Punctuality League 2019

See on-time performance results for the world's airlines and airports


Congratulations to the new winners of the 2019 Punctuality League! 

The highly-anticipated Punctuality League report is back.

Another year, another look at on-time performance for the world's airlines and airports and 2019's edition makes for some very interesting analysis, especially as sitting on top of this year's league is a brand new winner.

Dethroning 3-time winner airBaltic was no easy task, but in 2018, Copa Airlines topped the ranking as the most punctual airline in the world with OTP of 89.79%, becoming the first-ever Latin American winner of the League.

In fact, it's been a brilliant year for South America as LATAM Airlines Group came first in our Mega Airlines category with on-time performance of 85.60%, climbing a remarkable seven places and knocking Japan Airlines off top-spot. The success follows in our Medium Airports category as Panama City climbs from 3rd to 1st.

We also welcome five new entrants in the Small Airports category, with Minsk going on to claim first place, but it is Japan which continues its excellent standards by winning the Large Airport and Mega Airport categories with Osaka and Tokyo Haneda respectively holding onto the top spots.

With so many airlines and airports anticipating this report, it's no wonder the Punctuality League is being recognised as the world's definitive measurement of on-time performance. There's plenty of hot topics and discussions set to arise from these results, so make sure you're part of the action and download your very own copy using the form at the top of this page.

What is being measured?

  • Airlines: All, Low-Cost Carriers, Mainline, Mega and split by region; Asia-Pacific, Europe, North America, Latin America, Middle East & Africa.
  • Airports: Small, Medium, Large, Major and Mega.

What is the criteria?

To qualify for inclusion in the Punctuality League, the OAG schedules database must have flight status data for at least 80% of all scheduled flights operated by an airline or for an airport.
  • OAG’s definition of on-time performance (OTP) is flights that arrive or depart within 15 minutes of their scheduled arrival/departure times
  • Cancellations are also included.
  • Airports must have a minimum of 2.5m departing seats to be included in the report.
  • The threshold for airlines is ranked among the Top 250 airlines by annual Available Seat Kilometres (ASKs). Airline OTP is for arrivals only.

How is it calculated?

  • The league is based on 58 million flight records using full-year data from our Flight Status module to create a ranking of the best on-time performance (OTP) for the world’s largest airlines and airports.


We'll be hosting a Punctuality League webinar on January 17th 2019 to discuss the trending topics from this year's results.

Join OAG’s Chief Analyst John Grant and Rothna Begum, Director of Data on Thursday 17th January 2019, 3pm GMT as they present insights into 2018 performances and reflect on the changes and improvements recognised in the Punctuality League.
