As Boeing’s legal woes mount, the aviation giant has retained a number of Big Law firms to handle litigation and investigations. The company’s recent legal counsel include Perkins Coie, Kirkland & Ellis, McGuireWoods, Jones Day, Mayer Brown and Quinn Emanuel Urquhart & Sullivan, according to court records.

Recently, Boeing turned to Perkins Coie to handle a new class action lawsuit related to a door plug blowout on a 737 Max 9 flight last month.
