seemingly missed by the Airport Commission
"Indirect travel via airports in other countries may in some cases provide an alternative to travel via UK airports. Around 10% of passengers at UK airports currently choose to make their journey via airports abroad. Whilst in many cases these indirect journeys help facilitate long-haul travel to countries such as Australia and New Zealand, a number of the most frequently accessed countries, such as United States, Italy and Germany, appear in both the top 10 lists for direct and indirect travel. Airports across the UK play an important role in providing these indirect connections through linking their passengers to other international hubs: for example, Birmingham and Manchester airports together provide more than 5,000 flights per year to Amsterdam Schiphol, 4,000 to Paris Charles de Gaulle, nearly 3,500 to Frankfurt and more than 1,500 to Dubai."
