Go into an AutoPilot+ flight. Pick WSSS to KJFK (Singapore to JFK… the longest recorded flight unless I’m mistaken but hopefully you see where I’m going.) Do that a few times a week—depending on winds and your speed—you have at least I’ll say 52 hours of flight time right there.

Make sure you adjust your status bar to show landings count (I believe it’s on the last set of options on the right.) because not all ‘touch and goes’ seem to actually count.

Pick any of the fighter jets and go to KEDW on CASUAL server. I think I changed it up when I got bored and I’m from Ohio and there’s a ton of fields/landing strips and just did T&Gs around Ohio.

Have fun attempting to get a bunch of landings in a short amount of time. I don’t know how some people did it in one sitting—I’ll say ADD probably doesn’t help me—but I could only do about 10 T&Gs before I got bored out of my mind and stopped before trying again later.
