The STF was set up by Thomas Cook as part of its response to the parents of Christi and Bobby Shepherd, who died from carbon monoxide poisoning while on a Cook holiday in 2006. The aim is to prevent further tragedies via the sharing of statistics on accidents and fatalities through an independent third party.
Among those that have signed up are Tui, Kuoni, Exodus, Neilson and Trek America. Katherine Atkinson, STF chief executive, told The Telegraph, which has campaigned on the issue, that others needed to follow the example.
