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 airlines. But let’s quickly provide you with some facts before we dive into the details of the ranking:

Which airlines are included?
The ranking includes 288 airlines that provide data to OAG. Moreover, we only included airlines that performed more than 1,000 flights in 2021.

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

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

Most Reliable Airlines – World’s Top 20

The gold medal and award for the world’s most reliable airline in 2021 goes to Hawaiian Airlines. As one of only three airlines, Hawaiian achieved a ZERO cancellation rate from February to July 2021. Besides Hawaiian Airlines, Philippines AirAsia and Sun Country Airlines achieved the identic result. However, since Hawaiian Airlines operated the highest number of flights compared to Philippines AirAsia and Sun Country, the island carrier won the gold medal.

Moreover, it’s worth mentioning that all airlines on the top 20 delivered an excellent performance in terms of flight schedule reliability. As a result, many of the shown carriers had to cancel only a very meager amount of flights. On top of that, it is good to see airlines from all world regions among the top 20. Although European airlines represent a considerable part, we also have airlines from Latin America, Africa, the Middle East, and Asia.
