From the amount of press this had received I am assuming it was announced after conversations with the UK as it was all over the tv. We need to start opening travel corridors again, in a controlled manner, and to first open to vaccinated people is a good start.
If there is no end in sight the airlines will be decimated.
Trouble with travel "corridors" is that travellers are still mixing freely within the airport, i.e. check in desk queues, security queues, passport control queues, shops/cafes/bars, baggage reclaim, etc. so people in "safe" corridors are coming into close contact with people from "unsafe" countries.
I'd like to see airports segregating passengers if we go back to "corridors". I.e. Terminal 1 for "safe" countries where quarantine not required, terminal 2 for others where quarantine is required. If it's going to be longer term, i.e. a year or two before covid is under control in all countries, then we need a long term solution in our airports.
