After nearly 20 months of closed borders, the US finally opened to vaccinated international visitors on Monday, November 8. But transatlantic travel remains an ever changing landscape, with this week also seeing more European destinations added to the CDC’s highest risk travel category. And as European Covid cases continue to climb, one central European country is considering a lockdown for its unvaccinated population. Here’s what you need to know about pandemic travel this week: 1. The US opened to vaccinated international travelers It’s been a long time coming. Almost 20 months since the US banned many international visitors back in March 2020, fully vaccinated travelers from all over the world are finally able to return to the US. That includes travelers coming from previously banned countries including the UK, as well as EU destinations. To mark the occasion, Monday morning saw British Airways and Virgin Atlantic join forces to coordinate a historic dual airplane take-off. The rival transatlantic airlines scheduled two A350 aircraft to depart London Heathrow at the same time, with BA christening its flight BA001, a number usually reserved for the historic Concorde.

Thanksgiving travel is expected to rebound For many, the return of international travel to the US means long-awaited family reunions, and some travelers will be timing their trip with Thanksgiving on November 25. While Thanksgiving 2020 involved hunkering down at home, the American Automobile Association (AAA) predicts 2021 travel will rebound close to pre-pandemic levels. Some 53.4 million Americans are expected to travel for the holiday – a 13% increase from last year. Kathleen Bangs, a former airline pilot and spokesperson for airplane tracker company Flight Aware, shared her tips for ensuring holiday travel goes smoothly, including booking flights that depart early in the day to avoid a cascading effect of delays and cancellations, and even booking a back-up flight for extra peace of mind.

The Netherlands has moved to the CDC’s highest-risk category While transatlantic travel might be back on the table, it’s not without its complications. This week the US Centers for Disease Control and Prevention added two northwestern European countries to its list of “very high” risk travel destinations. The Netherlands and Luxembourg were joined by two archipelagos in this week’s update to the CDC’s “Covid-19 Very High” Level 4 category. On Friday the Dutch government announced a three-week partial lockdown from Saturday, limiting access to shops, cafes, restaurants and hotels. Countries are designated Level 4 if they have had more than 500 cases per 100,000 residents in the past 28 days. The CDC recommends people avoid traveling to Level 4 countries, and advises that anyone who must travel should be fully vaccinated first. There’s been a surge of cases across Europe recently, which a WHO official said is “of grave concern.” 4. Austria considers implementing a lockdown for unvaccinated people Austria, another European country on the CDC’s Level 4 list of “very high” risk travel destinations, is considering a lockdown for its unvaccinated population. Unvaccinated people in Austria are already banned from certain public places, including entertainment venues, restaurants and hairdressers. According to Johns Hopkins data, 64.3% of Austria’s population is fully vaccinated. On Thursday November 11, the Austrian chancellor Alexander Schallenberg called the vaccination rate “shamefully low.” “A lockdown for the unvaccinated means one cannot leave one’s home unless one is going to work, shopping for essentials, stretching one’s legs – namely exactly what we all had to suffer through in 2020,” he said. Schallenberg is pushing for this measure to be put in place ASAP. 5. Haunting image of coastal erosion wins Environmental Photographer of the Year 2021 This week, the winners of this year’s Environmental Photographer of the Year awards were announced at the COP26 Climate Summit in Glasgow. Taking the top spot was a haunting image by Spanish photographer Antonio Aragón Renuncio of a child sleeping in the ruins of a home eroded by rising sea levels on a beach in Togo, in West Africa. “I’m very happy. It’s a huge honor to win such an important prize,” Aragón told CNN. “Especially one that’s related to the environment, which is a topic I’ve been working on for several years and which I’m very worried about.” 6. Myanmar plans to reopen to tourists, raising one big question The Southeast Asian country of Myanmar plans to welcome back international tourists from early 2022, amid a complex domestic situation. In addition to navigating the pandemic, Myanmar is also dealing with the aftereffects of a February 2021 coup in which a military junta overthrew the country’s democratically elected government. “We are planning to reopen tourism for vaccinated tourists if plans are well-prepared for safe and convenient travel,” Zeyar Htun, deputy director of the Public Relations and Information Department at the military-run Ministry of Hotels & Tourism, confirmed to CNN Travel. The US State Department currently has two Level Four “do not visit” alerts for Burma, as it refers to Myanmar: one for its high number of Covid cases, and one for the ongoing political situation. All this raises one big question for Myanmar tourism. 7. Some travelers are turning their back on airplanes And as discussions about tackling the climate crisis wrap up at COP26, some eco-conscious travelers are turning their backs on air travel. Anna Hughes is the director of Flight Free UK, a campaign group that promotes alternative forms of travel beyond aviation. As the group starts to encourage people to sign a pledge to remain flight free for 2022, there are “two distinct camps” of travelers, according to Hughes. Find out which camp you fall in.
