The order in which the teams came to the mat is:

1-4. Kisha/Jen, Zev/Justin, Amanda/Kris, Gary/Mallory (the order of these four is unclear)
05. Flight Time/Big Easy
06. Jaime/Cara
07. Margie/Luke
08. Ron/Christina
09. Mel/Mike
10. Kynt/Vyxsin
11. Jet/Cord

Jet & Cord were FAR behind. If it were not for a TBC leg, they definitely would have gotten eliminated.

The teams that came to the mat first actually got lucky, because the other teams had gotten on a flight that was scheduled to come before them. But this flight got delayed, allowing these teams to jump ahead.

On the second part of the TBC leg, the teams had to sign up for a charter flight to Broken Hill. The six teams that got on the 6 AM flight are:

Jen/Kisha
Mel/Mike
Jaime/Cara
Margie/Luke
Zev/Justin
Kynt/Vyxsin

The other teams are 30 minutes behind on a 6:30 AM flight. These teams are:

Gary/Mallory
Ron/Christina
Flight Time/Big Easy
Amanda/Kris
Jet/Cord
