DCA to HOU questions
Is DCA–HOU running on time right now?
Significant delay risk. The departure side at DCA is the weaker end, route health score 40/100. The airports section above carries the live status and delay window at both ends.
Morning or evening flight on DCA–HOU?
Operators schedule morning departures around 06:55 and evening departures around 18:55 from DCA. Earlier flights typically land before destination-airport delays accumulate later in the day; check the HOU delay card to confirm conditions when you'd arrive.
How long is the flight from DCA to HOU?
Great-circle distance is 1,959 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 168–198 min gate-to-gate on this route.
How often does DCA–HOU fly?
Southwest Airlines runs the route with about 23 flights a week (daily). Since one carrier owns the route, a single disruption tends to ripple through the day.
