Many countries are starting to
become more flexible. Although it is not clear when all the restrictions will be completely lifted, there is no doubt that it will happen, and the more time that passes, the greater the likelihood that a vaccine will be approved.
Just because a country has a restriction today, it does not mean that the same country will have the same restrictions in a few months. In short, you can start booking your vacation now, as the restrictions of the countries are becoming less.
Cities such as Milan and New York, which were once epicenters of the virus, have now seen fewer cases than before. This shows that things are changing and the restrictions will change if we compare today's information and the information in several months.
The good news is that most hotels and airlines have very flexible policies regarding changes and cancellations, which will make travel planning much easier than before.
Some airlines allow you to book flights 12 months in advance without a cancellation penalty and most hotels offer a lot of flexibility in terms of changes.
