2007 2017
Data from International Passenger Survey
for trips made by air. Data for overseas
trips by UK residents for all modes, and
CAA DPS amalgamated airports data for
UK residents shows the same trend.
The majority of growth is
coming from those aged
16-34 and 65+.
Trips by 0-15 year olds
are stable/declining – so
the growth is not family
holidays.
11. www.creds.ac.ukTRANSPORT & MOBILITY
Age groups also differ by journey purpose
The growth in travel by 65+ group is almost all holidays. There has been growth
in visits to friends and relatives for all age groups, particularly those aged 16-54.
