What the record says about this route
This is a late route. Flights from Dallas to Houston miss their scheduled arrival often enough that a tight connection at the far end is a connection at risk.
This route does better than its own airport. Departures from DAL overall run 12.4 points less punctual than this particular one — so whatever congestion DAL has, this route is largely escaping it.
Only Southwest Airlines flies this route in the published record, so there is no choice to weigh — the route's figures and the airline's are the same figures.
This is a thin route — 328 flights across the whole period. On a route this infrequent a cancellation is far more costly than the rate suggests, because the next departure may not be the same day.
Which airline should you fly on this route?
Over March 2025 – August 2026, Southwest Airlines arrived on time most often on DAL to HOU.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on DAL to HOU during March 2025 – August 2026, as reported by the airlines to the US Bureau of Transportation Statistics. "On time" is the federal definition: arriving at the gate within 15 minutes of the scheduled time.
A route's record is a description of the past, not a forecast. Weather, air traffic control and the aircraft's earlier flights that day drive most delays, and none of them are predictable from a historical rate. What the record does tell you is whether this route runs late more often than others, and which carrier on it has the better history — which is the part you can actually act on when you book.
Cancellations are counted separately from delays because they are a different problem for a traveller: a late flight still gets you there. How the grade is calculated →
