I am travelling to Yogyakarta in September from London, there seems to be varying advice on the best travel route and which airline to research.
There is an option to fly London - Amsterdam - Yogarkarta (but appears a long flight).
I have seen varying reports of Garuda, many are now quite old mind you, maybe their fleet has improved.
If possible looking at an airline that offers a reaosnable 'premium economy' option.
Any help gratefully received
