TOULOUSE, FRANCE - SINGAPORE Airlines has taken delivery of its fourth Airbus A380 plane, the world's biggest passenger jet, which left Toulouse, France, on Saturday, Airbus said.

The aircraft, delivered 'on time,' will service the first commercial link between Singapore and Tokyo, and is due to start flying the route on May 20, management said.

The three giant airships already in the skies service London and Sydney flights.

As with the existing craft, Singapore Airlines has restricted its 853 capacity to seating for 471 passengers, including 12 suites with full beds.

The first A380 jet arrived in Singapore a year and a half late, in October 2007, after it was delayed by problems including electrical wiring glitches.

It launched the first commercial flight from Singapore to Sydney later that month.

A second delivery took place on January 11 with the third at the start of March.

Two more from among 19 ordered are due to be delivered by the summer.
