"departure": "Flight %e.flight% departs on %e.departure_date% at %e.departure_time%.",
"arrival": "Flight %e.flight% arrives on %e.arrival_date% at %e.arrival_time%."

Using this template, the `joinToArray()` method returns a new array of objects with the specified structure.

1. Define the JSON template in a session variable named Template.
2. Use the joinToArray() method with the template variable:
${Flight_data}.joinToArray(${Template})

At runtime, the response would look like this:
