Passengers at London City Airport are the eco-friendly sort, according to latest figures.
The airport's figures show a 7% hike in travellers opting to make paperless journeys in favour of using technology to check in for their flight.
The number of people downloading their boarding pass direct to their mobile phone now totals 21 per cent while the number of jetsetters visiting a manned desk at the terminal fell from 36 per cent to 29 per cent during the past year.
And more than half of all passengers are now opting to travel paperless.
Chief information officer at London City Airport Alison Fitzgerald said: “Even though we check-in for flights online, the majority of us still print out hard copies of our boarding passes.
“We want passengers to think about their journey beginning at home or the office, taking control to save themselves time and effort further down the line.
“Less time at the airport means more time to do other things.”
