Few things can be more frustrating for travelers than airline delays. You arrive at the airport with time to spare, check your baggage and clear customs only to discover that your plane will depart later than scheduled, or hasn’t even arrived. Delays are part of traveling and can occur because of everything from staff strikes to technical faults and unfavorable weather conditions. It would be great to live in a world where everything was as punctual as the Japanese train companies and apologies are given for services leaving 20 seconds early.

If time really is of the essence, then fortunately it is possible to plan ahead and be selective with our airline choices. The team at London-based OAG are specialists in providing air travel intelligence and statistics. With their help, we’ve got the world’s three least punctual airlines according to figures released in 2018. These figures are based on data that covers 80 percent or more of an airline’s departures.
