Can I change or modify the PreferredArrivalTime in the Flight Search request?
No, Do not change or modify the PreferredArrivalTime. Our backend is integrated with multiple suppliers, and different suppliers have different requirements regarding the Preferred Departure Time and Preferred Arrival Time parameters.
For some suppliers, the Preferred Arrival DateTime and Preferred Departure DateTime must be passed with the same date and time value (for example: 2026-07-16T00:00:00) in order to successfully fetch their inventory. While some suppliers are more flexible and may still return results even if the arrival time is different, others strictly validate these parameters.
Since end users generally do not provide a preferred arrival time, we recommend sending both the Preferred Departure DateTime and Preferred Arrival DateTime with the same date and time(Time must be passed T00:00:00 only) value, preferably in the format:
"PreferredDepartureTime": "2026-06-26T00:00:00",
"PreferredArrivalTime": "2026-06-26T00:00:00"
Following this approach will help avoid supplier-specific validation issues and ensure that inventory is retrieved from all available suppliers.
