The latest from the "Tower of joy and good tidings" is that from May 1 the duty free allowance for crew will be zero for crew. The good news is that there is no change for passengers

From what I see, the duty will be 50% on bottles with a receipt provided, so that AED 100 bottle of wine will now cost you AED 150. I'm not sure what the penalty will be if you "happen to lose the receipt", but I'd venture a guess and say it will be ridiculous.
