Round-Trip Fares

Search for round-trip flights. Takes the same parameters as one-way, plus a return date.

POST/api/fares/round-trip

Request body

Parameter	Type	Required	Description
return_date	string	Yes	Return date in YYYY-MM-DD format. Must be on or after departure_date.
return_time_range	object	No	Filter return flights by departure/arrival hour. Same format as departure_time_range and uses local time for the return leg's airports.

return_time_range follows the same local-time rule as outbound filters: departure fields use the return leg departure airport's local time, and arrival fields use the return leg arrival airport's local time.
