Each January, Europe's airport hubs report on how well they have performed in the previous year. Now that all the results are in, we can take stock of how well they have done.
London's Heathrow Airport remains at the head of the table but for how long? Passenger growth at the airport is the slowest among its European counterparts, at just 1.4% year-on-year. This sluggishness can be put down to the airport's capacity problems - it is effectively full and cannot add any new slots. Just this week, SAS sold a single pair of slots at the airport for the summer season for $60 million, showing how valuable they are.
The star performer for the year was Brussels Airport. It broke its record the most number of passengers, recording growth of 14.6% in a single year.
It is interesting to compare this year with the previous record year of 2000.
The number of flights at Brussels has actually decreased by 30% from 326,050 flights in 2000 to 231,528 flights in 2014: airlines are using larger aircraft than they did in 2000 and passenger load factor has increased.
Stockholm's Arlanda airport is also growing fast - up 8.5% year on year and growing by more than 30% over the past five years.
The airport's director Kjell-åke Westin says, "There is a significant need for expansion and development...We are intensifying the expansion of Stockholm Arlanda, and our offering of services is ever more exciting. Our aim is to be Scandinavia's leading airport."
