min_hours_at_destinationinteger nullable

Same-day round trip only (return_from equal to date_from): minimum hours between outbound landing and return departure. Offers with a shorter layover are excluded.

max_return_hourinteger nullable

Same-day round trip only (return_from equal to date_from): latest local hour the return may land on the calendar day after departure (e.g. 2 = home by 2 AM) before it is filtered out. Defaults to 2 so a real same-day round trip whose return crosses midnight by an hour or two is not silently reported as zero results. Same-day evening landings (before midnight) are always kept regardless of this value. Pass 0 to require a strict same-calendar-day return.
