I know that SriLankan Airlines (former Air Lanka) had uninterrupted services into ZRH since 1979 and if I'm not mistaken Malaysia Airlines started services into ZRH 1989.
When did Thai, Singapore Airlines, Cathay, JAL, Royal Brunei, Korean, Garuda and other Asian carriers start services into ZRH and which one was the first scheduled Asian carrier into Zurich?
Just update the list if you know more details:
1. SriLankan Airlines (Air Lanka) - 1979
2. Malaysia Airlines (MAS) - 1989
