The board shows flights from the latest data snapshot, rather than a complete schedule for any date. The flight card shows the local date. If tomorrow’s flight is not listed yet, check the schedule with the airline; the board’s update time does not guarantee that all of tomorrow’s flights are included.

Open the flight card. The terminal and gate are shown when they are included in the data received. An empty field does not mean that no terminal has been assigned. Check with the airline before travelling and with the airport’s own boards once you arrive.
