Not a particularly deep analysis. Note that while I'm not necessarily vouching for OAG's data, they are big players in the travel space and I trust them a lot more than this blog. Here's the OAG report that's sketchily linked to a paywall in the article: https://www.oag.com/hubfs/Free_Reports/Busiest%20Routes/OAG%20Busiest%20Routes%202018-A4.pdf https://www.oag.com/hubfs/Free_Reports/Busiest%20Routes/OAG%... A more current snapshot from OAG: https://www.oag.com/busiest-routes-right-now https://www.oag.com/busiest-routes-right-now And finally, OAG's own blog post on billion dollar routes: https://www.oag.com/blog/billion-dollar-route-jewels-in-the-network https://www.oag.com/blog/billion-dollar-route-jewels-in-the-... Basically it was only JFK-LHR before the pandemic. Most of the other high revenue routes are probably what you should expect, although I didn't expect SYD-MEL to be quite that high. I think maybe it's because the ranking is by airline and route and Qantas might dominate that route more than other airlines would dominate international routes.
