Neptune262 TVM for the clarification re Dibba's confusing territorial status.
I believe quite a lot of tanker ships do crew changes/rotations through Fujairah - they anchor off there while awaiting a cargo rather than going through the Straits of Hormuz which immediately pushes up the insurance rates. That could provide some PAX for this airline if it does fly to the main AUH airport. Gives an alternative to a crew bus over the hills to DXB.
