Unfamiliar maps on flights across the Atlantic

When I flew to the United States last month for a four-week vacation (hence the silence of my daily prose), I was struck by an unfamiliar feature on the flight-path maps: the images often displayed our city of departure (Frankfurt on the way to the US; Boston on the way back) at the bottom center of the map, with the city of arrival at the top center. On the trip to the US, this put Central America at the top, with Cuba often appearing vertical rather than horizontal, as standard maps present it, while on the way back, the East coast of Greenland ran horizontally across the globe, rather than vertically.
