Royal Silk Class (Business Class)[edit]
THAI's Royal Silk Class seats has been installed on THAI's Airbus A340, Boeing 777, selected Boeing 747-400, and selected Airbus A330 aircraft. The angled shell design seats have 58-62" of pitch and a width of 20-21.5". Seats have lumbar massage and are equipped with 10 to 15" AVOD screens. Prior to refurbishment, older generation Royal Silk seats on some Boeing 747-400 aircraft are sold as Premium Economy Class seats on routes to Scandinavia. A new set of Royal Silk seats is expected with the arrival of THAI's Airbus A380-800s and new Boeing 777-300ERs scheduled for delivery beginning in late 2012. The new seats will allow for a fully horizontal recline at 180 degrees.
