Hi,
since 2-3 days some airplanes are shown with more than one flight route.
See screenshot attached...(the green lines)
What happens here?
I think airplanes are often shown with more than one flight route because airlines operate multiple routes to different destinations to accommodate the travel needs of passengers and to optimize their flight schedules and operations.
There not a lot of information to be gleaned from your post and the screenshot but it may show the flight planned routing and the actual route flown but its very hard to state given the lack of information available
