The /products/seats/preview Service is used to display the read only seat map for one flight, useful for previewing seat availability. Seat map is returned without any passenger details.The flight is selected by passing the hashcode for the selected flight to the service.

The Airline can use the /products/seats/preview GET operation to let passengers preview seat availability before selecting a flight. This is typically done after a flight search, when some passengers prefer to check seat availability before selecting their flights.
