The General Court’s ruling in American Airlines, Inc. v Commission has three distinct meanings. At one level, it is a narrow ruling on an airline industry-specific (and a largely standardised) access/divestment remedy for problematic airline-airline mergers subject to the EU Merger Regulation (Council Regulation No 139/2004 ‘EUMR’) (and, arguably, more widely for airline alliances subject to Article 101 investigation through the procedures in Regulation 1/2003 Regulation 1/2003). At another level, the ruling is relevant both to the substantive assessment of a prospective remedy and the manner in which merging parties communicate with the European Commission during the EUMR procedure
