Daily counts of air passenger departures from Home Office Advanced Passenger Information (API) data. Counts are based on amount of API data received rather than a true count of the number of passengers. 2. Data for 2020 exclude February 29 for ease of comparison to 2019 data. 3. Data on passenger departures are derived from live operational systems; Advance Passenger Information (API). These data are not designed for statistical purposes, there are known issues in producing estimates of departures from these sources. 4. API data primarily relate to passengers leaving the UK via commercial aviation routes. The data do not include those leaving by sea or train routes, by private aircraft or via the Common Travel Area (CTA). Figures for more recent periods in particular may also be subject to revision. 5. Nationality is derived from that recorded in the API. For dual nationals this may not be the same as the nationality presented at the border. Non-British nationals will include foreign nationals who are UK residents leaving the UK, dependants of UK residents, and other non-British nationals.
