Airline has said it is conducting a review of reports of cyber attacks against its computers and is taking steps to protect its customers. 

Airline spokeswoman Stephanie Hensley said in a statement on Thursday that the investigation was in the early stages. 

“The company is taking the steps necessary to address the reports,” Hensly said. 

The statement did not elaborate. 

US companies, including Delta Air Lines, JetBlue Airways and United Airlines, have reported at least one cybersecurity incident since September, according to the Federal Aviation Administration. 

A Delta spokeswoman said in an emailed statement that it had not received any reports of breaches. 

In an emailed response to questions about the report, JetTac, the airline’s parent company, said it had received a report of a cyber attack on one of its computers, but that the incident had been resolved. 

Delta spokeswoman Elizabeth Lissman said JetTec had received another report on September 6 and had immediately contacted the airline to discuss the issue. 

JetTac said it was investigating. 

According to the FAA, airlines must have at least 15 days’ notice before a breach of any system. 

It’s not clear how many of the alleged breaches involved the airline. 

U.S. and international airports are subject to a new cyber threat alert from the DHS and the FAA that allows airlines to alert the authorities if they suspect a cyber threat. 

On Wednesday, the FAA said it could not verify the authenticity of a report on the Delta Air lines cyber breach, which was posted on a web site that has been used by some anti-Trump protesters.
