The reveal will take place on Monday April 7th at Airbus' new Cabin Design Centre in Hamburg, where airlines with orders for the A350 will choose the fitout for their planes from tip to tail.
This 'one stop shop' facility, similar to Boeing's 787 Dreamliner Gallery in Seattle, includes 'showrooms' for a wide range of pre-approved seating from economy to first class, galleys, toilets and cabin equipment plus cabin design studios.
Airbus' order book for the A350 currently stands at some 38 airlines and leasing companies with 824 aircraft between them.
Qatar will be the A350's worldwide launch customer, with its first plane due to debut before year's end.
At an international Airbus press conference in June last year, A350 program director Didier Evrard told Australian Business Traveller that "for the first customer (Qatar) the cabin is fully defined, we have modelled everything to a level that has never been achieved before."
However, South America's LATAM Airline Group – comprising Chile's LAN and Brazil's TAM – has already afforded a sneak peak of their common cabin and seating designs for their shared Airbus A350 and Boeing 787-9 Dreamliner fleets to begin flying from 2015.
