How BA12 actually runs

Pro Flight Search has tracked every published board update for BA12 across the SIN and LHR boards: schedule changes, gate pushes and actual clocks. Usually lands ~26 min early. Based on 5 confirmed landings · 4/5 within 15 min of schedule. Pushes back late but makes up time in the air.

The verdict above is that record speaking, so it reflects how BA12 operates rather than what the timetable promises. Numbers refresh as new flights operate.
