Just because an air route is popular does not make it the most lucrative. An airline can connect two cities with multiple flights per day and still not make as much revenue as they would with a small handful of flights on key routes.

Air travel data firm OAG compiled a list of the top 10 routes that generate the most revenue and that airlines that bring in the most cash from them during a 12-month period from March 2018 to April 2019.

The rankings show that business travelers continue to be the biggest market for airlines, as seen with the number of routes on the list that connect economic hubs and the aircraft serving those routes.

London, one of the world's most influential economic hubs, was featured numerous times in the list, with service to and from the UK capital among the most revenue-generating for most airlines.

In North America, domestic routes also appeared frequently, with transcontinental routes in the US and Canada earning the most revenue for some of the continent's largest airlines.

Take a look at just which routes are the most important to some airlines. All revenue figures are estimates provided by OAG.
