I enjoy simulating long-haul routes and I found this story very interesting. From US News & World Report, "World's Longest Flights"

I sometimes fly New York-to-Moscow via, yes, Aeroflot, about 10 hours, and that's more than enough for me, in real life anyways.

The longest of them all in miles:

Newark to Singapore on Singapore Airlines

-- Miles: 10,371
-- Scheduled Duration: 18 Hours


From Newark to Singapore, travelers aboard this 18-hour jaunt receive some much-needed pampering. For this long voyage, Singapore Airlines (SA) employs an Airbus 340-500. Normally holding more than 300 passengers, SA's luxury aircraft hosts only 100 seats. But to call them "seats" is really unfair; they're more like beds. Set in a 1-2-1 configuration (one at each window and two in the middle), the reclining chairs offer immediate access to the aisle. Should you be on this flight, you'll want to get up and move around, especially in the direction of the self-service snack bar. After all, you're on the longest flight in the world by distance.
