The British Airlines Stewards and Stewardesses Association (BASSA) is a branch of the British trade union Unite. Until 2020, it exclusively represented Cabin Crew on Eurofleet and Worldwide fleets at London Heathrow airport. However, since the merger of all the fleets into the Heathrow Cabin Crew Team, they've become the largest Cabin Crew Union at Heathrow Airport with 90% of eligible crew.
