March 6 (Reuters) - Airport operator Aena said on Thursday it expects more than 300 million passengers through its terminals in Spain during 2025, a year earlier than it had forecast in 2022.

Traffic at Spain's airports, which are all operated by Aena, rose 16% to a record 283.2 million passengers last year, 3% more than in 2019, as tourism rebounded after several years of disruption caused by the pandemic.

Aena's passenger numbers are recovering more rapidly than those of other airport operators in Europe, and it expects to manage around 1 million per day by 2026.

As a result, the company forecast robust growth, with a more than 20% surge in earnings before interest, tax, depreciation and amortisation (EBITDA) from 2023 to 2026.

The group, which also manages terminals in Latin America and Britain, expects 48% growth in its commercial revenue in 2026 compared to 2019 levels.

The anticipated passenger growth is in line with Aena's investment plan, which aims to double investments relative to recent years from 2027 to 2031.

That will include further expansion and enhancements to Aena's airport infrastructure, mainly in Spain.

Aena, which handles 20% of passenger traffic in Brazil, said international activity should make up 15% of its EBITDA in 2026, from 3.5% in 2019. (Reporting by Natalia Siniawski and Corina Rodriguez, editing by Joan Faus, Susan Fenton and Milla Nissi)
