What the record says about this route
Flights from Charleston to Houston arrive late more often than they arrive on time. At this rate lateness is the normal outcome, not the exception, and the schedule is better read as an aspiration than a plan.
Lateness here is frequent but mild: flights slip past the fifteen-minute line often, yet the average delay is only about 32 minutes. That is an annoyance rather than a broken plan, and it is a very different route from one with the same on-time rate and hour-long delays.
This route does worse than its own airport. CHS as a whole runs 26.3 points more punctual than these flights, which points at something specific to the route — the time of day it is scheduled, or the aircraft that feed it — rather than the airport.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on CHS 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 →
