Delta Airlines used federal transparency laws to demonstrate how cozy the federal Export-Import Bank is with aircraft maker Boeing — and it appears officials at Ex-Im then tipped off Boeing about Delta’s open-records request.

Delta is suing the Export-Import Bank, arguing that the agency is ignoring its mandate to consider how it harms U.S. companies. When Ex-Im subsidizes Air India’s purchase of a Boeing jet, for instance, this helps Boeing, but it also helps Air India — thus harming Delta.
