At Leeds/Bradford, from the 'new' terminal opening in 67/8 up to the early eighties departs and arrivals were shown in a window on the outside of the Duty Office. Even in summer there were probably only 15-20 arrivals and departures.
Flight number, time and origin/destination were made up from individual numbers and letters which clipped into preformed channels. Duty officer's last job of the day was to enter up tomorrow's schedule.
Arrivals were announced by PA - (Chime) 'Air Anglia announce the arrival of flight AQ605 from Stavanger, Aberdeen and Edinburgh, passengers may be met in the arrivals concourse'. Delays, and calls to the departure gate (a door straight to the apron for domestic services) were announced by same means.
