Aviation
We are familiar with airline law as Constantin has dealt with cases in this area for almost 30 years and is well connected with international instances and organizations. He has defended the interests of the Swiss flying industry ever since then and established the first subsidiary in the EU of the Swissair group. He is an expert on ground handling and dealt extensively with IATA and its TAC Travel Agency Commissioner in Stockholm. Constantin was also a member of the board of a Swissair group airline and of several subsidiaries of Swissport.
