Airlines operating transatlantic routes between Europe and the United States have had a more solid and predictable regulatory framework since 2026. The subsidiary agreement published on 17 July 2026 in the EU Official Journal (reference OJ:L_202601745) consolidates the integration of Iceland and Norway into the common airspace already shared by the European Union and the US, thus completing a system of unified rules for transatlantic commercial aviation.
This agreement does not create new obligations from scratch: it complements and extends the main EU-US agreement to include the two Nordic countries, eliminating the legal uncertainty that existed regarding the status of Icelandic and Norwegian airline operations in this corridor.
What does this regulation establish?
The subsidiary agreement has as its main function to extend the umbrella of the air transport agreement between the EU and the US to Iceland and Norway, two countries that are not EU members but are part of the European Economic Area (EEA). The matters regulated under this unified framework are:
| Regulated matter | What it means for operators |
|---|---|
| Traffic rights | Clear framework on which routes airlines can operate between signatory territories |
| Competition | Harmonized rules to prevent anticompetitive practices on transatlantic routes |
| Air safety | Common standards mutually recognized among all signatory territories |
| Market access | Conditions for accessing routes between EU, US, Iceland and Norway under a single regime |
| Commercial agreements and codeshares | Harmonized framework that facilitates the signing of agreements between airlines of signatory territories |
Before this subsidiary agreement, the position of Iceland and Norway in the transatlantic airspace lacked the same legal certainty as the rest of the EU Member States. Its entry into force closes that gap and equates the status of operators such as Icelandair or Norse Atlantic Airways to that of European airlines with respect to this corridor.
Economic and operational impact
The impact of this agreement is mainly one of legal certainty and commercial opportunity, not immediate direct cost for operators. The concrete effects on business are:
- Greater legal certainty for European, Icelandic and Norwegian airlines when operating flights to and from the US, reducing the risk of regulatory disputes.
- Ease in closing codeshares between airlines of the different signatory territories, as they operate under a common and recognized regulatory framework.
- More predictable market access: airlines can plan routes and capacities with a longer time horizon without uncertainty about the applicable regime.
- Reduced barriers to entry for new operators wishing to launch transatlantic routes from or to Iceland and Norway.
- Indirect impact for Spanish airports with transatlantic connections, which may benefit from increased activity on routes with stops in Nordic territories.
This regulation does not establish new fees, tariffs or direct economic sanctions. The value for companies lies in the regulatory stability that allows them to make investment and expansion decisions with greater confidence.
Who does it affect?
- European airlines with transatlantic routes to the US or with codeshare agreements with Icelandic or Norwegian operators.
- Icelandic and Norwegian airlines that operate or plan to operate routes to the US or to the EU with transatlantic connection.
- Spanish and European airports with relevant transatlantic traffic (hubs and secondary airports with routes to the US).
- Tour operators that manage packages with flights on EU-US-Iceland-Norway routes.
- Travel agencies that market flights or packages on this transatlantic corridor.
- Legal and compliance departments of airlines that must update their regulatory analysis of international routes.
- Spain, as an EU Member State, is bound by this international agreement without need for additional ratification.
Practical example
A Spanish airline operating flights between Madrid and New York and maintaining a codeshare agreement with an Icelandic airline for routes with a stop in Reykjavik benefits directly from this agreement. Until now, the regulatory status of that codeshare on the Reykjavik-New York leg could raise legal doubts, since Iceland was not party to the main EU-US agreement with the same certainty as Member States.
With the subsidiary agreement in force, that codeshare operates under a single and harmonized regulatory framework that covers traffic rights, competition conditions and safety standards on all legs. The Spanish airline can negotiate and expand that commercial agreement with greater legal certainty and without needing to analyze different regulatory regimes for each leg of the route.
Similarly, a tour operator selling packages with flights Madrid-Reykjavik-Boston can structure its contracts with air suppliers with greater clarity on the regime applicable to each segment.
What should companies do now?
- Review existing codeshare agreements with Icelandic or Norwegian airlines to identify whether they benefit from the new harmonized framework and whether any contractual clause needs updating.
- Update the regulatory analysis of transatlantic routes that include stops or connections in Iceland or Norway, incorporating this agreement as the applicable regulatory reference.
- Evaluate commercial opportunities arising from greater market access: new routes, interline agreements or expansion of codeshares with Nordic operators.
- Inform operations and legal departments about the entry into force of the agreement so they can incorporate it into their international regulatory compliance analysis.
- Consult the official source on EUR-Lex to verify the exact date of entry into force, which has not been specified in the publication of 17 July 2026.
- Travel agencies and tour operators: review contracts with air suppliers on routes that include legs with Icelandic or Norwegian airlines to ensure they reflect the new regulatory framework.
Frequently asked questions
When exactly does the EU-US-Iceland-Norway air agreement enter into force?
The official publication in the EU Official Journal is dated 17 July 2026 (reference OJ:L_202601745), but the exact date of entry into force has not been specified in that publication. To find out the specific date, you need to consult the official source directly on EUR-Lex.
What matters does the subsidiary air transport agreement regulate?
The agreement regulates traffic rights, competition rules, air safety standards and conditions for accessing routes between signatory territories: the European Union and its Member States, Iceland, Norway and the United States. It also establishes the framework for commercial agreements and codeshares between airlines of these territories.
Does this agreement affect Spanish airlines?
Yes. Spain, as an EU Member State, is directly bound by this international agreement. Spanish airlines with transatlantic routes or codeshare agreements with Icelandic or Norwegian operators now operate under a harmonized legal framework and with greater regulatory certainty.
What is the difference between the main agreement and the subsidiary agreement?
The main agreement regulates air transport between the EU and the US. The subsidiary agreement complements that framework to integrate Iceland and Norway, two countries that are not EU members but are part of the European Economic Area. Its function is to equate the status of Icelandic and Norwegian operators to that of European airlines in this transatlantic corridor.
Does this agreement entail new fees or costs for airlines?
No. The published regulation does not establish new fees, tariffs or direct economic sanctions. Its impact is one of legal certainty and commercial opportunity: a harmonized regulatory framework that facilitates the operation of routes and the signing of commercial agreements between airlines of signatory territories.
