Will bring back some memories for me to see "Indonesia" at LGW again.
It used to be multiple stops to CGK (via AUH and BKK on the trips I did in the 90's) and a change there to get to DPS, although I think there were some "direct" (ie, no airframe change) flights to DPS aswell.
They've been advertising heavily in the UK already (eg, Premiership footy matches) so hope they can make a go of it.....getting to DPS from the UK should be easier than it is today considering the numbers of us that go there.
