RELATED: The CDC Just Banned You From Bringing This on Flights. During a conference hosted by the U.S. Travel Association on Oct. 26, Ed Bastian, chief executive officer of Delta Airlines, discussed how the upcoming change in travel restrictions for international visitors to the U.S. would create a surge at airports not seen since before the COVID-19 pandemic brought global travel to a halt. He admitted that most airlines were bracing for an “onslaught of travel all at once” as eager flyers took to the sky again, The Post reports. “It’s going to be a bit sloppy at first. I can assure you, there will be lines, unfortunately … but we’ll get it sorted out,” Bastian warned. “We’re going to have a good surge of demand, but in order to keep that surge up, we’re going to need to make it easier and easier for people to figure out what the documentation requirements are.” Bastian’s comments came just a day after the White House officially announced that it was lifting travel restrictions that have been in place for many international travelers from 33 countries. Under the current travel ban, most foreign nationals who have been in the U.K., Ireland, Brazil, South Africa, Iran, China, and 26 countries within the European Union within the past 14 days are currently barred from entering the U.S. India was also added to the list of countries in early May.

But in another interview, Alejandro Mayorkas, Secretary of Homeland Security, pushed back on the assumption that airport staff would be immediately overwhelmed. Instead, he assured that his department had already been preparing for a significant surge in the volume of domestic and international travelers as the holidays approached to avoid longer lines for travelers. “I think we’re going to be equipped to handle what we hope to be a real surge in holiday traffic,” he said.
