Garuda Indonesia is selling four Boeing 737-400s as it no longer needs the aircraft.

The national carrier has issued a notice announcing that the 737-400s are up for auction, and that interested parties can inspect the aircraft from 23 November to 2 December.

"We are getting 50 737-800s and 10 Boeing 777s, so we have no need for these 737-400s," says a Garuda spokesman. He adds that the airline wants a younger and more fuel-efficient fleet.

In recent months, the airline has been receiving Airbus A330s and Boeing 737-800s on lease. Today, it is holding a ceremony in Jakarta to mark the delivery of its 17th 737-800 and 10th A330, says the spokesman. It will have 20 737-800s by year-end, he adds.

According to Flightglobal's ACAS database, Garuda has 19 737-400s. It owns seven and all of the 737-400s were built in 1993.
