Thanks! Then just for my understanding: if Air France calls the new flight number AF256A (or AF256B) what is actually present in the system? Now we have 2 flights from SIN to CDG on 17JAN both are shown under AF256 number. But if I try to get a seatmap EF only returns the seatmap of a 'genuine' flight which departs in the evening and not the seatmap for the morning flight which was rescheduled from 16 January.
