European, Icelandic and Norwegian airlines operating flights to or from the United States have had, since August 2, 2026, a more solid legal framework under which to operate. The subsidiary agreement published in the BOE on July 17, 2026 ends the provisional application period that began with the signing of the agreement in 2011 and converts into full law what until now was a transitional regime.
This is not a regulation that introduces new operational obligations all at once: its relevance is legal and strategic. For executives and legal advisors in the aviation sector, the key is that the regulatory framework governing traffic rights and operating conditions on transatlantic routes is now fully consolidated, with all the guarantees that implies in terms of litigation, planning and negotiation of slots and routes.
What does this regulation establish?
The agreement regulates the legal framework for air transport between the European Union, Iceland, Norway and the United States. Its main content covers:
- Traffic rights: conditions under which airlines from each party can operate routes between the territories involved.
- Operating conditions: rules applicable to airlines regarding market access, tariffs and competition.
- Joint application framework: integrates Iceland and Norway—countries of the European Economic Area but not EU members—into the same regime as EU Member States.
The agreement was signed in two locations: Luxembourg on June 16, 2011 and Oslo on June 21, 2011. Since that date, Spain and the other parties have been applying it provisionally. Spanish ratification took place in May 2013. The formal entry into force on August 2, 2026 definitively closes that provisional period for all signatory States.
| Aspect | Situation until August 2, 2026 | Situation from August 2, 2026 |
|---|---|---|
| Legal regime | Provisional application since 2011 | Full legal force for all signatory States |
| Legal certainty | Transitional framework, with possible uncertainty in litigation | Consolidated framework, greater certainty in disputes and negotiations |
| Traffic rights | Provisionally recognized | Fully guaranteed under international law |
| Operational impact for Spain | Limited (ratification in May 2013) | Limited, with no additional immediate operational changes |
Economic and operational impact
The direct economic impact of this entry into force is low in the short term for most operators, especially Spanish ones, who have already been operating under the provisional regime since 2013. There are no new fees, new licensing requirements or changes in tariff conditions derived exclusively from this formalization.
However, there are relevant operational and strategic consequences for the legal and operations departments of airlines:
- Greater strength in legal disputes: any litigation related to traffic rights or operating conditions on transatlantic routes will now be resolved under a full legal framework, not a provisional one.
- Long-term planning: the consolidation of the agreement facilitates decision-making on route investment, fleet and strategic alliances with airlines from the USA, Iceland and Norway.
- Negotiation of slots and commercial agreements: the fully effective framework strengthens the negotiating position of European airlines against their US counterparts.
- Sector regulators: the civil aviation authorities of the signatory States now have a higher-ranking legal instrument to apply and enforce the conditions of the agreement.
Who does it affect?
- European airlines operating transatlantic routes to or from the USA (including Spanish airlines with flights to North American destinations).
- Icelandic airlines (mainly Icelandair and charter operators) with routes to the USA.
- Norwegian airlines with transatlantic operations.
- US airlines operating routes to the EU, Iceland or Norway.
- Regulators and civil aviation authorities of the signatory States.
- Legal and compliance departments of aeronautical groups with transatlantic operations.
- Legal advisors specialized in international aviation law.
Practical example
A Spanish airline operating direct flights between Madrid and New York has been doing so for years under the provisional regime of the agreement. Until August 2, 2026, if a dispute arose with US authorities over market access conditions or tariffs, the applicable legal framework was that of provisional application, which could generate uncertainty about the enforceability of certain rights.
From August 2, 2026, that same airline operates under an agreement in full force under international law. If the company wants to expand frequencies, negotiate a code-share agreement with a US airline or defend its traffic rights before a regulatory authority, it does so with the backing of an international treaty in full force, not a transitional regime. The difference is not operational in day-to-day operations, but it is relevant in scenarios of litigation, regulatory audit or strategic negotiation.
What should companies do now?
- Review current contracts and commercial agreements that reference the provisional regime of the 2011 agreement, to update the legal references to the new status of full force from August 2, 2026.
- Inform legal and compliance departments of the change in legal status of the agreement, especially if the company has active litigation or regulatory proceedings related to transatlantic routes.
- Take advantage of the consolidated framework for strategic planning: the full force of the agreement is an additional argument to drive investment decisions on routes, fleet or alliances with operators from the USA, Iceland or Norway.
- Consult with advisors specialized in international aviation law if the company has operations or disputes that may be affected by the change in legal regime.
- Monitor possible regulatory developments resulting from the full force of the agreement, both at European level and in the signatory States, which may translate into new operational obligations or rights.
Frequently asked questions
When does the air transport agreement between the EU, Iceland, Norway and the USA enter into force?
The subsidiary agreement enters into full legal force on August 2, 2026 for all signatory States. It was published in the BOE on July 17, 2026. The original agreement was signed in Luxembourg on June 16, 2011 and in Oslo on June 21, 2011, and has been provisionally applied since then.
What changes for Spanish airlines from August 2, 2026?
For Spain, the immediate operational impact is limited, since Spanish ratification took place in May 2013 and airlines have been operating under the provisional regime for years. The main change is legal: the framework governing traffic rights and operating conditions on transatlantic routes moves from being provisional to having full force, which strengthens legal certainty in disputes, negotiations and strategic planning.
Which airlines and operators does this agreement affect?
It directly affects European, Icelandic and Norwegian airlines operating flights to or from the USA, as well as US airlines with routes to the EU, Iceland or Norway. It also affects sector regulators (civil aviation authorities) and legal departments of aeronautical groups with transatlantic operations.
What is the difference between provisional application and full force of the agreement?
During provisional application (since 2011), the agreement was applied de facto but without the full legal backing of an international treaty in force. From August 2, 2026, the agreement has full legal force, which implies greater certainty in dispute resolution, greater strength in negotiating traffic rights and a more robust framework for regulators to enforce its conditions.
Are there new fees, requirements or sanctions resulting from this entry into force?
No. The entry into force on August 2, 2026 does not introduce new fees, licensing requirements or additional sanctions. Its effect is primarily legal: it consolidates and gives full force to the regulatory framework that has already been provisionally applied since 2011.
