Trajectory-based Operation (TBO) is expected to achieve an efficient and orderly air traffic flow. In this paper, inflow and outflow airplanes to the controlled airspace are focused on and delay of flights arriving at Haneda Airport was investigated using CARATS Open Data. According to the increase in the retaining aircraft in the enroute airspace, elapsed time of each flight demonstrates the tendency to be increased. The delay is in the order of 5 to 10 minutes, which is larger than the uncertainty of flight time estimation using meteorological forecast data. Each flight is demonstrated by position versus time plot, and the plot demonstrates the delay by radar vector when the time interval between forgoing and following aircraft is short. The variation of departure time demonstrates the tendency that variation is small in the morning and becomes large in the evening.
