Great flight from LHR - DXB but DXB - MEL was a total nightmare!
We were seated in the forward mini Y cabin, row 17? Anyway, the fasten seatbelt sign was on for 6 hours during the second halF of the flight, with no sign of any bumps or turbulence, just smooth air. This meant when I really needed to go to the loo I was stuck. We called the cabin crew and I asked if the sign was meant to be on, all she said was 'yes'. I have no idea why.
The temperature of the cabin went up and down, from freezing cold to baking hot in a couple of minutes, but the worse thing was the screaming children in the cabin. I know there is nothing they can do about it but there were 4 children all under 12 months old and they did not stop screaming from wheels up to touch down. Real high pitched screaming which meant no sleep on the entire flight.
This was my first trip in Y as a gold and I didn't expect any special welcome or anything, which is good, because I got nothing at all.
All in a poor experience, but still better than Delta J class ;o)
