That`s not correct !
you can book and sell
yy F 01JAN BKK SIN
the entry in AMADEUS for this is SOYYF01JANBKKSIN
But the airlines not like to sell this ! Because the system does not count the airport taxes and fuel surcharges on these tickets ! It prices out only with the net fare ! And when checking in the agent has to check if these surcharges are paid ( and if not ) the customer has to pay them at the counter then ! Most airlines donīt have the staff who knows about that , at checkinn counters, and so they would lose these surcharges.
