The federal government won’t fine United Airlines for the forcible removal of a ticketed passenger from an overbooked flight last April, an incident that prompted the carrier to implement a slew of policy changes.

That’s according to a May 12 letter from the Department of Transportation to United [PDF] — which passenger advocacy group Flyers Rights obtained through a Freedom of Information Act request. In the letter, the agency said its investigation of the April 9 incident focused on whether United complied with the DOT’s oversales rule and federal anti-discrimination statutes.
