Aha, of course! OK, if those are nautical miles this does make much more sense — 3698nm is 280 nautical miles (320 miles) longer than the great circle route.

Aha, of course! OK, if those are nautical miles this does make much more sense — 3698nm is 280 nautical miles (320 miles) longer than the great circle route. It's a bit longer than the naive calculation I made — increasing the average speed (and time at cruise) a little bit, too. Then the BAH-LHR leg is more interesting too — its great circle route is 2754 nm, so they're going 366 nm (420 miles) out of their way. Their listed distance is approximately what it'd be if they routed through the Mediterranean over Malta. https://www.greatcirclemap.com/?routes=BAH-LHR%2C%20BAH-MLA-LHR&unit=nm https://www.greatcirclemap.com/?routes=BAH-LHR%2C%20BAH-MLA-...
