Scott Mayerowitz and David Koenig broke the story that the Department of Justice is demanding copies of communications between major airlines as part of an investigation into unlawful collusion to limit capacity and increase airfares.

It’s conceivable there were unlawful communications or signaling along the way and no doubt the Department of Justice will find that.
