dmf I am here in the wings awaiting a better DEC Package that includes an overseas basing!! However as someone has pointed out because EK salaries are tax free in Dubai the package would have to be in the currency where basing is and it would have to be increased hugely to allow for tax to be paid in country of abode. I am not therefore holding my breath as it would cost EK far more where as the Cathay and SQ overseas basings save them money by not paying education and accommodation allowances.
On busy rotes SQ always have a crew on standby but take a chance elsewhere that Flight Deck will not go sick at the last minute.
