With $385 billion currently invested in global airport developments, lounges and runways are changing rapidly. It might be decades before ‘airport cities’ are developed, but we’re already seeing new outdoor spaces, retail opportunities and better logistics. What does the future of airports hold?

Once seen as merely a place to catch trains, UK stations are now taking advantage of their heavy footfall, offering quality food and leisure facilities that have begun to attract even non-travellers to these travel hubs.

In 2013, over 3 billion passengers took to the skies. As airlines aim to make flying as simple as taking the train, could everything people would normally associate with air travel – endless queues, bad food, cramped, uncomfortable seats – be about to change for the better?
