Everywhere on the planet, the airline industry went through a pretty tough time, during which it had to assess the available capacity and the impact on services. Several airlines and many European and Asian airports, such as Schiphol in the Netherlands and London's Heathrow, made significant efforts to better align available capacity with the number of flights being offered. The airlines made parallel efforts to lessen the impact of their activities on airport capacity, with a view to supporting their own activities and better serving their passengers.
