Lufthansa to introduce fourth class

Germany's Lufthansa will introduce its all-new premium economy cabin early next year, with first flights featuring the extra-wide and extra-legroom seats by mid-2014.

The German juggernaut has long resisted adding premium economy into it's three-class mix, sharing the same concerns of major airlines such as Emirates, Etihad and Singapore Airlines that this 'in-between' category would dilute the profitable bookings made for business class.

Lufthansa's premium economy cabin will represent around 10% of the total seating on each aircraft.

The airline previously described its premium economy as a "substantially upgraded economy product".
