Business travel demand has "plateaued" but revenue continues to rise thanks to strong demand and capacity constraints, United Airlines CEO Scott Kirby told CNBC Tuesday.
Major companies, many in tech, have announced plans to cut back on spending, like business travel, or even lay off workers.
San Francisco is one of United's major hubs, along with Newark, New Jersey, Houston, Washington D.C. and its home base of Chicago.
"It feels like business travel, and this probably is indicative of pre-recessionary kind of behavior, has plateaued even though our total revenues are still going up," Kirby said in an interview with CNBC's "Squawk Box."
