The full DOJ complaint is
here. Definitely worth a read.
Of particular interest to those who focus on award redemptions, DOJ
complaint paragraph 79 claims:
"US Airways also plans to institute its fees ($40 on average) for the redemption of frequent flyer tickets on American's existing frequent fliers, who currently are not charged for mileage redemption."
This is clearly based on internal US/AA emails and other documents the DOJ has viewed.
