We write today because our offices have received reports that airlines may be refusing to provide flight information to third-party price comparison sites, which have helped the flying public save billions of dollars. We believe this practice is damaging to consumers and potentially in violation of our consumer protection laws that promote competition in the air transportation industry. Accordingly, we urge the Department of Transportation (DOT or Department) to use its existing statutory authority to promote transparent price competition that will allow consumers to quickly and easily make good purchasing decisions.
