But you don't need a letter to distinguish the 7 instances of "Gate 9" - the terminal designator ("Terminal 5") does that .
The letters just add an extra (unnecessary) level of addressing - just saying "Gate B9" wouldn't much help most members of the travelling public - it's not at all obvious which terminal is intended - whearas "T5 Gate 9" at least lets them know where they need to go...
