Welcome to the forum.
I am not as optimistic as RSN, but am hopeful he is correct. Maybe with a vaccination?
My best "guess" would be a return to somewhat "open" travel might come by end of summer??????
Testing is interesting (especially BC's new aircraft regs.). Here in BC, you cannot obtain a test (to the best of my knowledge) unless you have proof of a close contact with a confirmed COVID case or you are showing at least one of the main signs and symptoms. We are only reporting about 8,000 test per day for a population of 5 million. To confound the issue, testing is not always that accurate? This new strain(s) may have an impact on this topic as well?
Here's hoping things improve and travel can "resume".
