Discussion elsewhere on the web about Jakarta airport's operator reducing the PCN, meaning a fully loaded B773 is too heavy and thus Garuda will have to fly Jakarata-Singapore, refuel and then fly onto Europe. In the other direction refuelling would not be necessary.
I'm very dubious that an Amsterdam-Gatwick-Amsterdam tag-on brings in positive cashflow compared to sitting on the ground at Amsterdam for a few hours or taking feed from KLM, but I don't have access to the confidential numbers so can only make an opinionated guess.
Anyone have any thoughts as to whether Garuda will still be flying to London (Gatwick, or even Heathrow) beyond late October 2015 ?
