Palma Airport is entering another major period of investment just as Mallorca is having one of its biggest debates yet about how much tourism the island can accommodate.
Â
The Spanish Government approved its new five-year airport investment plan, DORA III, on 15 September. Almost €13 billion will be invested across Aena’s Spanish airport network between 2027 and 2031, with more than €1 billion earmarked for the Balearic Islands. Palma will receive €621.6 million.
Â
At the same time, passenger numbers at Palma are forecast to continue rising, creating a familiar question for Mallorca: how do you manage tourism growth when the island’s main gateway is being prepared for more demand?
What Is Planned for Palma Airport?
The investment isn’t simply about making Palma Airport bigger. The programme includes improvements to the airfield, aircraft parking areas, runways and taxiways, as well as passenger boarding bridges, public areas, parking and security systems. The aim is to modernise the airport, improve passenger flows and ensure the infrastructure can deal with future demand.
Â
Palma handled around 33.8 million passengers in 2025, and the DORA III planning figures envisage around 35.7 million by 2031. That is an increase of almost two million passengers, although it is important to distinguish between a forecast for future traffic and an official decision to increase the airport’s legal capacity by two million passengers.
Â
The Spanish Government says airports covered by DORA III will remain within their existing approved capacity and environmental framework.
Why Is There Concern?
The timing is what makes the issue particularly interesting. If you have been keeping up to date with our news lately (or any news regarding the Balearics) you will be well aware of the anti-tourism movement. Also, the Balearic Government has been pursuing policies aimed at containing tourism growth, while the island is also dealing with concerns around housing, traffic, water and pressure on public infrastructure.
Â
The airport therefore sits at the centre of a much bigger debate. If more people can continue arriving by air, how much control does Mallorca actually have over the number of visitors it receives? That question is one reason the Balearic Islands have been pushing for greater involvement in decisions concerning their airports.
Who Should Have a Say?
A proposal for greater co-management of the Balearic airports was presented to the Spanish Congress earlier this year.
Â
The proposal would give the Balearic institutions a greater role in airport planning and decision-making, including assessing the impact of airport activity on the islands’ population, environment, mobility and natural resources.
Â
The proposal is now moving through the parliamentary process rather than being simply dismissed, with the Congress currently listing it as pending consideration by the Plenary.
Â
That makes the debate over Palma Airport about more than terminals, runways and passenger numbers.
Â
It is also about who gets to decide how Mallorca connects with the rest of the world, and how much tourism the island can realistically accommodate.

Two Different Priorities
For Aena and the Spanish Government, continued investment reflects the importance of Spain’s airports and the demand already passing through them. The Government says DORA III is designed to modernise infrastructure, improve passenger experience and prepare the network for future needs.
Â
For those focused on tourism containment, the concern is different. Better infrastructure may make it easier for the island to accommodate continued growth at a time when there is already a major discussion about whether Mallorca has reached its limits.
Â
Neither issue exists in isolation.
Â
Mallorca needs an airport capable of serving its residents, businesses and visitors. But the island is also increasingly asking how much growth is sustainable. With more than €600 million now committed to Palma for the next five years, and the debate over airport co-management continuing in Madrid, Palma Airport is likely to remain at the centre of that conversation.
