You guys work for an airline, you get perks from your employers in the form of free/subsidized travel for yourselves, family and friends. This is perhaps the most valuable perk any expat can have.
As for the booze, perhaps I am mistaken. I assumed that you were referring to an entitlement to buy alcohol at duty-free prices onboard or in the airport shop.
But you seem to be talking about picking up an nice Chianti in Tuscany and bringing it back to the UAE. If that is the case then you should of course have the same entitlement as everyone else (but no more!).
