Etihad Airways Partners members Air Seychelles and Air Serbia have expanded their codeshare agreement, which was initially came into effect last July. The Mahe-based airline will add its "HM" designator code onto Air Serbia's flights from Belgrade to Amsterdam, Dusseldorf and Vienna. It complements Air Seychelles existing codeshares on Air Serbia flights from Belgrade to Moscow, Prague and Paris. The Serbian carrier already has its designator code and flight numbers on Air Seychelles' services from Mahe to Abu Dhabi, Johanesburg, Paris and Praslin. Etihad Airways has a 49% stake in both airlines.
