Conditions at BOM and LHR are near their clear-air norm right now, so this reflects the route's recent baseline rather than a weather penalty. For this route and airline, under conditions like today's, over the last 90 days. This route's tracked sample is still thin — treat these as an early read, not a precise forecast.

How AI129 actually runs

Pro Flight Search has tracked every published board update for AI129 across the BOM and LHR boards: schedule changes, gate pushes and actual clocks. Usually lands ~7 min early. Based on 12 confirmed landings · 11/12 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 AI129 operates rather than what the timetable promises. Numbers refresh as new flights operate.
