London Luton Airport (LLA) has become the first UK airport to achieve Level 4 accreditation under Airports Council International (ACI) Airport Customer Experience Accreditation programme, placing it among a small group of airports recognised for high standards in passenger service and operational performance.
Passenger experience drives accreditation
The Level 4 status recognises airports that demonstrate a long term commitment to improving customer experience through innovation, governance and operational efficiency.
The milestone follows a year of record customer satisfaction scores for the airport, with passengers praising improvements to processing times, staff support and transport connectivity. LLA had already become the first UK airport to secure Level 3 accreditation in 2025 before progressing to the next stage this year.
LLA Chief Operations Officer, Neil Thompson, said the achievement reflected the work carried out across the airport to improve journeys for passengers:
“Our approach is built on engagement, training and a commitment to continuous improvement, ensuring every team understands their role in shaping a seamless passenger journey.”
Airport officials said customer feedback over the past year highlighted the friendliness of staff, improved efficiency at security and check in as well as upgraded retail and dining facilities.
Third in Europe to reach Level 4
The accreditation also places LLA in a select European group as the only other airports in Europe holding this accreditation are iGA Istanbul Airport (IST) and Vienna International Airport (VIE).
The programme assesses airports on a wide range of criteria, including customer understanding, staff engagement, service innovation and collaboration across airport operations.
Director of ACI World, Justin Erbacci, congratulated the airport on the achievement, noting that customer experience remains central to the aviation sector’s future growth.
Accessibility and Investment a key focus
The recognition comes amid a wider investment in passenger services at the airport. In 2025, LLA received a “Very Good” rating in the UK Civil Aviation Authority’s accessibility assessment and introduced a new accessibility lounge for passengers requiring additional support.
The airport has also collected several industry awards over the past year, including recognition for customer-centric culture at the UK Customer Experience Awards.
The latest accreditation is expected to strengthen London Luton Airport’s position as it continues to expand passenger numbers and invest in services.
