When I flew JKF-DXB in June, the passenger load was only 50 for the entire plane both directions. So, I had a great flight. The passenger loads are steadily increasing day by day and I think soon the plane will be crowded.
The flight crew were all young and somewhat inexperienced. However, that was not a problem because since they were young, they were eager to please. Some airline long-haul routes have flight attendants that have 25+ years experience, old enough to be a grandmother, and are totally fed-up with the job, their employer, and any passenger request. This was NOT the situation on Emirates !!! I prefer a young cabin crew that is not burned out and still enjoys the job. If they make a mistake, so what ??? They are learning.
The plane itself was a marvel. Boeing better watch out. The Airbus 777 is fabulous.
