New ICAO security standards 2026: what changes for airlines and airports

Key data

European airlines and airport managers operating international flights face a mandatory update of their security protocols. The Council Decision (EU) 2026/1369, adopted on 12 June 2026, establishes the common position that EU Member States must defend at the 238th session of the ICAO Council, where Amendment 19 to Annex 17 of the Chicago Convention will be voted on.

Annex 17 is the international standard that regulates civil aviation security against acts of unlawful interference—sabotage, hijackings, terrorist threats—and its update involves reviewing operational procedures at airports and on board aircraft.

What does this regulation establish?

The EU Council Decision does not directly adopt the amendment: what it does is coordinate the European vote in the international ICAO forum. All Member States must vote in alignment following this common position, which strengthens the EU's negotiating weight in international aviation bodies.

The subject of the vote is Amendment 19 to Annex 17 of the Convention on International Civil Aviation (Chicago Convention), which updates international standards on:

• Airport security against acts of unlawful interference
• Security on board aircraft in international operations
• Protocols for control and verification of passengers, baggage and goods

Once the amendment is adopted within ICAO, Member States and operators under their jurisdiction will be obliged to adapt their systems and procedures to the new international standards.

Economic and operational impact

The direct impact of this decision is operational and regulatory compliance. The regulation does not set sanctions or specific amounts, but updating ICAO standards typically involves reviews in:

• Security control systems in airport terminals (detection equipment, inspection procedures).
• Training of security personnel at airports and airlines to adapt to new protocols.
• Documentation and compliance certifications that civil aviation authorities will require from operators.
• Coordination with national civil aviation authorities, which will be responsible for translating the new ICAO standards into the domestic regulatory framework.

The harmonisation of the European vote also has a strategic consequence: by presenting itself as a unified bloc at ICAO, the EU increases its capacity to influence the final drafting of standards, which can result in regulations more aligned with practices already in force in Europe and, therefore, in lower adaptation costs for European operators.

Who does it affect?

• Airlines with international operations: must review and update their operational security manuals in accordance with the new Annex 17 standards.
• Airport managers: will have to adapt airport security programmes to the requirements of Amendment 19.
• Civil aviation authorities (in Spain, AESA — State Agency for Air Safety): responsible for transposing and supervising compliance with new ICAO standards at national level.
• International flight operators: any company operating routes with origin or destination outside the EU and which must comply with the Chicago Convention standards.
• Airport security service providers: companies providing passenger, baggage and goods control services at international airports.

Practical example

A Spanish airline operating regular flights between Madrid and destinations outside the EU is subject to the Chicago Convention and, therefore, to Annex 17 standards. Once ICAO formally adopts Amendment 19 at the 238th session of the Council, AESA will communicate to national operators the specific changes they must incorporate into their security programmes.

In practice, this may mean that the airline must update its Company Security Manual, retrain its cabin and ground personnel in the new procedures, and undergo a compliance audit by the competent authority. The timeframe for this adaptation will be set by ICAO itself when publishing the amendment, and AESA will transfer it to the Spanish regulatory framework.

What should companies do now?

1. Identify if your operation is subject to Annex 17 of the Chicago Convention: if you operate international flights or manage an airport with international traffic, the answer is yes.
2. Follow the progress of the 238th session of the ICAO Council: Amendment 19 still needs to be formally adopted. Monitor ICAO and AESA communications to learn the date of entry into force.
3. Contact the national civil aviation authority (AESA in Spain): request information on how the new standards will be transferred to the domestic regulatory framework and what adaptation timelines will be established.
4. Review current security programmes: identify areas of operational manuals and security protocols that may be affected by an update to Annex 17.
5. Plan staff training: anticipate the need to update security training for ground, cabin and access control personnel, to avoid delays when the amendment enters into force.
