From what I have read, there is a strong belief amongst some in the medical/scientific community that the virus is still able to be carried and spread by those vaccinated to those who are not.
If this has has even the slightest possibility of happening, nothing other than very few “bubble” destinations will be open for travel in the next 6-8 or even 12 months unless the government pulls off a miracle and vaccinates the entire country, studies the effectiveness and finds no risks for reopening travel overseas by June. Basically it’s in “tell him he’s dreaming” territory.
London, the US, Japan and most other destinations at all this year in my opinion is extremely unlikely to happen, other than the odd repatriation, charter or maybe a cargo run. Hope to be proven wrong so I can get out of my sh##ty side hustle and back to the skies.
