I am wanting to fly in July from Sao Paulo to Singapore via Dubai. However the online booking system for Emirates will not let me book the most convienient connection, saying that it is ‘unavailable’ . I cant believe that for all three classes the flight EK432 is fully booked this far in advance. The same happens if I was to book flying from the UK, any connection using EK 432 is unavaliable. Does anyone know how this works? Do I have to wait until closer the time or can I book this flight through a travel agent, or will it always be unbookable?
