As a frequent user of LTN I have to say at peak times the temp/new arrivals area is a nightmare. 8 flights on one conveyor belt the other day and with only one narrow exit point there were queues to get out.
The zebra crossing is becoming a nightmare for the busses and coaches - as customer after customer crosses. They would be better closing it and creating a new walkway around it but maintaining enough distance for the traffic - in my opinion
