What do airBaltic and Brussels South Charleroi have in common?

They were the best airline and airport worldwide for on-time performance in 2015.

Second best performing airline globally was Copa, with Azul third. Japan Airlines and All Nippon Airways completed the top five.

UK airlines and airports had mixed results in the annual rankings from flight intelligence specialist OAG.

Globally, Monarch was the highest placed UK airline, in 14th, followed by Flybe in 17th. EasyJet was 50th and British Airways 70th.

The EMEA region top ten was led by airBaltic, with 94% of its flights on time, followed by Finnair, Austrian, LOT, KLM, SAS, Monarch, Iberia, Flybe and Qatar Airways.

Meanwhile, best performing airports in the EMEA region were Brussels South Charleroi, Stavanger, Bergen, Cologne Bonn, Warsaw, Bristol, Hannover, Copenhagen, Moscow Sheremetyevo and Helsinki.

The top 20 best performing ‘large’ airports in OAG’s rankings was topped by Tokyo Haneda, followed by Munich, Sao Paulo Guarulhos, Minneapolis and Sydney. Notably missing out on the top 20 are London Heathrow, Beijing and Hong Kong.

“Runway capacity of course continues to be an issue for the UK,” says John Grant, senior analyst, OAG. “Heathrow and Gatwick’s OTP ratings are both down on last year, a real reflection of how far those airports are stretched for capacity.”To qualify for inclusion in the OAG Punctuality League, the OAG Schedules database must have received at least 80% of all scheduled flights to and from an airport, meaning there were some notable omissions.
