Considérant que Finnair lui avait refusé sans raison valable l’embarquement, M. Lassooy a saisi les juridictions finlandaises pour condamner la compagnie aérienne à lui verser l'indemnisation de 400 euros, telle que prévue par le règlement pour les vols intracommunautaires de plus de 1 500 kilomètres.
Taking the view that Finnair had for no valid reason denied him boarding, Mr Lassooy brought an action before the Finnish courts for an order against that airline to pay him compensation of €400 provided for by the regulation in respect of intra-Community flights of more than 1 500 kilometres.
