The camera parades around on a tour of the craft, even revealing how fitters place the lavatories.
The behind the scenes footage highlights the intensity of working on the most technologically advanced aircraft in British Airways' fleet.
One change from the company's older models, is pressurisation and its internal cabin altitude is now the equivalent of 6,000ft, which is 2,000ft lower than on other aircraft.
It also features a distinctly different First class cabin, with just eight seats compared to the usual 14.
The Heathrow-based carrier is being introduced to its fleet this month.
