Recently Emirates has been making some big announcements, they now have 3 very long haul flights. They are really taking over some of these long haul flights, I know someone who just tried the Brazil flight and they said it was very comfortable for 16 hours. It is a little bit more expensive then planes with stop overs. BA Flight from Kuwait to London, then London to San Paulo is cheaper then the Dubai to San Paulo for 400 KD. So sometimes it might be a little bit more expensive but still very convenient flights to have, some of these flights are booked up ahead with no availability for a few months.
