Ibiza's airport reform has become the centre of an increasingly heated debate, with warnings ranging from more flights and tourists to greater pressure on housing, roads, water and public services.

Some of those concerns relate to genuine questions about the scale of the planned infrastructure. Others, however, go beyond what the available project documentation actually establishes.

With a demonstration against the airport project scheduled for Sunday, September 20, the distinction between what Aena has formally proposed, what opponents predict could happen and what remains speculation has become increasingly important.

The airport project is a major physical intervention

Aena's planned Ibiza Airport remodelling is part of the DORA III investment programme for 2027-2031.

The announced investment for Ibiza is €229.7 million.

The project includes a substantial reconfiguration of the terminal, including an increase from the current 17 boarding gates to 32, 16 additional check-in counters, a new approximately 170-metre passenger pier and eight new boarding bridges.

Aena also plans new security equipment, improvements to passenger facilities, additional office space, a passenger terrace and a larger VIP lounge.

So while the final construction project has not yet been drafted, it is accurate to describe the planned intervention as substantial.

Aena says it is not increasing hourly aircraft capacity

One of the most important distinctions in the debate concerns airport capacity.

Aena has said that the remodelling will not increase the number of aircraft take-offs and landings that Ibiza Airport can handle per hour.

The airport operator's explanation is that the additional gates and new passenger areas are needed partly because Schengen and non-Schengen passengers must be processed separately.

Aena specifically says that more gates are necessary even with the same level of traffic because they cannot be used as flexibly between the two passenger flows.

The company therefore distinguishes between the capacity of the terminal to process and distribute passengers and the operational capacity of the airfield itself.

Why there are still concerns about more passengers

Opponents of the project argue that a substantially larger terminal could nevertheless facilitate higher passenger volumes in the future.

GEN-GOB, for example, has argued that the planned intervention could lead to a much larger volume of airport traffic and contribute to further tourism pressure.

That is an environmental organisation's projection about the consequences of the project, not a figure established by Aena's current project documentation.

The technical documentation does not state that Ibiza Airport will double its passenger traffic as a result of the works.

Ibiza already handled more than nine million passengers

The debate is also taking place against a backdrop of record-level airport use.

Ibiza Airport handled 9,138,224 passengers in 2025, according to Aena.

The figure included 5,345,383 international passengers and 3,774,781 domestic passengers. The airport recorded 85,086 aircraft operations during the year.

These are passenger movements through the airport, not a count of unique tourists visiting Ibiza.

That distinction is important when discussing claims about the number of visitors the island could receive.

There is no confirmed “doubling of tourists”

The phrase “double the tourists” has appeared in the wider public debate, but it should not be reported as an established consequence of the airport project.

The current documentation does not say that Ibiza will receive twice as many tourists after the remodelling.

Passenger numbers are affected by airline schedules, demand, aircraft movements, seasonality and other factors.

A larger or more efficient terminal can influence how passengers are processed, but that does not automatically translate into a specific number of additional tourists.

The claim that the project itself will double tourism therefore remains a prediction rather than a confirmed outcome.

The alleged airport macrodiscotheque

Another claim circulating around the controversy concerns a possible large nightclub inside the airport.

This is not included in Aena's published project description.

The current technical material includes additional commercial and restaurant space and a new VIP lounge, but there is no confirmed macrodiscotheque in the project.

The Association of Nightlife Businesses Noches de Ibiza has publicly asked Aena to clarify whether such a project exists.

That request should not be confused with confirmation that a nightclub is planned.

Aena has denied that the airport project includes a discotheque.

More commercial space is actually planned

There is, however, a real commercial component to the remodelling.

Aena's plans include renewed commercial areas and support spaces as part of the terminal reconfiguration.

The new VIP lounge is also part of the project.

Those elements are documented.

Turning them into a claim that Ibiza Airport will contain a new macrodiscotheque goes beyond the available evidence.

The physical expansion goes beyond the gates

The project is not limited to changing the interior layout.

The technical documentation includes an extension of the terminal building, with the southwest façade moved approximately 60 metres and the airside façade advanced by around 24 metres.

A new northeast pier is planned at approximately 170 metres long and 24 metres wide.

The documentation also includes a new aircraft-support area, around 9,400 square metres of platform for handling equipment, approximately 8,000 square metres for parking and access, and a building for aeronautical activities and workshops of around 7,000 square metres per floor.

The project also foresees diverting approximately 700 metres of the Camí des Codols and burying at least 200 metres of the Torrent de sa Font, subject to environmental processing.

So it would be inaccurate to describe the proposal as merely cosmetic refurbishment.

More boarding bridges are planned

The number of boarding bridges is another genuine change.

