What the record says about this route
Which airline you fly changes the odds here. Qantas arrived on time 22.2 points more often than QantasLink over the same period on the same route — same airports, same weather, same air traffic control. A gap that survives all of that is about how the two airlines are run.
The season swings this route hard. In May it ran 29.4 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.
This is one of the heavily flown routes in the record — 11,519 flights in the period. Frequency is itself a form of insurance: when a flight goes wrong there is another one within hours, which is not true of the thin routes elsewhere on this site.
Flights from Melbourne to Adelaide run late more often than the average route, though not severely.

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