The transfer system at MAN is creaking at the seams and struggling to cope with ever increasing numbers.
Quite a few transfers recently from Huston connecting to Islamabad, many from the TC USA flights going to/from all directions.
The problem is that the transfer system is pretty manual, due to transfers between terminals and a lack of Border Force staff. Some transfers have to be escorted by security staff.
Staff on the ground have no advance notice of the numbers of transfer passengers arriving on certain flights or where they are transferring to.
This is an area that has developed rather than been designed, and as such is inefficient.
