When the "SeatSelectAllowed" parameter is not available in a fare quote response, then what factors should be considered for seat selection criteria?
We would like to inform you that "SeatSelectAllowed" is an optional parameter.
If the Seat Map data is available in the API response(https://flight.srdvtest.com/v8/rest/SeatMap), then you may display the seat map on the frontend accordingly. In case the seat map is not returned in the response, seat selection will not be applicable for that booking.
