsfield-Jackson Atlanta International Airport (ATL), the major hub for Delta Air Lines, was the busiest airport based on departing flights with 336,890 this year. Despite handling the most flights, it ranked 15th in on-time performance of the Top 20 Global airports.
Amsterdam Airport (AMS) was the busiest airport for international flights in 2021, with a total of 123,070 departing flights, however, it didn’t make the Top 20 airport rankings for on-time performance. Airports have experienced many variables this year in deploying comprehensive pandemic protocols, optimizing the reconciliation and collection of fees and services, and optimizing staffing.
Cirium’s On-Time Performance Review is the industry standard for airlines and airports operational performance. Cirium resumed reporting in June 2021, as flight volumes returned, with regular monthly updates that help gauge the industry’s performance in getting passengers from point A to point B, on time. Cirium’s on-time performance analysis is based on flight data from over 600 sources of real-time flight information.
