Currently, it is very complicated to see and remember which aircraft type are operating one route. the reason being the airline leasing one type of aircraft to operate temporarily while waiting for new aircraft being delivered. It would be nice to have a route map type of menu listing in detail what route being operated by what type.
Example: The airline are waiting for new A220 and A320neo deliveries and temporarily leasing A320s and E175s to operate some routes. When the new aircraft came, you have to look at every aircraft and change every individual routes.
Also, in the flight list screen in the routes menu, it would be nice to have the ability to sort out aircraft type to change out the type quickly.
