It's unequivalently when I found myself stuck In front of gate at DUBAI airport. When flight gate was closed 55 min before departure of airplane. My flight was booked under NJHI3Y "fly DUBAI". All flights in words they will not close their gate before 45 min before departure of airplane but fly DUBAI dose that . I think the main reason is transportation between airplane and airports passengers. I don't why and how the gate can close 45 min when in the ticket mentioned 20 min before departure. I was in counter begging fly DUBAI Perssonal to allow us to go in .But unfortunately they rejected . I did lost my flight and I did rebooked again which cost me 3000AED for tickets.
