A few months ago I did the longest flight of Emirates airlines. They don’t operate this flight anymore because there is a pandemic. The flight took around seventeen hours long and the cruise speed was mach 0.85. I really recommend this flight because you have a realistic ultra long haul route, some diverse and nice scenery and both airports with buildings. The flight took place on the expert server.
Very nice indeed, the flight was never operated directly and used a stopover in Kuala Lumpur but there was another flight that used a stop in Denpasar btw. Very nice pictures tho
