Copy and paste from a Forbes article…
“ Just as U.S. has lagged behind much of the world in lifting its travel ban, the country is taking a very different approach to how to screen incoming travelers’ Covid documentation. While most already-open countries have developed a national digital solution for travelers to provide their vaccine and testing information, the U.S. is instead putting the onus for Covid-credential vetting on the airlines.
“The airlines right now are the ones seen as as being the ultimate decision makers, in what approach they choose to take in order to meet the requirements,” says Stein. “Every airline is doing its own thing, they’re finding their own way.”
That means travelers coming to the U.S. will submit Covid-related documentation not to Customs and Border Protection (CBP) but to their airline. Delta Air Lines has its Delta FlyReady solution, United has incorporated requirements into the United app, while American Airlines is using VeriFLY. Some airlines are embracing wider digitization, so, for example, “if the traveler has a pass like an IATA Travel Pass or the Common Pass they can link that to the airline system,” says Stein.”

We flew AA and I completed the Verifly prior to our return but they still examined our documents, twice.
