The Singapore Airshow ended today. Many attendees will be flying home from Singapore on some very long non-stop flights. Here are the ten longest by distance, compiled by Pang Yee Huat using schedule data from Cirium. (Aircraft type informaition is from a mix of FlightAware and FlightRadar24.)

Notes:
Today's Featured Map shows these ten routes. Some Featured Maps come together easily from an initial ideas; others are a struggle or simply fail to lead to a map which is worth one thousand words. This one was a struggle.
Choosing a projection was the first problem. The default for the ten paths led to a polar orthographic projection centered on the north pole which was visually interesting but overlapped the routes to New York and Newark, and clustered the five routes to Europe. Switching to a rectangular projection didn't help at all. An orthographc projection centered on Singapore was useless because all of the destinations were devoured by distant dragons lurking beyond the edge of the map. An azimuthal equidistant projection centered on Singapore vanquished the dragons but din't solve the trampling of routes, plus this projection tends to be more difficult to understand. I finally settled on the the initial polar orthographic projection as the least-bad choice.
Another problem was path colors. Featured Maps involving multiple airlines generally use a color associated with the airline, but with multiple carriers operating some of the same routes that was impossible. Well, a brief experiment with Bézier paths could have fixed that, and pulled apart some of the overlapping routes in the bargain, but that was quickly rejected as being too cluttered. The eventual solution was to use Singapore's gold for routes only operated by Singapore Airlines, and a color for the other airline if an airline besides Singapore serves the route. In the case of London Heathrow, that still left a choice between British Airways and Qantas; British Airways was chosen because they came first alphabetically (I feel your pain, Qantas) but they are also the home team at Heathrow and they have more frequencies on the route than Qantas.
Finally, the clustering of European destinations meant that the labels for the two London airports overlapped other lables. The solution to that was pure hack: a joint label for the two at a convenient location in Spain with a pointer to London. It's ugly, but it sort-of works.
There's a lot of science and math underpinning the maps, but sometimes creating maps that prove to be helpful illustrations are more art than science.
