Too early Apskip. We know front-runner teams Dave/Connor and Pamela/Winnie (second place!) went through Melbourne and Perth on these flights:
DJ 63 (19 1608-1735, sch 1600-1750) from Christchurch to Melbourne
Dave/Connor: QF 653 (19 2033-2129, sch 2015-2120) from Melbourne to Perth
Pamela/Winnie: DJ 697 (19 2131-2247, sch 2000-2105) from Melbourne to Perth
QZ 8411 (20 0438-0825, sch 0450-0830) from Perth to Bali
Max/Katie also arrived in Bali at the same time. The simplest method is:
EK 419 (19 1653-1808, sch 1655-1815) from Christchurch to Sydney OR
DJ 73 (19 1700-1831, sch 1700-1830) from Christchurch to Sydney
DJ 569 (19 2013-2203, sch 2000-2200) from Sydney to Perth
QZ 8411 (20 0438-0825, sch 0450-0830) from Perth to Bali
Joey/Meghan and at least one other team were sighted exiting the Bali airport parking lot at 11am. There are two flights arriving from Singapore within the hour, and plenty of ways to get from Christchurch to Auckland. I think there should be enough flights for no team to get left behind:
From Christchurch to Singapore
EK 419 (19 1653-1808, sch 1655-1815) from Christchurch to Sydney
SQ 242 (19 1932-0028, sch 1910-0015) from Sydney to Singapore
OR
JQ 166 (19 2046-2218, sch 2100-2240) from Christchurch to Melbourne
SQ 218 (20 0109-0542, sch 0105-0540) from Melbourne to Singapore
OR
NZ 546 (19 1931-2047, sch 1935-2055) from Christchurch to Auckland
SQ 282 (20 0102-0633, sch 0105-0635) from Auckland to Singapore
From Singapore to Bali
VF 241 (20 0759-, sch 0725-1005) from Singapore to Bali
GA 841 (20 0815-, sch 0750-1035) from Singapore to Bali
Some (but not all) less efficient itineraries, if best flights are full
From Christchurch via Melbourne or Sydney to Perth as above
GA 727 (20 0713-, sch 0713-1100) from Perth to Bali
OR
From Christchurch via Auckland, Sydney, or Melbourne to Singapore as above
QZ 8499 (20 0931-1208, sch 0915-1205) from Singapore to Bali
TL;DR: Dave/Connor, Pamela/Winnie, and Max/Katie are first arriving in Bali. The majority of teams is likely to arrive two hours later on one of two flights via Singapore.
