Twin-aisle
Another name for a wide-body aircraft, describing the cabin from the crew's side: two aisles, two service flows.
Definition
Twin-aisle and wide-body mean the same aircraft; twin-aisle simply describes it by the cabin layout rather than the fuselage. Every wide-body has two aisles separated by a centre block of seats, which is why crew often use the term when talking about service and positions rather than aircraft type. There is no such thing as a twin-aisle narrow-body.
What it means for you
Two aisles change how you work: services run as parallel flows, each trolley covers its own aisle, and a colleague on the far side is out of sight for much of the service. Positions, galley assignments and evacuation drills are all built around that split, and it is the reason wide-body SEP is trained separately from single-aisle SEP.
In practice
On a Turkish Airlines A350, two economy trolleys run down the left and right aisles at once from the aft galley while the crew in the forward galley handle Business, all coordinated by the cabin chief over the interphone.
