MANILA--Cebu Air Inc. (CEB.PH), the Philippines' largest budget carrier by revenue and fleet size, said Wednesday it formally signed in London a $280 million long-term maintenance deal with Rolls Royce Holdings PLC (RYCEY).

Rolls Royce will service the Trent 700 engines in Airbus A330 aircraft purchased by Cebu Air, also known as Cebu Pacific.

The deal was among three business agreements signed Tuesday during President Benigno Aquino's U.K. visit.

Cebu Pacific first announced in February its intention to select Rolls Royce's TotalCare support services shortly after declaring its plans to buy A330s for delivery by 2013 for its planned long-haul operations.

The A330 is the first aircraft in Cebu Pacific's fleet to use the Trent engine.

Cebu Pacific plans to buy up to eight A330s to service routes to Europe, Middle East, Oceania and the U.S.
