Bucharest Henri Coandă Airport Moves to Full Level 3 Coordination

Romania’s busiest air gateway, Bucharest Henri Coandă International Airport, is set to become the country’s first fully slot coordinated airport as it transitions to Level 3 coordination under a new multi-year agreement with Airport Coordination Limited.

ACL Partnership Marks a Strategic Step for Romania’s Main Hub

Publicly available information shows that Bucharest’s Henri Coandă International Airport has signed a multi-year agreement with Airport Coordination Limited, the world’s largest independent airport slot coordinator. The move will see ACL take over full Level 3 slot coordination for arrivals and departures from the start of the 2026 to 2027 winter season, scheduled to begin on 25 October 2026.

According to published coverage, Henri Coandă will be ACL’s 80th coordinated airport worldwide and its latest client in Central and Eastern Europe. The British-based coordinator already manages slots at a range of major European hubs and regional gateways, and the Bucharest contract is being presented as part of its ongoing international expansion.

The National Company Bucharest Airports, which manages Henri Coandă, has framed the agreement as a step that aligns Romania’s primary gateway with operational practices in many of Europe’s busiest airports. Reports indicate that the change reflects not only the airport’s rapid passenger growth in recent years but also the increasing pressure on peak-hour capacity.

Henri Coandă handled more than 17 million passengers and around 127,700 aircraft movements in 2025, according to figures cited in local and international aviation outlets. Those volumes place the airport among the faster-growing airports in Central and Eastern Europe and underpin the decision to introduce formal slot coordination.

What Level 3 Coordination Means for Airlines and Schedules

Level 3 coordination is the strictest category in the internationally recognised airport capacity management system. Under this regime, every commercial airline wishing to operate at Henri Coandă will be required to obtain slots in advance, with allocations managed by ACL in line with European Union Regulation 95/93 and the Worldwide Airport Slot Guidelines developed by IATA.

In practical terms, an airport slot is a fixed take-off or landing time that must be requested and confirmed before an airline can schedule a flight. For airlines serving Bucharest, the transition means that access to popular early morning and evening peaks will be subject to more formalised planning and historical precedence rules, rather than largely ad hoc scheduling.

Industry reports suggest that coordination will make it easier to match runway, terminal and airside capacity to real demand across the day. By smoothing out bottlenecks at the busiest hours, the airport and its partners aim to reduce delays, improve on-time performance and make better use of existing infrastructure.

For passengers, the change is expected to be largely invisible in day-to-day travel planning. However, observers note that more predictable slots may translate into more reliable departure and arrival times, especially during the congested early morning banks of flights and at the end of the day when delays tend to accumulate.

Growing Traffic and Capacity Pressures Behind the Shift

The decision to move Henri Coandă to full Level 3 coordination follows several years of steady growth in traffic and a broader programme of upgrades at the airport. Published data show that traffic has climbed significantly since the pandemic, driven by both low-cost and full-service carriers expanding their networks from Bucharest.

Romania’s entry into the Schengen Area for air travel has also influenced traffic patterns, as flows within the European Union have become more seamless. Together with rising inbound tourism and outbound demand from Romanian travellers, this has placed greater strain on terminal and runway capacity at peak times.

At the same time, the airport operator has been working on modernisation projects such as upgrading passenger flows, replacing moving walkways and escalators, and reorganising access for ground transport. These initiatives aim to ease congestion and bring facilities in line with the level of activity now seen at the country’s main hub.

According to aviation analysts cited in trade publications, the introduction of Level 3 coordination can be viewed as part of that broader transformation, shifting Henri Coandă from a primarily schedule-facilitated airport to one that follows the coordination standards used at Europe’s largest and most densely used hubs.

Implications for Romania’s Aviation Market and Network Growth

The move to full coordination at Henri Coandă is expected to have ripple effects across Romania’s aviation landscape. With access to Bucharest’s main international gateway now governed by formal slot rules, airlines may reassess their growth strategies, balancing expansion in the capital with opportunities at secondary airports.

Industry commentary points to growing roles for other Romanian airports, including regional gateways that can absorb additional capacity from carriers looking to expand without the constraints of a fully coordinated hub. This could support a more distributed air network within the country as demand continues to rise.

For Bucharest itself, Level 3 coordination may help secure the airport’s position as a competitive connecting point in the region. By managing congestion and maintaining punctuality, the airport aims to remain attractive for both point-to-point and transfer traffic, including new long-haul or high-frequency short-haul services that require reliable access to peak periods.

Aviation observers note that the agreement with ACL also sends a signal to the wider market that Henri Coandă is entering what some describe as the “big league” of European airports. Coordination is widely considered a hallmark of airports where demand consistently approaches or exceeds declared capacity, requiring independent management of scarce slots.

Timeline and Next Steps Before Winter 2026

The transition to full Level 3 coordination will not take effect immediately. Reports indicate that ACL’s mandate at Henri Coandă will formally begin with the start of the 2026 to 2027 winter season on 25 October 2026, providing more than a year for preparation and system alignment.

During this period, ACL and the airport operator are expected to work within established international procedures to declare capacity, prepare initial slot parameters and inform airlines of the new coordination status. Carriers will then need to request and confirm their slots as part of the regular seasonal scheduling process leading into winter 2026.

Observers highlight that the runway to implementation will be closely watched by airlines and regulators alike, as it will set the framework for how Bucharest manages growth in the second half of the decade. Given Henri Coandă’s role as Romania’s primary gateway, the success of the transition is likely to influence future infrastructure and policy decisions in the country’s aviation sector.

As the start date approaches, industry updates are expected to provide further detail on capacity declarations, coordination parameters and how the new slot regime will interact with ongoing investment and operational changes at the airport.
