Travel was already horrible after 9/11 and the idiotic anti terrorism rules.
The myriad of different covid regulations make traveling ridiculously hard, even for people who are vaccinated, at least in Europe.
I was planning a multi countries trip and I gave up after a week of trying to find reliable testing facilities for a good price, matching with flights, matching with Airbnbs. My stomach ulcer started to act up because of the extra stress so I decided to avoid the pain.
We'll just book a one way flight, do one stupid test, cross one border, stay in one country and book everything last minute after we know we passed whatever idiotic rules are valid at the moment.
