Tallinn Airport signs €66.6m terminal contract as traffic exceeds design capacity

Tallinn Airport has signed a €66.6 million passenger-terminal expansion contract with a consortium of Tallinna Ehitustrust and Ehitustrust, moving one of Estonia’s largest aviation infrastructure projects into a 31-month construction programme.

The investment is being driven by an increasingly visible capacity mismatch. Tallinn Airport says its existing terminal was designed for approximately 2.8 million passengers annually but is already serving close to 3.8 million, meaning current throughput is roughly 36% above the original design level.

The expansion is intended to lift future capacity to five million passengers a year while improving baggage reclaim, border control, boarding gates, retail and food-and-beverage areas. About 16,500 square metres of new terminal space will be added between 2025 and 2029, alongside renovation of approximately 18,000 square metres of the existing building.

Preparatory work is scheduled to begin in autumn 2026, with major interior construction starting in early 2027. The airport will remain open throughout the programme, making construction sequencing and passenger-flow management nearly as important as the physical expansion itself.

How far above its original design capacity is Tallinn Airport already operating?

A terminal designed for 2.8 million passengers but processing nearly 3.8 million is handling approximately one million more travellers annually than its intended design level. That represents around 35.7% more passengers than the original capacity assumption.

Operating above design capacity does not mean an airport becomes unusable. It generally means peak periods create increasingly visible pressure around security, check-in, baggage reclaim, immigration, boarding gates and commercial areas.

Those constraints can worsen disproportionately as traffic rises because several flights can arrive or depart within the same short window. An airport may appear comfortable during much of the day while experiencing severe crowding at specific peaks.

Tallinn’s expansion therefore addresses service quality as well as future growth. More physical space gives the airport greater ability to absorb peak traffic without relying on operational workarounds that become progressively harder as passenger numbers increase.

What will the €66.6 million expansion physically add?

The project includes a new terminal section on the site of a car park between the existing passenger terminal and public-transport terminal. That section will contain a new baggage-reclaim area, additional baggage carousels, shops, restaurants and cafés.

Two new boarding gates will be created, while the adjacent aircraft parking and servicing apron will be expanded to support those gates. Border-control and gate areas will also be enlarged to improve handling of non-Schengen traffic.

The programme also renovates large parts of the existing terminal rather than simply attaching a new wing. Roughly 18,000 square metres of existing space are due for refurbishment in addition to the 16,500 square metres of new space being created.

That balance matters because older passenger flows and systems can remain bottlenecks even after additional floor area is built. Renovating the existing terminal allows Tallinn Airport to change how passengers move through the whole building rather than treating the extension as an isolated facility.

Why is building inside an operating airport more difficult than a greenfield terminal?

Tallinn Airport cannot simply close the existing terminal for 31 months while contractors work. Passengers, airlines, baggage systems, security operations and air traffic must continue functioning throughout construction.

That requires the project to be divided into stages so that each area can be taken out of service temporarily without disabling the wider airport. Temporary passenger routes, construction barriers and changing access points can create operational complexity even before the first major structural challenge appears.

Construction work also needs to coexist with aviation security requirements. Workers, vehicles, materials and equipment entering operational airport areas can require additional access controls and scheduling that ordinary commercial construction does not face.

The airport has already warned passengers to expect temporary changes and some inconvenience. Project success will therefore be measured partly by whether Tallinn can maintain normal flight operations while rebuilding substantial portions of the terminal around them.

Why does the five-million-passenger target matter for Estonia’s connectivity?

Tallinn is Estonia’s primary international air gateway, making airport capacity directly relevant to tourism, business travel and connections with European commercial centres.

Increasing annual capacity toward five million creates room for roughly 1.2 million more passengers compared with the airport’s current near-3.8-million level. It does not guarantee that traffic will reach five million immediately, but it removes a physical constraint on airline growth.

Additional non-Schengen capacity can be particularly valuable as airlines add destinations outside the European passport-free travel area. Border-control infrastructure can otherwise become a limiting factor even when gates and runways have available capacity.

Commercial space adds another economic dimension. More passenger dwell time and additional shops or restaurants can increase non-aeronautical revenue, helping the airport earn income beyond airline and passenger charges.

Is €66.6 million the complete cost of Tallinn Airport’s transformation?

The €66.6 million figure relates to the newly signed construction contract for the passenger-terminal expansion works. Tallinn Airport has described the broader renovation as a multi-year programme extending from 2025 to 2029, meaning other investments can sit outside the main construction contract.

The airport has already undertaken improvements to check-in areas, self-service kiosks and bag-drop systems. Those completed or parallel upgrades form part of the broader transformation but should not automatically be treated as included inside the €66.6 million construction value unless specifically identified.

Investors and construction-industry observers should therefore distinguish the main terminal contract from total airport capital expenditure during the expansion period.

The next useful cost indicators will come as individual systems, fit-out and airside works progress and the airport updates its overall investment programme.

What are the biggest execution risks over the next 31 months?

Schedule discipline is crucial because prolonged construction can increase passenger disruption and push costs higher. Working around operational constraints can also create surprises that are less common on an empty greenfield site.

Traffic growth itself creates another challenge. If passenger numbers continue increasing while construction removes parts of the terminal temporarily, the airport could face its tightest capacity conditions precisely while the expansion is underway.

The contractors also need to integrate new baggage, gate and border-control infrastructure with existing systems without creating unreliable interfaces.

Tallinn Airport nevertheless enters the programme with a clear demand rationale. It is not building for a theoretical future passenger surge alone; it is expanding a terminal already operating well beyond its original 2.8-million-passenger design capacity.
