For once, a clear direction(pun intended) given. The other choice is a hotel chain with countless sites(yes, there is one in Montreal, surprise).

With no beating around the bush(for a change), at the moment, the world's longest nonstop flight is the route between New York and Singapore. With a calculated distance of 15,349km and almost 19 hours of flying, the route operated by Singapore Airlines is the longest in the world.

An interesting, if not slightly different  topic for today, thank you:

Fact checking is an interesting, and sometimes, intercontinental sport. In the case of longest intercontinental flights it depends how you measure them. Do you use great circle distance between the two airports, the actual distance covered or time taken flying between the two airports. Airlines don't necessarily fly the great circle route even though it is the shortest because a longer route could be quicker because of assistance from jet stream tail winds. So sometimes they talk about distance and sometimes they talk about time in the air.

In terms of time in the air for a commercial flight the record goes to (drumbeat): The flight from Ceylon to Australia on Aug 30, 1943 remains the record holder for longest time airborne (for a commercial passenger flight) at 32 hours, 9 minutes.

During WWII, when Japan controlled much of SE Asia, Qantas operated a regular commercial intercontinental service, using Catalina aircraft, between Perth and Ceylon called "Operation Double Sunrise". The distance was  3,512 miles which shows how commercial flying has changed. An interesting note is that the current Qantas plans for long distance non stop flights are called "Project Sunrise."  

My favorite intercontinental ballistic missile is a Russian bird code-named SATAN by NATO. It is a MIRV (Multiple-Independent Reentry Vehicles) with up to a dozen warheads that can strike different targets with precision. Before the Soviet Union collapsed, there were plans for warheads to deliver chemical and biological payloads. The nuclear warheads range from 200Kt up to 1.2 Mt.

This weapon has been replaced and modernized by the R39 Sarmat or the SATAN II.

These missiles are civilization enders.
