Good to know how Garuda is investing and improving their premium class by leaps and bounds! I think it is due to their alliance with Etihad.
However, my flights with them have been inconsistent for the last 12 months. Range from good to really scary. Had a rough landing on one of their domestic legs just last month, and 2 months ago, I was served a black corn on a SIN-CGK flight!
As for the F suites, I think they will also be introduced to the CGK-LHR routes later this year, so GA is also aiming for the Kangaroo route LHR-CGK-SYD with the new F.
