But it’s still a bumpy ride for the cabin engineers who have to strap in for manoeuvres that are ‘outside the normal passenger regime’, including a dive and the deployment of the oxygen masks.

Those strapped in for the ride include people like Technical Services Engineer Chit-lam Li and Senior Cabin Programme Engineer Katie Man, who says: ‘The first two to three days are the most important for us.’

Armed with a checklist, tape measure and torch, the team inspect every aspect of the A350-900’s cabin. If the team spots a snag, they log it and mark it with green tape. Airbus personnel then attend to it overnight. By the fourth day the team will start the ‘buy-back’, which means they are checking the items that Airbus has repaired. ‘If the cabin is clear of green tags then the defects are done,’ says Li.

It’s a tight schedule and hard work. Man says: ‘In Business Class, the seats have so many functions, so there are a lot of things to check. Although Premium Economy is smaller, there are still a lot of seat functions, and you have to do everything manually. It’s like being at the gym!’
