The system is supposed to credit within 8-hrs of the flight (not sure if that is departure or arrival) but it was quoted to me by someone in Dubai. Maybe I was drinking heavily when they told me.

Ninety-five per cent of the time, my miles post quickly (within the 8-hrs). But the last couple of trips - they haven't but it was quickly sorted out with a ph call to Dubai and they posted immediately...

I'm too impatient to wait for the silly online missing miles tool...
