Planning a jolly to Oz with the clan of four. Eyeing up our options, departing from the wilds of Inverness. Surprisingly, every permutation seems to hit the wallet equally hard.

But, there's some good news, we can leverage BAH to snag a rental car and notch up those tier points.

Flying J on the way out all the way to SYD - return in Y but having a few days in SIN on the way back. (this is the one I am leaning towards)

Flying out W direct to SYD and returning in W.

Flying out W to SIN then W to SYD and same break on the way back, again in W.

Flying out J to SIN then Y to SYD (on SQ as it's a day flight) and same on the way back Y on SQ then J on BA,

What are people's thoughts on W to SYD? How is the cabin for sleeping (it would be BA15 so the 777) the SIN option is the A380.

Another option is AY from EDI - obviously losing the BAH bonus but is their W product any better than BA (also about 20% cheaper than BA)?
