Up until the end of 2019, 7-year forecasts of flights and Service Units were published in Spring and refreshed in Autumn each year. For the first two years of the period covered, these forecasts included figures for each month. Details were provided for each State, or group of States and flows.
Since the start of the COVID-19 outbreak, the 7-year forecast production cycle has been slightly changed.
