Easyjet passengers departing from London Gatwick can now use mobile boarding passes, following a successful trial.
The technology allows passengers to check-in in less than ten seconds, the airline claims, and is now available for around 85 per cent of the Easyjet network.
It works by downloading and storing boarding passes on an iPhone or Android device.
Easyjet marketing director Peter Duffy said: "More than six million people have now downloaded the Easyjet app to buy flights and get the most up-to-date information about their travel.
"Giving passengers the option of mobile boarding pass technology is another way for us to make flying with Easyjet as easy as possible."
The move follows a four-month trial at six airports — Stansted, Southend, Manchester, Edinburgh, Amsterdam and Nice.
It is the latest in a run of Easyjet initiatives, including the roll-out of allocated seating last November (see news, September 2012) and its Missed Flight Cover insurance plan (see news, July 2012).
Easyjet claims that over half a million mobile boarding passes have been downloaded since it added this functionality to its app.
Passengers can see their status as "checked-in" or "not checked-in" and boarding passes are stored offline once downloaded, so that they can be accessed without incurring roaming charges or needing network coverage. Access is permitted from 30 days before the flight's departure to two hours beforehand.
