In Complete Airline Schedule, we can easily see all our departures from a certain airport.
What we cannot see, is all the arrivals at a particular airport.
This would be a handy feature in checking that the arrivals are in line with hub waves. For example if I have at one hub a wave setup so that all arrivals should be shortly before or by 1200, and all departures at or shortly after 1300 to allow for a smooth transfer, I currently cannot check the arrivals in one place. I have to scroll through all the other airports that are origins to this hub to figure this out. It is now easy to miss some flights that may arrive say 1210 thus ruining the transfer possibilities.
