(CNBC) — The Justice Department is investigating whether airlines are colluding to grow at a slower pace as part of an effort to keep airfares high.
The government has requested information from airlines as part of the antitrust investigation. United Airlines confirmed that it received a letter from the DoJ as a part of an investigation and said it is fully complying.
Justice Department spokeswoman Emily Pierce confirmed Wednesday that the department was investigating potential "unlawful coordination" among some airlines. She declined to comment further, including about which airlines are being investigated.
