Delay & cancellation outlook for this flight
Early read, sample still buildingConditions at YUL and IAH 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 AC1781 actually runs
Pro Flight Search has tracked every published board update for AC1781 across the YUL and IAH boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left heavily delayed (~47 min) but landed noticeably late (~34 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how AC1781 operates rather than what the timetable promises. Numbers refresh as new flights operate.
