Delay & cancellation outlook for this flight
Early read, sample still buildingConditions at BWI and HOU 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 WN545 actually runs
Pro Flight Search has tracked every published board update for WN545 across the BWI and HOU boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left a little late (~15 min) but landed about 13 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how WN545 operates rather than what the timetable promises. Numbers refresh as new flights operate.
