EU-Switzerland Air Agreement 2026: what changes for airlines and what they must review

Key data

European and Swiss airlines operating routes between both territories have an immediate obligation: to review their operational procedures in light of the new annex to the EU-Switzerland bilateral aviation agreement, in force since June 15, 2026. Decision No. 1/2026 of the Air Transport Joint Committee, published in the Official Journal of the EU on June 18, 2026 with reference [2026/1252], completely replaces the previous annex and incorporates the updated EU acquis in aviation matters.

This is not a minor wording change. The replacement of the annex means that the regulatory framework under which these airlines operate is renewed in full, affecting four critical areas of the air business.

What does this regulation establish?

The bilateral aviation agreement between the European Community and the Swiss Confederation is the legal instrument that allows airlines from both parties to operate in an integrated air market, similar to the European single airspace. This agreement is updated periodically to reflect the evolution of the EU acquis in aviation.

Decision No. 1/2026 replaces the complete annex to the agreement. That annex is the key technical piece: it sets out which European regulation applies to air operations between the EU and Switzerland. By replacing it, all regulatory updates from the EU that had occurred since the last review are incorporated.

The four regulatory areas affected by the new annex are:

The central objective of the decision is to ensure that Switzerland remains aligned with the EU acquis in aviation, ensuring regulatory homogeneity between European and Swiss airlines and the continuity of the integrated air market.

Economic and operational impact

The main impact is not direct immediate cost, but operational risk from non-compliance. An airline that does not adapt its procedures to the new framework may find itself operating outside the required regulatory standard, with consequences for its licenses and traffic rights.

The specific operational effects that airlines must anticipate are:

• License review: Compliance departments must verify that existing operating licenses meet the requirements of the new annex.
• Operations manual updates: Operational safety procedures must reflect the new European standards incorporated.
• Traffic rights verification: Routes operated between the EU and Switzerland must be covered by traffic rights compliant with the new framework.
• Commercial agreements review: Agreements between airlines (codeshares, interlines) must be compatible with updated competition rules.

The retroactive entry into force on June 15, 2026 — three days before official publication — means that the adaptation period is practically non-existent. Airlines must act immediately.

Who does it affect?

• European airlines operating regular or charter routes to or from Switzerland.
• Swiss airlines (in particular Swiss International Air Lines and other operators based in Switzerland) operating to any EU Member State.
• Compliance and operations departments of these airlines, responsible for verifying compliance with the new annex.
• Legal advisors and aviation consultants providing services to air operators in the EU-Switzerland market.
• National civil aviation authorities of Member States, which must apply the updated framework in their supervisory functions.

Practical example

A Spanish low-cost airline operates three daily routes between Spanish airports and Zurich. With the entry into force of the new annex on June 15, 2026, its compliance department must:

1. Verify that its operating licenses for routes to Switzerland remain valid under the new regulatory framework incorporated into the annex.
2. Review that its operational safety procedures are aligned with the updated European standards now required in the bilateral market.
3. Check that the traffic rights supporting those three daily routes comply with the new annex.
4. Audit any codeshare or interline agreement with Swiss airlines to ensure compatibility with updated competition rules.

If it does not conduct this review and operates without complying with any of the new requirements, it risks civil aviation authorities — Spanish or Swiss — detecting non-compliance during an inspection, with the risk of suspension or restriction of its operational rights on those routes.

What should companies do now?

1. Access the text of the new annex: Download and review the complete content of the replaced annex published in the Official Journal of the EU (reference OJ:L_202601252) to identify which specific European regulation is incorporated.
2. Audit operating licenses: Verify that all licenses to operate EU-Switzerland routes comply with the requirements of the new regulatory framework.
3. Review operational safety manuals: Update internal procedures to reflect the new European standards required from June 15, 2026.
4. Check existing traffic rights: Confirm with the legal department that the traffic rights supporting each operated route comply with the new annex.
5. Review commercial agreements with Swiss airlines: Audit codeshares, interlines and other agreements to ensure compatibility with updated competition rules.
6. Coordinate with the national civil aviation authority: Consult with the competent authority (in Spain, AESA) if there is any notification procedure or file update procedure resulting from the new annex.
