On Friday, just over 2.1 million people were screened at security checkpoints across the nation, according to Transportation Security Administration spokesperson Lisa Farbstein.
It was the highest checkpoint volume since Aug. 15, Farbstein said.
For the last few weeks, traffic at airports around the nation started to wane as concerns began to rise over the delta variant, which is "more than 2x as contagious as previous variants," according to the Centers for Disease Control and Prevention (CDC).
The U.S. set a pandemic record for air travel on Aug. 1 with over 2.2 million people going through airport checkpoints, according to the TSA. However, figures throughout the rest of the month, barring a few exceptions, fell slightly, hovering right below the 2 million mark.
A recent report from Adobe Analytics last month also noted that the highly contagious variant of "has all but blunted" the industry's path to recovery.
During the first three weeks of August, bookings continued to decline at an aggressive pace as consumers starting "taking the Delta variant seriously and once again shifting their travel plans," Adobe Digital Insights lead analyst, Vivek Pandya, said.
From Aug. 1 to 21, consumers only spent $2.9 billion on domestic flight bookings, down from the $6 billion spent in June and $5.26 billion spent in July, according to Adobe.
At the current rate, Adobe expects overall spending throughout the month of August "to be significantly under July," Pandya said.
