In 2009, the operators of six major European airports joined forces in the SEAC Consortium (SESAR European Airports Consortium) and became a member of the SESAR JU (Single European Sky ATM Research Joint Undertaking).

The members of the SEAC Consortium are:

• Aéroports de Paris
• BAA Airports Ltd
• Flughafen München GmbH
• Fraport AG
• Schiphol Nederland B.V.
• Flughafen Zurich AG

The SEAC members operate, among others, 6 of the 10 busiest airports in Europe. Even today, those airports are already operating close to their respective capacity limits and, in the event of disruptions, have the greatest impact on the European air traffic network.

The SEAC airports bring in their specific knowhow and many years of experience in airport management into the project and are thus contributing significantly to the success of SESAR.
