What the record says about this route
Only United 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.
At 3,266 miles this is a long-haul route, where the arithmetic of delay differs: a long flight has hours of cruise in which to make up a late departure, so departures slip more often than arrivals do.
The Anchorage to Houston route sits close to the middle of the record — neither notably punctual nor notably late.

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