Delay & cancellation outlook for this flight
Early read, sample still buildingConditions at YUL and CUN 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.

Pro Flight Search has tracked every published board update for WS9458 across the YUL and CUN boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left right on schedule but landed about 16 min early. Not enough to call it.
