Computer problems affected several airlines Monday morning at Los Angeles International Airport.
Hawaiian, JetBlue, Alaska and American airlines all reported technical difficulties Monday morning, according to a Los Angeles World Airports spokeswoman.
In a statement, JetBlue said a computer system problem might result in check-in and booking problems for some customers.
"Due to a Sabre issue impacting multiple airlines, JetBlue customers may experience issues with booking or check-in on jetblue.com, airport kiosks, or our mobile app," the company said in a statement. "We are working to resolve the issue and apologize to our customers for the inconvenience."
Operations were back to normal early Monday afternoon, according to LAX.
