The basic elements include a ‘brand signature’, consisting of the colourful symbol and associated logotype (name). THAI’s long established and widely recognised tagline “Smooth as silk”, often used in conjunction with the brand signature, highlights our philosophy of service. The connection between THAI and Thai silk has been close since the airline was founded, for instance in the use of lustrous Thai silk for cabin attendants’ in-flight costumes. Another linking element, seen in our advertising and printed material, is the specially designed ‘curve graphic’, which is symbolic of the traditional ‘Thai Wai’ gesture of greeting.
