Via Perth, Singapore, Heathrow, and Gatwick.
Less said the better. No problems with any of the connections or volcanic ash. Had a decent meal on Tuesday night then passed out and had a great sleep in the B&B – the dinner before that was on Sunday night (not counting airline food)
The A380 from Singapore was very good, a bit smoother than the 747, and it has a tail webcam you can access from the inseat entertainment unit. Great for watching dawn over Russia at 12000 metres, I recomend it!
