There was also a time early in the pandemic where planes and airports were ghost towns. By the time appreciable air travel returned, mandates were in place. Now, with near-2019 passenger counts, it might be too soon.
If things continue to improve, I could see the tipping point occurring in September. But we’ll be struggling to have hit 60% of the total population fully vaccinated by that point, so I understand the hesitancy some feel in lifting the mandate too soon.
For the record, I do intend to fly masked for the most part going forward. Maybe with a longer drink/snack break than currently allowed. It’s not as uncomfortable as I expected it to be, and I hate vacationing with whatever crud I “always” pick up flying.
