Frequent jet-setters know better than to show up late at the airport.
However, travellers may often be subjected to flight delays regardless of how early they arrive.
Enter FlightStats, an aviation website which tracks flight data.
FlightStats most recently released the findings of its annual on-time performance awards for 2016. The airlines' timeliness is quantified by how soon a flight arrives at the gate within less than 15 minutes after the scheduled arrival time.
Under the Major International Airlines category which analyses the on-time arrival performance of the largest airlines in the world, KLM Royal Dutch Airlines ranked first.
Spanish flag carrier Iberia came second while Singapore Airlines took the seventh spot.
Singapore Airlines didn't make the top 10 in the 2015 list.
To determine the finalists and winners, FlightStats collates flight status and arrival data aggregated from civil aviation authorities, airlines, airports, and major airline reservation systems.
According to FlightStats, airlines must fulfil these requirements to be considered within an awards category:
1. Report total annual scheduled passenger flights
2. Report the geographical nature of their route network
3. Degree to which FlightStats is able to acquire flight status data
In 2016, 40 airlines were included in the analysis for the Major International Airlines category.
The following are the top 10 best performing airlines:
9. TAM Linhas Aereas
8. Delta Air Lines
7. Singapore Airlines
4. Qatar Airways
