San Diego County Supervisors approved United Airlines' lease to return to McClellan-Palomar Airport on December 11, 2025, despite opposition from Carlsbad officials and residents concerned about noise pollution. UAL confirmed it plans to use Embraer 175 aircraft, the same type generating complaints related to American Airlines' recent return; legal threats remain. UAL closed at $106.84 on December 12, following a modest 1.43% drop.
