What the record says about this route

The season swings this route hard. In September it ran 36.9 points more punctual than in March — a difference bigger than the one between the best and worst airlines on most routes. If the date is flexible, it is worth more than the carrier.

The two directions do not behave alike. JAX to HOU arrives on time 32.3 points more often than the outbound. Delay accumulates through the flying day, so whichever direction is scheduled later tends to carry the worse record — which is an argument for booking the morning departure if the choice exists.

This is a late route. Flights from Houston to Jacksonville miss their scheduled arrival often enough that a tight connection at the far end is a connection at risk.

This route does worse than its own airport. HOU as a whole runs 14.3 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.

Which airline should you fly on this route?

What these figures do and do not tell you

Everything on this page is counted from the flights that actually operated on HOU to JAX during January 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 →
