I faced same issue with my last week travel to UAE.In Airport they are cheacking the validity of the visa even me and for my family.I have got validity for 5 months then also he gone to get approval from supervisor before issueing the Boarding pass.Once we board then we dont face any issue in UAE.
Now they make little strict i think before they dont really bother about that.... there is a rule, visa validity should be 6 months.
