I guess after the event it would seem wise to have tankard
fuel.
Whenever there is an unscheduled out of sequence event it is best to have to ask for the least help necessary, because you will be the bottom of the pilem - end of the queue. Have enough fuel and catering to be independent of the handling agency. All they have to do is provide the pax and the baggage. They will thank you and you will be on your way in the most expeditious manner.
It's called command-manship. You are on site and make your best judgement. I'm sure RYR does not have tanker tables EMA-STN. All this is assuming fuel was available at EMA. I assume after landing at EMA they would have to refuel for the STN sector anyway, so why not do it all in one go?
I haven't read all the details about the reason for the delay. I've only picked up that someone posted it was due to lack of fuel. Can that really be true? Such a long time?
