What the record says about this route
The season swings this route hard. In May it ran 40.4 points more punctual than in November — 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.
Cancellation, not delay, is the risk worth pricing here: 3.44% of scheduled flights never operated. A late flight still gets you there. A cancelled one leaves you rebooking, and on a route with few daily departures that can mean losing a day.
This is a late route. Flights from Chicago to Johnstown miss their scheduled arrival often enough that a tight connection at the far end is a connection at risk.
The two directions do not behave alike. JST to ORD arrives on time 7.9 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.
Which airline should you fly on this route?
Over July 2024 – July 2026, SkyWest Airlines arrived on time most often on ORD to JST. Flights ran closest to schedule in May and worst in December.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on ORD to JST during July 2024 – July 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 →
