American Airlines said Monday that bookings are nearly back to pre-pandemic levels as more people get vaccinated, but public health leaders repeated their concern that travel will spread the virus as new reported infections grow in the United States.
CDC Director Dr. Rochelle Walensky said she had a feeling of "impending doom," and suggested that virus cases could be about to spike in the United States as they've done in several European countries.
"What we're seeing now is more travel than we saw throughout the pandemic, including the Christmas and New Year's holidays," which were followed by surges in new cases, Walensky said at a White House briefing. "I would just sort of reiterate the recommendations from CDC, saying please limit travel to essential travel for the time being."
Evidence is growing, however, that Americans are eager to drive or fly somewhere after being mostly cooped up at home for a year.
Gasoline demand is up as more Americans travel by car. At U.S. airports, Sunday marked the 18th straight day of more than 1 million people streaming through checkpoints. That is easily the most prolonged travel rebound during the pandemic, although Sunday's crowds were still 37% below the comparable Sunday in 2019, according to the Transportation Security Administration.
The strongest travel demand is for domestic and short-haul international trips. American said that as of Friday, its seven-day moving average of net bookings -- new trips minus cancellations -- was about 90% of bookings during the same period in 2019.
American said strong bookings should continue into the second quarter, which starts Thursday.
As a result, the airline expects to return most of its planes to service in the second quarter after grounding hundreds during the pandemic.
Other airlines, including Delta and Southwest, have reported that bookings began picking up around mid-February.
Separately, Bank of America said Monday that a recovery in leisure travel is now "in full swing" despite new restrictions in parts of Europe and the U.S. Centers for Disease Prevention and Control still telling people not to travel.
New reported cases of COVID-19 in the U.S. have increased 18% in the past two weeks. Through Sunday, the seven-day rolling average for daily new cases stood at 63,239, up from 53,670 two weeks earlier, according to data from Johns Hopkins University.
However, deaths declined 29% over that same period, to an average of 1,363 per day to 970 per day by Sunday.
White House officials said Monday that more than 50 million Americans -- nearly one in five adults -- are now fully vaccinated.
"We're headed in the right direction, but we can't slow down. Millions remain unvaccinated and at risk," said Andy Slavitt, a senior administration adviser on the pandemic.
