Yes think with 3 class A380s probably get away with 2 air bridges.
As you say BHX have been measuring up for a new air bridge on 54C,so hopefully it will be a 3rd and not just a higher replacement.
As BHX mostly a 2 class airport a 3rd ai rbridge for 615 is preferable.
Not sure MAN will need many more 3 air bridge stands as not sure apart from EK who would fly a 380 into MAN. Current LF on Qatar or Etihad don't suggest they would be interested in such a passenger upgauge.
They would probably instead add another twin jet flight as demand increases..unless the 777-9X needs a 3rd bridge at the same level ?
