Britain is set to announce the green list for countries that people can travel to on holiday shortly, and will have the right procedures in place to ensure travel can happen safely, said trade minister Liz Truss on Tuesday. Hopes that Britons will be able to travel to Europe rose on Monday after the European Union recommended easing restrictions to allow in people who were fully vaccinated or from countries with a "good epidemiological situation", boosting travel stocks. read more The British government said in mid-April it would announce which countries would be open for quarantine-free travel from England in early May, ahead of a plan to allow holidays again from May 17 at the earliest. "I don"t think it will be much longer before we make those announcements," Truss told Sky News. Sources have suggested the list could be published on Friday, after local elections are held on Thursday. "People are looking to book a holiday but I would encourage people to wait until we make that announcement," Truss added. Shares in airlines and travel companies were buoyed by the EU news. TUI , the world"s largest holiday company, was up 5% in early trading, while easyJet (EZJ.L), Jet2 (JET2.L) and British Airways-owner IAG (ICAG.L) were between 2% to 4% higher. Travel companies suggest there is pent up demand. UK-based Thomas Cook, which sells holidays online, said that bookings in the week ended May 2 were up 50% on the previous week, with summer trips as well as autumn and 2022 packages all in demand. Britain"s biggest airport, Heathrow, has raised concerns that a rise in passenger numbers could lead to long queues and overcrowding at border control as COVID-19 means border staff must check multiple forms. Truss said procedures would be in place to facilitate travel safely once it restarts. "We need to make sure that we do have the set-up correct at the airports, that we do have the mechanisms right before we go ahead," she said.
