That is true but the procedure to do it is quite lengthy, and of course you will have very low priority to travel, and after all emirates, DNATA, etc staff.
Traveling with your own company is really a bad joke. You can purchase firm 50% tickets and only if those tickets are available for your flight.
I would think that this is the only company in the world, where you as a pilot of this company cannot get a 10% space available ticket to travel, rather you may have to buy a full fare ticket, even if there are 20+ seats on the aircraft.
