What the record says about this route
The cancellation rate for the period is 2.58%, but almost all of it belongs to one month: June 2026, when 7.78% of flights on this route did not operate. Outside that month the route cancelled at around 1.02%. Whatever happened in June was an event, not the normal state of this route.
The season swings this route hard. In April it ran 37.7 points more punctual than in July — 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 shape of the lateness matters here. Flights on this route are not late often, but when they are late they are late by about 91 minutes — long enough to lose a connection or an evening. The on-time percentage looks reassuring and understates the consequence of being on the wrong flight.
The route has been getting better. The later months in the record run 14.1 points more punctual than the earlier ones, which usually means a schedule that was too tight has been given more room.
Which airline should you fly on this route?
Over January 2025 – August 2026, PSA Airlines arrived on time most often on MSN to PHL. Flights ran closest to schedule in April and worst in July.

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