What the record says about this route
The season swings this route hard. In May it ran 45.2 points more punctual than in January — 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.
Only Loganair 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.
Flights from Kirkwall to Glasgow keep to schedule more reliably than most. On a route this punctual the day you fly matters more than the airline you pick.
This is a thin route — 573 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?

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