Airline is a seating system developed with Vitra for use in public areas. It is flexible and cost-effective, easy to transport and install, and has a light, non-institutional look. The system is comfortable and capable of withstanding the rigours of public use.

The system is based on extruded and cast aluminium components refined to their minimum thickness and weight. The spine is a central beam–which requires no machining– to which individual components can be simply attached. This allows for a variety of configurations complemented by a choice of materials for both seat and back, including plywood, aluminium, and upholstery. The system offers a range of seating positions from upright and short sit to a more relaxed arrangement for longer usage.
