CHICAGO (Reuters) - The websites for the three largest U.S. airlines, American Airlines (NASDAQ:AAL) Group Inc, Delta Air Lines Inc (NYSE:DAL) and United Airlines Holdings Inc were briefly down on Wednesday due to a technical issue with Google (NASDAQ:GOOGL).

"Google had a brief technical issue that impacted multiple carriers, including American," American said in a statement. It said the issue had been resolved with no impact to flight operations.

A spokesman for Google's travel business did not immediately respond to a request for comment.

Outage monitoring website DownDetector showed a spike in reports of problems, mainly related to website issues, beginning around 1:30 pm ET, with reports later tapering off.
