Passenger history milestones
Recorded milestones use this city-pair passenger series, with both directions combined. A first positive record is not a service-launch date; complete calendar years require all twelve observed, non-null months.
The route
Distances are true from Sydney; the ring marks the distance to Colombo.
How long is the flight?
Scheduled flight time from Sydney to Colombo is 11h 15m gate to gate, over 8,760 km. Coming back takes 10h 5m — a difference of 1h 10m, so this direction is the slower one.
Scheduled block time — gate to gate, not time in the air — taken from the current timetable for this leg. Long-haul flights are often timetabled differently in each direction because of winds aloft, so the return is not always the same length. Check your own booking for the flight you are taking.

How full were the flights?
Inbound load factor, read as a floor rather than an exact figure. Some flights on this pair also carried passengers to and from other cities, and their seats cannot be split between those journeys. Dividing by every seat on every aircraft that touched the route gives the lowest the true figure can be, so actual occupancy is at or above the line. Seat data begins in 2009, so this series is shorter than the passenger chart above.
