Airlines and airports are again being judged on the punctuality of their service as the volume of flights increases worldwide. Today, Cirium, the aviation analytics company, restarted its closely followed monthly On-Time Performance Reports.

In May 2021, Japan Airlines (JAL), Hawaiian Airlines, Red Wings and Avianca top the ranks for on-time arrivals in their respective regions. Meanwhile, Haneda Airport (HND) takes the top spot as the most on-time global airport.

For over a decade, Cirium has produced The On-Time Performance Report—the longest-standing analysis in the aviation industry—to provide insights on airline and airport punctuality and recognize those which have outperformed their peers, globally, regionally, and in their respective categories. The report was suspended in early 2020, as flights were impacted by the COVID-19 pandemic.

JAL tops in APAC
In Asia-Pacific, the top five mainline airlines for on-time arrivals in May include JAL (95.19%), ANA (94.60%), Air New Zealand (89.59%), Garuda Indonesia (87.98%) and Korean Air (85.48%). Air New Zealand operated the most flights over the month (12,570) out of the top 10 on-time airlines.

JAL has risen in the ranks from 10^th to 1^st place when comparing to Cirium’s last monthly report in February 2020. ANA has moved up from 5^th and Air New Zealand has moved up from 9^th. Some airlines that featured in the top 10 for punctuality in 2020 no longer feature, including Singapore Airlines, Cathay Pacific, AirAsia, Cebu Pacific Air and Thai Airways International.

Hawaiian leads while Air Canada rises in North America
Hawaiian Airlines continues to beat other North American carriers, maintaining top spot as the US most on-time airline on a monthly basis (on-time arrival of 93.22%). Air Canada, which did not make the top 10 in February 2020, now ranks as 2^nd—displacing Southwest Airlines, which was 2^nd in 2020. Southwest has slipped down the ranking to 9^th place; however, the Dallas-based carrier operated the most flights out of the top 10 carriers—a total of 89,297 flights. Delta Air Lines, Alaska Airlines and United Airlines take 3^rd, 4^th, and 5^th spots.

Red Wings top in Europe
The top 10 ranking for Europe unsurprisingly has seen many shifts with Red Wings taking top place in May (96.18% on-time). Since February 2020, Vueling has risen from 7^th place to 2^nd (96.07%) and Iberia has moved up from 6^th to 3^rd (95.87%). Aeroflot slipped to 5^th place, however, the Russian carrier operated the most flights in the top 10 with a total of 13,316 flights. Newcomers to the top 10 versus 2020 include KLM (4^th), SunExpress (7^th), and SAS (10^th). Airlines no longer in the top 10 include LOT Polish Airlines, Air France, and Norwegian Air Shuttle.

Avianca soars in Latin America
Avianca has soared, moving from 9^th place in 2020 to be the most on-time airline in Latin America (93.69%) for May. Azul (93.53%) and Gol (93.52%) have both moved up the top 10 ranking to 2^nd and 3^rd place, respectively.

Haneda tops global airport on-time performance ranking
In the top 20 global airport ranking, Haneda Airport (HND) achieves the top spot with an on-time departure of 96.86%. Sheremetyevo International Airport (SVO), Minneapolis-St. Paul International Airport (MSP), Detroit Metropolitan Wayne County Airport (DTW), and Philadelphia International Airport (PHL) all follow in the top five.

Over half a million passenger flights were handled by the top 20 global airports in May. This is only 4% down versus February 2020. The on-time performance of the airports has improved by 3 points.

“As flights have returned, it is a level playing field to analyze the on-time performance of the airlines and airports again—a positive sign for the industry. While the factors that cause delays—congested airspace, taxiways or connecting passengers—simply did not exist in 2020, they are likely to return slowly in 2021 and into 2022,” said Jeremy Bowen, CEO at Cirium.

“Cirium applies the most precise data analysis to develop The On-Time Performance Reports and we are delighted to announce that JAL, Hawaiian Airlines, Red Wings and Avianca rank as May’s most on-time airlines in their respective regions, Congratulations also to Haneda Airport for achieving the top spot in the global airports category.”

The data analyzed in The Cirium On-Time Performance report derives from The Cirium Core—containing more than 300 terabytes of information from over 2,000 data sources.
