Their opening marks the first phase of a partnership between Lagardère Travel Retail and the airport to operate more than 600sqm of retail and F&B outlets at the African gateway.
The Aelia Duty Free store offers a broad range of local brands and products in addition to the wide range of international brands.
"We are very pleased with these openings, that demonstrate our ability to bring the best international operational standards to Africa, while developing a very strong and successful local offer," enthuses Lagardère Travel Retail's managing director for Africa, Bruno Bouchacourt.
"This is yet another important milestone in Lagardère Travel Retail's journey towards new successes in Africa."
Libreville Leon Mba International Airport is the only international airport in Gabon and, as such, a key location for air traffic in Western Africa and Europe.
It is currently served by 14 scheduled airlines that between them fly to 23 destinations in 15 countries.
The airport is set to be replaced by the New Libreville international Airport in 2021, which is expected to transform air travel to the Gabon.
Located on a 12 square kilomete site 50km to the north of the existing gateway, the new airport will initially be capable of handling 2.5 million passengers per annum, although plans are already in place to double this to 5mppa if demand dictates.
