I’d love to have these features like a Hub for Freight or DHL or other Companies, to have a wider range of possibilities to build your airport. Maybe put quests up for that, signing new contracts, etc. Even Hangars for Airplanes could be involved, new cars, Companies, streets
Why it should be implemented:
Maybe not everyone wants to play just with passengers. It should be implemented, because nearly every big airport I know has these features.
There are indeed already some other entries here, here and here
AFAIK the devs will take the votes on similar requests and add them up, but to keep the feature request list ‘clean and simple’ and make it easier for people to decide where to give their vote to, it’s better to not overflow with the same requests.
May just providing extra air freight for the normal passenger planes would be interesting too as an extra income. Many large passenger planes do carry air freight as well. So a second baggage cart would pick them up or bring them to the plane after the passenger luggage has been unloaded/loaded.
