Because the same number has served different journeys, the statistics above describe only the route WN39 currently operates. Blending them would produce an average of two different flights.
Data and methodology
Calculated by FlyerIntel from 733 records of WN39 operating DAL → HOU, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
