The Royal Naval Air Station was built near Mahebourg at Plaine Magnien back in 1942. Used as a military-based during WW2. After the war, it became an operational civil airport and gave a boost to the economy. The flight to Rodrigues island was made on 10 September 1972, from Plaisance airport to the Plaine Corail Airport using an MK Twin Otter (3B-NAB). Later in 1986, a new terminal was built, consisted of 2 floors and airbridges which could accommodate up to four aircraft simultaneously.

A new passenger terminal was inaugurated on 30 August 2013 and became fully operational in September 2013. The structure of the New Airport Terminal is designed after the "Traveller's palm", a tropical plant that grows on Mauritius with a  capacity of 4 million passengers. The terminal covers an area of 57,000 square meters and is equipped with five boarding gates with airbridges.

The 3000m2 Renovated Boarding Lounge located in the old Terminal Building was inaugurated on 16 May 2019. This new lounge area offers innovative and convenient facilities for passengers and increases the annual passenger handling capacity of SSRIA to 4.5 million.
