The Cirium Airline Insights Review 2020 reveals that only 30 major airlines achieved this standard pre-pandemic.

On-time performance of the top 300 global airlines significantly improved as COVID-19 reduced the number of flights in the air. In 2020, airlines only flew half of the flights flown the previous year.

“The pandemic caused a significant reduction in flight volume with airlines operating 49% fewer flights in 2020. The factors that normally cause flight delays didn’t exist, such as congestion at the airport. Overall global passenger traffic was down in 2020 by 67% from the previous year,” said Jeremy Bowen, CEO of Cirium.

Cirium’s top 10 league table for flights operated by country shows that the majority of flights were operated in the US, despite a 42% year-over-year drop in the market. China maintained its position, with only 24% of that market’s flights down versus 2019.

Japan overtook India, moving up to 3rd place as India’s flights were down 50% versus 2019. The UK was hit heavily with 67% of flights down compared to last year, moving it to 8th place from 5th. Russia moved from 10th place in 2019 to 5th in 2020 and Indonesia moved into the top 10.

“Domestic travel has recovered faster and airlines with a dominant domestic market come back quicker,” Bowen said. “That is especially the case in Asia-Pacific where recovery is more positive. The US and Europe have experienced setbacks with government-enforced restrictions and additional waves of COVID-19 affecting travel.”

Travel restrictions and the shift to more leisure travel versus business travel changed the top 10 league table for flights flown by airport extensively.

Chicago O’Hare is usually the busiest airport globally for passenger flights, however the pandemic caused a 46% reduction in flights for the airport in 2020. Three Chinese airports—Guangzhou Baiyun, Chengdu Shuangliu, and Shenzhen Bao’an—moved into the global top 10 busiest airports by arriving passenger flights.

NetBrain Technologies, Inc. today announced major new platform features that advance Agentic NetOps from an emerging category to operational reality.

Terms of the agreement remain confidential. “This outcome reflects a disciplined and consistent approach to protecting our innovation and our customers,” said Justin Ferguson, SVP and general counsel at Adtran. “We take all claims seriously, but we will not hesitate to defend ourselves when assertions lack merit. Situations like this place unnecessary strain on technology providers and divert resources from advancing networks and services. By advancing our counterclaim
