Data on punctuality 2017 collected from the members of the working group ACI Europe-EAPN (European Airport Punctuality Network) highlight a slight deterioration in punctuality both for departures and arrivals compared to 2016. On average, the punctuality of departing flights was 75.7% compared to 77.9% recorded in the previous year, with significant monthly fluctuations ranging from a maximum of 83% in March and November and a minimum of 66% in July. Arriving flights recorded average punctuality of 78.6%, slightly reducing on last year (80.6%), with fluctuations in the same months as those for departing flights. Among the most significant consequences of the general increase in traffic were airport capacity problems at many airports and difficulties experienced by European air traffic controllers in managing the overall capacity of the system. Furthermore, summer weather conditions (wind and strong storms) contributed to the deterioration of punctuality data, especially at the airports of London Heathrow, Frankfurt, Barcelona, Palma de Mallorca and Nice. At European level, there were increasing delays in departures over arrivals, except at Malpensa, London Heathrow, London Gatwick and Oslo. Linate, with over 85% of punctual departing flights, ranks as the leader in terms of punctuality across all the airports in this category, ahead of the other comparable Italian airports of Bologna and Naples. With punctuality confirmed at around 80%, Malpensa ranks above the average European and is the best amongst the European airports of similar size within its group (15-to 25 million passengers) (including Vienna and Athens). It is also far ahead in comparison to the main larger airport hubs such as Rome Fiumicino, Munich and Frankfurt.
