In my opinion all maps of single airplane routes should be shown with a two-point equidistant projection. This clearly shows the straight line between the start and end as the shortest direction, and minimizes distortion along that line. Additionally, all points on the map have accurate distances from either point, and deviations from the geodesic (such as for administrative or weather related reasons) are easily seen. https://www.jasondavies.com/maps/two-point-equidistant/ https://www.jasondavies.com/maps/two-point-equidistant/