Aena currently says around 25% of flights during the high season are served through this type of direct boarding connection.

After the remodelling, that proportion could rise to around 75%.

This is presented by Aena as an improvement in passenger comfort and operational efficiency, rather than an increase in the number of aircraft movements per hour.

The Schengen changes are a major reason for the redesign

Aena says European border-control requirements are one of the main reasons for the new configuration.

The current arrangement does not allow the existing boarding gates to continue handling Schengen and non-Schengen passengers in the same way indefinitely.

The project therefore includes a new dedicated non-Schengen pier and centralised passport-control arrangements.

Aena says the separation is necessary to comply with European requirements and to improve passenger processing.

This is one of the documented reasons for the additional gates.

The final construction project has not yet been drafted

This is another important point that should remain in any accurate report.

The current project is based on a functional design.

The final construction project has not yet been drafted, and the works themselves have not yet been tendered.

That means some technical details can still change as the project moves through later stages.

Consequently, figures or interpretations presented as the definitive final airport configuration should be treated cautiously at this stage.

What the environmental groups are warning about

GEN-GOB and other groups opposing the project are not simply disputing the need to repair or modernise airport facilities.

Their broader argument is that additional infrastructure could facilitate continued growth in tourism and increase pressure on Ibiza's already limited resources.

They have linked the airport debate to housing, road congestion, water consumption, waste, healthcare and the protection of natural areas.

These are policy and environmental arguments about the potential consequences of airport growth. They should be attributed to the organisations making them rather than presented as established consequences of the project.

The political debate is also about capacity

The airport issue has moved into the political arena.

The PSOE's Ibiza federation has said it supports an airport that is safer, more accessible, efficient and sustainable but rejects measures that increase operational capacity and therefore encourage more air traffic and passengers.

A June parliamentary initiative also called for rejection of airport reforms that would increase airport capacity and passenger flows.

The parliamentary document described the €229.7 million DORA III investment and argued that the proposed changes would increase airport infrastructure and support higher traffic.

That document represents the position and arguments contained in the parliamentary initiative. It does not establish the future number of passengers Ibiza Airport will actually handle.

The Balearic Government says its position was different

The Balearic Government has also entered the dispute.

On September 18, it published a statement saying it had explicitly told Aena in a May 6 letter that DORA III investments should not be linked to increases in passenger numbers.

The Government said its requests focused on issues including ground mobility, intermodality, sustainability, climate adaptation, passenger comfort and winter connectivity, and that none of its requests were linked to increasing the operational capacity of the islands' airports.

The Government has therefore rejected the interpretation that its own proposals sought airport capacity expansion.

This is a disputed political and institutional issue, so the positions of the different administrations should be kept clearly attributed.

Workers have a different set of concerns

Airport workers have also raised concerns, but their focus is not identical to that of environmental campaigners.

The airport's centre committee has raised questions about staffing, parking and the condition of existing facilities.

Workers have reportedly described difficulties finding parking during peak periods, with some saying they arrive substantially earlier than their shifts to secure a space.

They have also raised concerns about toilets, maintenance and the workload associated with existing facilities.

These issues concern the airport as it operates today rather than proving what the future project will ultimately deliver.

What is confirmed, and what is not

The current evidence allows several points to be separated clearly.

Confirmed:

• Aena has planned €229.7 million of investment for Ibiza Airport for 2027-2031.

• The number of boarding gates is planned to rise from 17 to 32.

• Eight new boarding bridges are planned.

• A new non-Schengen pier is planned.

• The terminal building itself will be physically reconfigured and extended.

• New commercial, restaurant and passenger facilities are included.

• Aena says hourly aircraft-movement capacity will not increase.

• The final construction project has not yet been drafted.

Not established:

• That passenger numbers will double.

• That tourist arrivals will double because of the project.

• That the airport will contain a macrodiscotheque.

• That the project will automatically produce more illegal tourist apartments.

• That the reform will inevitably lead to a particular number of additional flights.

Those latter points are predictions, concerns or claims made by different groups, rather than confirmed features or outcomes of the current project.

Why the distinction matters

The airport debate is ultimately about more than a building.

Ibiza is already dealing with record-level passenger movements, pressure on housing and infrastructure, and a long-running debate about the island's tourism limits.

That makes concerns about future airport growth politically and socially significant.

At the same time, accurately describing the current project requires distinguishing between a larger terminal, greater passenger-processing infrastructure and an increase in the airport's operational aircraft capacity.

The current evidence supports the first two. Aena explicitly says the third is not part of the project.

The final construction project has not yet been drafted, meaning the debate is likely to continue as more technical details become available.
