How should a flight plan be handled if trading between two airports with operational control towers?

When trading between two airports that both have operational control towers, the flight plan will automatically close when the aircraft arrives at the destination airport. This is because control towers are equipped to manage flight plans effectively, and they will notify the appropriate authorities when a flight has arrived. This automation streamlines the process and ensures that the flight plan is updated accurately without requiring pilot intervention.

While it's important for pilots to be aware of their flight plans, handling the closure of the flight plan at airports with operational control towers becomes one less task on their checklist, as the tower's operations take care of this process. This feature is especially vital in busy airspace, whereby managing many arriving and departing flights effectively maintains safety and efficiency.
