The joke of the year.
I'm a serving Emirates pilot and, if the weathers ok, we carry minimum fuel just about everywhere, ESPECIALLY Europe and the US.
There are a number of ports from which we tanker fuel IN to Dubai from, as it's cheaper!!
Maybe some tons of extra Fuel from DXB? For the rain or for the price?
The rain- At times our dispatch is a little conservative when it comes to winter weather. HOWEVER they are just as likely to order tons extra OUT of Europe IN to Dubai at the slightest hint of Fog.
In short- you have no idea what you are talking about....
