What is the best site for up-to-date information on Covid guidelines in Europe. In June we will be traveling to Austria, Czech Republic and Hungary. We will be flying on British Airways. As a sidenote our first European vacation using Rick Steves guide books was 18 years ago this summer.
I’d suggest using the official government sites for each country as those will be the most reliable. Here is the one for Austria:
I like the Sherpa website for a quick idea on guidelines as you travel from country to country. You can put in your starting country and your destination country to see if the rules might be different than if you were coming directly from the US to any of those locations.
In the end the links on that website do go to the official governmental site for each country.
