Scoot (TR/SCO)

Scoot Tigerair Pte Ltd, operating as Scoot, is a Singaporean low-cost airline owned by Singapore Airlines through its subsidiary Budget Aviation Holdings. It launched flights in June 2012 on medium and long-haul routes from Singapore, predominantly to China and India. Initially, Scoot's fleet consisted of Boeing 777 aircraft obtained from Singapore Airlines. The airline began to transition its fleet to Boeing 787 Dreamliner aircraft from 2015. On 25 July 2017, Tigerair was officially merged into Scoot using Tigerair's air operator's certificate but retaining the 'Scoot' brand. With the change of AOC, the airline's IATA code was changed from TZ to TR, and its ICAO code was changed from SCO to TGW, previously used by Tigerair. Its head office is at Singapore Changi Airport.
