(CNN) -- Last week Airbus announced a squeeze which will make most frequent flyers groan, but today the European firm unveiled how passengers flying on its new A350 XWB might travel.

Two test planes have been fitted out with full economy and business class interiors. The economy cabin has a nine-abreast configuration, with 18-inch wide seats, while business class has just four seats per row.

Airbus boasts that the new, extra wide-body planes will have near-vertical walls and larger overhead baggage bins compared to its current fleet of aircraft.

And for passengers with long legs, there shouldn't be any more issues with in-flight entertainment (IFE) boxes blocking the space under the seat in front of them; Airbus has placed all the electronic boxes and connections under the floor.
