Singapore Airlines Ltd. has decided not to extend the lease on its first Airbus Group SE A380 jet, the world's biggest passenger plane.

The lease on the first A380 jet "expires in October next year and we have decided not to extend it. Decisions will be made on the four others later," a Singapore Airlines spokesman said.

The Singapore flag carrier has 19 of the double-deck jets in its fleet and the first five were taken on a 10-year lease deal with Airbus. Singapore Airlines also has five of the jets on order, which will start arriving from the second half of next year.

Initial production aircraft are generally less favored by airlines as they are heavier and often come with troubles. Singapore Airlines was the so-called "launch customer" for the A380, and the first of the jets started flying with the airline in October 2007.

Airbus said the company doesn't comment on individual airlines' fleet plans.

"We are confident in the market for secondhand A380s, which can be leased or acquired at attractive rates. This will offer a great opportunity for new entrants with new business models to start operating the A380," a company spokesman said by email.

A total of 13 global carriers, including Emirates Airline, British Airways and Qantas Airways Ltd. fly the A380, which can seat about 525 passengers in a typical three-class layout.
