True, but there are three, potentially overlapping, elements to consider in what is now a pretty quick-moving picture, likely to be clarified pretty imminently. Firstly, the US block on un-vaxxed travellers was extended in January – to most people's surprise, certainly the US travel industry, who'd expected it to then be lifted – but only until April 10th, theoretically another review. The take-away point, though, was that it was the shortest extension yet, possibly indicating that restrictions will be lifted immediately after Easter. It just sounded like a final belt on some last braces and the US keeping a really cautious weather-eye on the Chinese new year and the period thereafter, just in case another major wave reared up. It hasn't mercifully. Secondly, the House voted on Feb 8th (HR 185) to immediately scrap the whole ban on un-vaxxed travel anyway, not even wait until spring. The bill, though, hasn't yet reached the Senate. In any case, the White House, meantime, has declared that all Covid emergency measures – literally everything affecting the US internally and externally – will cease on May 11 regardless. So, essentially Covid-over-and-out, certainly in terms of pandemic status. Even Djokovic has basically been given the hint that he'll be okay to participate in the US Open later this year, whereas he had to miss Indian Wells.
So, it's just a case of what comes first now: the House bill reaching the Senate before April 10 (unlikely) thus immediately ending the restriction; or the ban being lifted by the CDC on April 10 (likely), and I think this may be what Cunard is expecting; or the whole sketch finally ending anyway on May 11 (a certainty). I really wouldn't be surprised, though, if the WHO declaration confirming the end of the whole emergency also comes in May, choreographed emblematically around the US ending everything. Tellingly, the DG at the WHO briefed only last week, following a first communique in September, that the pandemic will certainly be declared over in 2023.
The direction of travel (pun intended) is heading only one way, just a case of very soon, quite soon or soonish.
