Earlier quoted context omitted.

It's certainly not always the case. In planar Euclidean geometry, for any three points, if the triangle formed by those three points has all its angles less than 120 degrees, then the sum of the distances from the three points to certain points inside the triangle will be smaller than the sum of the shortest two sides. Only if one of the angles exceeds 120 degrees will one of the three points always have the shortest…

I would expect that aircraft emissions have a fixed cost + a distance dependent variable cost. Coupled with the fact that we are optimizing over a discrete set of locations, it is very possible that the optimal location is at one of the corners of the triangle.

They have variable costs that aren't dependent on the distance. Some planes take off in 10 minutes, some planes have to sit for 45 before they can take off.

This all also assumes that you will always be able to fly directly to your destination on the selected day. If you end up diverting or getting delayed, or if certain routes make that _more_ likely, then this wouldn't be a win at all.

Strange that it doesn't choose one of the locations people are in. For example, for me it chose Toronto for an international meeting even tho one of the folks attending was from New York City. Why not NYC to prevent one person from traveling. Also, you need weighting, as often there are multiple people from a location.

You can add an airport multiple times to weight for multiple people

I find the idea great, but there are a few issues with it.

The biggest ones I have found is that when there are multiple people flying from the same airport, it won't redo the math to try to find a better location.

Also it is more fuel efficient for just one to fly than two when there are only two people.

This is a really neat tool, but I'm having a hard time imagining situations where it'd be all that useful, where people from substantially different locations all need to meet in person, but don't care where they're meeting. How often does that happen? Am I missing something?

Remote-first companies encounter this problem all the time.

Do they? I feel like remote-first companies seem to enjoy having an excuse to travel to exciting destinations as a recruitment/retention perk. “We’re meeting in Kansas City because that minimizes emissions” likely doesn’t spark joy in the same way that “we’re meeting in the Bahamas because we’re cool and fun!” would.

Yeah, I saw this too. I started by choosing three locations in Russia, which put the meeting point somewhere in the middle of Russia. Then I added 10-15 departures in Europe. Realistically, the meeting point should be somewhere in Europe/Eastern Europe at that point, as there is only three departures from Russia. But the meeting point remained in middle/center Russia.
