What is your suggestion?
Add to the player’s contract the last time the plane was handled
How would it work in the game?
When we have many planes sent to other players, it becomes difficult to monitor the performance of the contracts. When we send a plane to a player and some time later he abandons the game or stops playing at the airport, we will hardly miss that plane and it may be forgotten among other contracts, causing us to “lose money.” If we had a date that informed the last time that plane was handled or the last time that plane landed at our airport, this control would be better.
Why is this a good idea?
Usability, this will help players have better control of their active fleet
Optional: Image or reference
Something like this:
(MJust to contextualize, my game is in pt-BR and the date format I used in the example is the one used in my country: dd/MM/yyyy)
