Birmingham. A similar traffic structure to MAN albeit on a smaller scale. One would then assume the staffing levels would be at a similar ratio to that of MAN. Do they refuse many diverts? No. Horror stories of passengers left stranded on aircraft for hours? No. Therefore, are we to presume they cope well with diverts? Yes.
Someone correct me if I'm wrong but I believe BHX refused a SQ flight last winter on the grounds that there were too many FR kites parked up for the duration and therefore no room. I also believe all the staff would have coped if there was enough room.
