Question to the Department for Transport:

To ask the Secretary of State for Transport, what proportion of international flights taken from the UK have been for business purposes in each of the last 10 years.

We do not hold statistics on the proportion of international flights by purpose of travel.

The table below shows the proportion of passengers at the five largest UK airports (Heathrow, Gatwick, Stansted, Manchester and Luton) who were travelling mainly for business. These airports account for over two thirds of passengers at UK airports. The estimates are based on the CAA passenger survey, which is carried out at these five airports each year.
