Malaysian airline Firefly's chief executive officer Philip See will hold talks with representatives of Changi Airport Group (CAG) today to petition, once again, for Firefly's landing rights in Singapore.

See remained optimistic that his trip today would result in a positive outcome.

"I'm optimistic, but things these days are very fluid," he was quoted as saying by The Malaysian Insight (TMI).

Both countries were embroiled in a drawn-out aviation dispute over airspace to the south of Johor, resulting in the suspension of Firefly's direct flight from Malaysia to Singapore.

The airline failed to secure landing rights at Singapore's Seletar Airport, while its previous landing spot in Changi has been sold to another airline.

Firefly was reportedly slated to move its Singapore operations from Changi to the new Seletar Airport terminal on Dec 1.

However, Putrajaya had on Nov 30 objected to the landing protocols for the new terminal, citing airspace sovereignty.

On Jan 8, both countries agreed to immediately and simultaneously suspend Malaysia's permanent restricted area over Pasir Gudang and Singapore's implementation of the Instrument Landing System procedure for Seletar Airport.
