How long is the flight?

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.
