When you go to the Price Management page for a city pair, you can mass-change all the prices for routes between those two cities.
But it would be more helpful if you could choose specific routes to include or exclude from those mass-changes.
For example, to add a 30% premium to Concorde flights (which currently I have to do manually by opening and editing every route for every day of the 7-day schedules) while keeping subsonic flights at default pricing.
Or to apply a 10% discount to Saturday flights.
Or to add a 10% premium to non-stop flights, when you have both non-stops and techstops.
This could be done in a few ways:
(A) put a checkbox next to each route, and have the price changes entered apply only to the checked routes.
(B) or, if that is too complicated to do, allow mass price changes to filter by aircraft type. or filter by non-stop/tech-stopped. In the same way that you can currently filter by class (e.g. raise economy class price only), add the option to filter by AC type or nonstop/techstop.
