Garuda Indonesia will pull the plug on its non-stop flights between Jakarta and London in October, as the airline looks to stem the flow of red ink across its balance sheets.

As of October 28 2018, Garuda's sole European destination will be Amsterdam, with flights operating six times a week. SkyTeam partner KLM is understood to be provide the final one-hour leg to London.

"We will work closely with our airline partners to assist our valued passengers affected by this change to ensure that we are able to rearrange their itineraries and re-accommodate them through our Amsterdam-Jakarta route or other alternative flights," Garuda Indonesia said in a statement.

Garuda currently flies its flagship Boeing 777-300ER jets between Jakarta and London just three times each week. It's understood those jets will be reassigned to the Melbourne-Bali and Jakarta-Tokyo routes

The Jakarta-London Boeing 777 service has proven to be unprofitable for the airline and was plagued with teething troubles and a series of delayed launches.
