Dentons Autumn 2026 Aviation Update: TAP stake, Belgian block of NHV deal, EU passenger-rights overhaul
Why It MattersOwnership rules, foreign-investment screening and passenger-rights law are all tightening at once, so airline and helicopter deal outcomes now turn on regulators' security and control judgments as much as on price.
What happened
Dentons' Autumn 2026 Aviation Update covers aviation M&A, competition enforcement and regulation, alongside measures to "green" the sector. On consolidation, Lufthansa Group's offer for a 44.9% stake in TAP Air Portugal prevailed over a rival bid from KLM-Air France. Lufthansa could ultimately take up to 49.9%, and the deal is subject to regulatory approvals and European Commission scrutiny.
Belgium blocked the acquisition of helicopter operator NHV Group by Chinese-owned GD Helicopter Finance. It was the first prohibition under Belgium's foreign investment screening regime, which cited national-security and strategic risks that remedies could not address. Separately, Alaska Airlines is seeking to join American Airlines' immunised joint business arrangements.
On enforcement, the European Commission is considering changes to the rule that EU-licensed airlines be majority EU-owned and effectively controlled. A proposed GBP 5.7 billion acquisition of easyJet and Irish High Court proceedings over Ryanair's ownership structure have put those rules in focus. The Commission closed its antitrust investigation into Pratt & Whitney Canada after the company changed contracts governing its maintenance network, without finding its prior practices compliant. The US Court of Appeals for the Eleventh Circuit vacated the DoT's withdrawal of antitrust immunity for the D…
On regulation, the EU formally adopted its overhaul of air passenger rights. Compensation stays at EUR 250, EUR 400 and EUR 600 for arrivals more than three hours late, and rights are strengthened on rerouting, fare transparency, hand baggage and no-show policies. The regime applies from 23 October 2027. The European Commission is also reviewing its "Balanced Approach" rules on airport noise restrictions.
A NATS systems failure in September 2026 delayed, cancelled or diverted more than 2,000 UK flights. A further technical incident followed less than two weeks later.
Industry impact & what to watch
Three separate threads in this update point the same way: regulators are deciding airline and aviation-services deals on grounds beyond price. Belgium's NHV decision rested on national-security and strategic risk that no remedy could cure, which tells a bidder that certain buyer profiles can be excluded outright instead of being cleared with conditions. Lufthansa's TAP win is a different kind of test, since a 44.9% stake that can rise to 49.9% still has to pass European Commission scrutiny.
The ownership-and-control rule is the structural pressure point. With a GBP 5.7 billion easyJet bid and Irish High Court proceedings over Ryanair both putting it in focus, any Commission move to change the majority-EU-ownership requirement would alter who can legally buy European carriers. Until a proposal is published, deal structures still have to be built around the current rule.
Passenger-rights reform lands on a long runway: compensation tiers are unchanged, but stronger rerouting, fare-transparency and baggage provisions take effect only on 23 October 2027, leaving airlines time to adapt systems and policies. The next dated milestone is that application date, while the Commission's Balanced Approach review and any ownership-rule proposal remain the open items. The two NATS failures within two weeks add a resilience question for UK air-traffic systems that the update leaves unresolved.
