Operators face strict parking limits for aircraft exceeding 20 meters, capped at seven days unless airport approval is secured. This constraint, detailed in OpsGroup’s Maps of Misery guide published 8 July 2026, forces adjustments to positioning strategies across European airports from June to October 2026. Fuel delays are now common at major hubs, with priority given to commercial outbound traffic. LFMT/Montpellier requires PPR for non-based business aviation, while LIPZ/Venice mandates PPR and limits ground time to 24 hours from mid-May to late October. Nice operates under tight slot tolerances, risking loss of parking if schedules change. Crews must maintain current EOBT and align flight plan times with confirmed slots. NOTAM checks for LPV restrictions remain essential, as availability shifts weekly. Verification of specific airport rules is mandatory, as no approved list for extended stays exists.
