What’s the situation at the airport?
Depends on the country and the airport, but most airports will have extra processes such as temperature screenings and sign offs to declare that you are not experiencing Covid symptoms.
There are some countries, which require passengers to provide a certificate of a negative Covid test (usually taken within the last 96-72 hours) in order to enter the airport or board the plane. You should check with the airport and airline to make sure this is not required.
Due to the extra steps, some airports may be very crowded and busy, while others may still be very quiet as not too many people are flying. You may want to check the airport website or call to see if they recommend to budget extra time.
Many restaurants and food stalls at the airport have been shut. The queues at the remaining ones can be extremely long! If you have a connecting flight and would usually depend on a quick bite during your layover, you may not be able to do so! Pack a snack!
