The read on MEL
What the numbers say about flying through Melbourne Airport
Across official performance history, flights from Melbourne avoided significant airline-controlled delay about 71% of the time over 383,618 flights. That's a middling record — neither a strength nor a red flag on its own. Pair it with an elevated cancellation rate of 3.7% — worth weighing alongside the on-time figure. When a departure does run late, the typical delay is around 0 minutes.
On weather, Melbourne is an unusually calm-weather airport year-round. April is the calmest stretch for flying, scoring 98 out of 100 for favorable conditions, while November is the most disruptive at 96, driven mainly by low visibility & fog and high winds. The year is relatively steady, so no single month stands out as one to avoid on weather alone.
If you're connecting through MEL, give yourself room. A domestic connection wants at least about 45 minutes, and international transfer wants roughly 90 minutes once immigration and a bag recheck are in the mix. Those are floors, not comfortable buffers — one inbound delay can erase them, so add margin when the connection matters.
None of this guarantees your specific flight — it’s the backdrop. To turn it into a booking, score real flights to Melbourne, read how we weigh it all in how the PlaneSane Score works, and brush up with how to pick a reliable flight and avoiding weather delays.
