The battle for the Portuguese flag carrier has entered its decisive phase with strategic proposals from two of Europe’s largest airline groups, both vying to dominate the Lisbon hub and the strategic South Atlantic market.
Strategic Privatization and Regulatory Context
The Portuguese government formally relaunched the privatization process for Transportes Aéreos Portugueses (TAP) in July 2025, aiming to sell a minority 44.9% stake to an airline industry strategic partner capable of boosting the carrier’s competitiveness and global reach.
The Portuguese Executive has warned that TAP needs to be integrated into a larger-scale aviation group. According to authorities, European Union state aid rules prevent further public funding from being allocated to the airline, leaving it vulnerable to potential disruptions in the global aviation market.
Following the submission of non-binding offers last April, Air France-KLM and Lufthansa Group emerged as the sole two contenders in the race. Both proposals were preliminarily described by the government as “broadly equivalent and highly ambitious” across industrial, financial, and strategic dimensions.
Competitive Bids: Two Visions for the Lisbon Hub
While the exact figures of the binding offers have not been disclosed by either the government or the airlines, analysts at Bernstein estimate the value of the 44.9% stake in TAP at approximately €700 million, based on an enterprise valuation of €1.5 billion. Furthermore, official estimates from Lisbon indicate that European airline consolidations of this nature typically yield operational synergies and cost savings of around 7% of the acquired carrier’s revenue—which, in TAP’s case, would represent roughly €300 million annually.

Air France-KLM Proposal
Air France-KLM Chief Executive Officer Benjamin Smith stated that their binding bid extends beyond a financial figure, offering a long-term industrial plan backed by its North American partner Delta Air Lines to build a global aviation champion in Europe:
- Dedicated Hub: Transform Lisbon Airport into its sole hub in Southern Europe.
- Intercontinental Network: Enhance links to the Americas and Africa, leveraging TAP’s strong market presence in Brazil.
Lufthansa Group Proposal
Meanwhile, Lufthansa CEO Carsten Spohr characterized the interest in TAP—a fellow Star Alliance member—as the logical next step to reinforce the airline within its corporate structure and position Lisbon as a strategic hub in the South Atlantic:
- Scale and Financial Backing: As the largest airline group outside the United States, Lufthansa would provide scale, operational expertise, and financial stability.
- Brand Preservation: Spohr supported the bid by highlighting the group’s track record in developing national flag carriers—such as SWISS, Austrian Airlines, Brussels Airlines, and ITA Airways—while maintaining their distinct local identities.
Government Criteria and TAP’s Strategic Value
TAP’s most coveted asset lies in its highly valuable and lucrative slots (takeoff and landing rights) at Lisbon Airport, connecting the Portuguese capital with Brazil, Portuguese- and Spanish-speaking African nations, and the United States. These routes remain essential pillars for the overseas Portuguese diaspora, domestic tourism, and inward investment.
Portugal’s Minister of Infrastructure, Miguel Pinto Luz, emphasized that the contract award will not be determined solely by price. The government requires the selected partner to support aviation development across all Portuguese territory, strengthening connectivity and flight operations not only in Lisbon, but also at Porto, Faro, the Azores, and Madeira airports.
Next Steps
Following the formal receipt of binding bids from Air France-KLM and Lufthansa, the Portuguese government will begin a detailed evaluation of both strategic plans before awarding the 44.9% stake in TAP—a milestone set to reshape airline alliances across the South Atlantic.
