Most Reliable Airlines in 2021 – The Ultimate Ranking!

Since we’ve received so much positive feedback on our latest ranking about the world’s most punctual and largest airlines, we wanted to add another perspective today. Therefore, we’ve analyzed the reliability of the world’s airports. But let’s quickly provide you with some facts before we dive into the details of the ranking:

How do you define Reliability?
In this ranking, reliability refers to the number of canceled flights in relation to overall operated flights. Therefore, we provide you with the cancelation rate for each airport that is contained in the ranking.

Which timeframe did you analyze?
For this report, we’ve analyzed data from July 2021.

How do you cluster the airports?
In order not to compare apple with pears, we clustered the ranking according to the flight volume as followed:

  • Mega Airports: Airports that handled more than 10,000 flights in July 2021
  • Large Airports: Airports that handled more than 5,000 but less than 10,000 flights in July 2021
  • Medium Airports: Airports that handled more than 1,000 but less than 5,000 flights in July 2021
