What dates are you implying? What date do you want? You previously stated that the 19th & 21st is full while the 20th is still open. I checked yesterday and even though it is not fully wide open, there are still seats available. You can always check the loads here. BTW I did a dummy booking on several online engines such as expedia, travelocity, etc and first is still available for purchase on SQ322 Mar 20th. Again the situation has nothing to do with the A380 being planned for this flight. They would be crazy to block seats from being sold on a flight that has high demand most of the time.
