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.
