Brazilian routes offer strategic gains, but regulatory delays threaten projected returns.
LISBON
Lufthansa’s proposed acquisition of up to 49.9% of TAP Air Portugal could generate approximately €450 million in annual savings and additional revenue, according to corporate bond research firm Gimme Credit. However, regulatory approvals, operational restrictions and the challenges of integrating another European airline could delay the financial benefits until 2030.
Portugal selected the German aviation group over Air France-KLM in October, marking a significant step in the partial privatization of its national carrier. The transaction remains subject to final negotiations and competition clearance, with completion currently expected in 2028.
Lufthansa has offered €1.025 billion for a 44.9% stake. The amount could rise to approximately €1.2 billion if it acquires additional shares initially reserved for TAP employees and pays fees accumulating before completion.
The Portuguese government would retain 50.1% ownership and a majority of board seats, while Lufthansa would receive the right to appoint TAP’s chief executive.
This arrangement provides the German group with considerable operational influence without granting full ownership. It could also limit its ability to reorganize routes, reduce overlapping activities or implement group-wide efficiencies.
TAP’s strongest attraction lies in its connections with Brazil and Latin America. The Portuguese airline controls approximately 24% of seat capacity between Europe and Brazil, according to aviation data company OAG.
Combining its network with Lufthansa’s existing airlines would increase the group’s share of that market to approximately 36%, strengthening its position in transatlantic aviation.
Potential benefits include coordinated schedules, purchasing efficiencies, maintenance cooperation and improved cargo operations. TAP’s Airbus fleet could also offer technical advantages because Airbus aircraft already represent a substantial portion of Lufthansa’s operations.
Nevertheless, the anticipated €450 million in annual synergies remains an estimate rather than realized earnings.
Gimme Credit has warned that integrating TAP into Lufthansa’s transatlantic joint venture with United Airlines and Air Canada could take longer than management expects.
The experience of ITA Airways illustrates the difficulty. Lufthansa’s investment in the Italian carrier began in January 2025, but regulatory delays have complicated its participation in coordinated transatlantic operations.
Another obstacle is Lisbon Airport, where capacity constraints restrict expansion. A replacement airport is not expected to become operational before 2034, limiting opportunities to increase traffic through TAP’s principal hub.
Lufthansa has pledged to expand TAP’s fleet to 117 aircraft by 2035 and invest €500 million in Portugal. Those commitments will require sustained financial and operational coordination.
TAP’s recent performance adds uncertainty. Although the airline remained profitable in 2025, its net earnings fell to €4.1 million, and it reported losses of €99.2 million during the first half of 2026.
For Portugal, the agreement offers potential investment and continued participation in the airline’s governance. For Lufthansa, it creates an opportunity to strengthen a strategically important international network.
The unresolved question is whether the acquisition price can be justified by financial benefits that may take several years to materialize.
