Neither. Europe is in the North, and North == good, as another slashtard noticed :-D

I don't see why you are complaining about this. Every civilization will place themselves central to the map. I grew up in North America and so the North American continent was always central with Europe etc. on the right side and Asia etc. on the left. Australia will place itself central and so will Europe (as seen here) and Asia on their respective maps. Having North at the top of the map is an international standard (to my knowledge). This has nothing to do with North being good (and therefore S being bad?)
Interestingly, as a child, I always thought that maps were the same everywhere (North America central) and so was surprised when I first saw maps from other countries. I paused a moment and realized why and that I was naive for assuming otherwise. I had wondered at that time if, to simplify things, Australia or other countries towards the Southern end of the planet, taught geography with South at the top.
Back on track, the interpretations were interesting to view. It shows us all that we perceive things in the world differently from others (as I learned so long ago with the maps)

I grew up in North America as well, specifically the East coast of Canada. All of our world maps looked just like this, with North America on the left.
Perhaps it had something to do with the British influence in Canada or maybe it's more of an East Coast, West Coast thing. I could easily see having a map with North America in the center if I was on the West Coast as parts of Asia would be closer to me than Europe.

It makes sense to put Europe in the middle, as the split then happens across the pacific, where there's great distances between landmasses, and the split occurs on or around the dateline.
I expect America to put themselves in the middle

'East up' use to be the standard on medieval maps. Hence the word 'orientation': to figure out where the orient was (even if that meant waiting for the sun to rise I guess). After the invention of the compass which points north/south, maps began to be drawn with north on top.

Well, you can never ignore the Disney factor. Or the cruise-ship factor (many fly to Florida to hop the cruises there). Florida is really big for vacations.
BUT... then you also have the fact that lots of people fly Internationally. LOTS.
And then you have to factor in business trips. LOTS of those too. Many are International, which means Boston + New York + Newark. And many are just to the big business cities: New York / Boston Chicago. Which means TONS of people from the south east are going to one of those 4 cities every day. Either from Florida, or from Atlanta.
Then you have Atlanta, a huge / busy airport hub, It's relatively close to Florida. So all of that density is adding to that blob in the south-eastern section.

I think the person that gathered the data drew one line for an airport-airport connection, rather than look at the number of flights.

Neigh-on impossible. Obviously long haul flights tend to approximate great circles, however ETOPS considerations come into it, and jet streams move on a daily basis. I believe the SIN-EWR service doesn't follow the great circle (which puts it withing 143 miles of the north pole), but follows jet streams, flying over northern europe on the to-SIN leg, over alaska on the to-NY leg. The Atlantic tracks between Europe and the North East vary on a day-by-day basis for a similar reason.

Yep. I've been wondering how air traffic affects the weather for a long time. Do the climate folks model this?
Yes. It's a subject of tremendous interest. I saw a very good presentation on this at the AIAA Aerospace Sciences Conference two years ago, looking at global data on contrail-induced clouds viewed from satellites. The data from the weeks following 9-11-2001 was particularly informative, the time when global air traffic was temporarily grounded.
There's far too much research to summarize in a paragraph or two, but my quick overview is that contrail-induced high-altitude clouds (slightly) decrease daytime temperatures (reflecting incident sunlight) and also slightly increase nighttime temperatures (reflecting outgoing IR). Overall net effect on temperature is not large, but it tends to be slightly larger in heating the polar regions (on the average, less sunlight in, so the infrared is a little more important, and a significant number of flights go over the poles). But that's my summary from a non-random selection of papers and talks I've heard, not a rigorous review of the science, though, so YMMV.

Its true that planes generally do not carry more fuel that they need for the flight (including reserves for delays, diversions, etc) in order to save fuel - carrying more fuel uses more energy, but they only dump fuel in very rare emergencies. I was on a 777 out of Narita to SFO (as a passenger) when they had to return due to a failed ventilating fan. They DID NOT dump fuel, even though they were fully loaded for a 12 hour flight.

An aviation consultant is going to be a better expert on the subject than a dog breeder, chef, or locksmith.
"Expert" is an overused and abused title in western civilization. I recently watched a show on BBC about Roy Lichtenstein. He was a 60's pop artist who copied nearly verbatim comic panels from Kirby, Kubert, Novack, and many of the best artist in comics in that day. He projected the panels and traced them onto canvas and painted them with ever so slight modification, placing special emphasis on the dot paterns used in printing.
So the snobby BBC "expert" (Alastair Sooke) debated Dave Gibbons (artist from The Watchmen) and tries to sell Dave on Lichtenstein's art being better than the originals he ripped off. Gibbons puts forth the argument that in no other field, not music or writing, would such wholesale plagerism be tolerated. You can't pass off a Beatles song as your own because you changed on or two small things. Sooke looks Gibbons in the eye and says the original artists were less talented so this is OK.
Sooke, BBC's expert, having no background or interest in comics, has written books trashing the talents of the original artists who Lichtenstein left uncredited. He describes the creations of people like Jack Kirby as "trashy" and "low" and "pulp". As an "expert" Sooke makes the argument that Lichtenstein improved the images he copied (a subjective opinion) and therefore he is the greater artist, even though Lichtenstein in his life never sold an original composition or creation of his own.
Lichtenstein's painting "WHAAM!" has sold for $10 million dollars. It is a ripoff of an Irv Novick panel from "All-American Men of War". Novick, nor any other artist, ever saw a dime from Lichtenstein.
Bottom line - the world is full of "experts". Many of them are well paid and full of rubbish.
