Travel will only improve in 2022 once borders start to open up. Let's say, you are successful in getting AZ vaccine. And lets say your dose will be given to you on July 1st. 2nd dose 3 months later, Oct 1st. Now there is talk to delay second dose so more people will get at least 1 dose. So say you get your second dose in November. There are many others not ýet vaccinated. That is why only in 2022 we will see improvement.

Waiting for quarterly report.
