We saw Nicky/Kim trying for this in the spoilers, but I guess that flight was full...
QR 96 from Vienna to Doha, 22/1555-2215
QR 120 from Doha to Abu Dhabi, 23/0235-0435
Leo/Jamal dodged a massive bullet! Here's the flight Travelocity offered:
AB 8137 from Vienna to Dusseldorf, 22/1915-2045 (actual 2040-2212)
AB 7460 from Dusseldorf to Abu Dhabi, 22/2130-23/0550
The first flight got delayed which would have left them stuck in Dusseldorf overnight.
The next best flight would have got them into Abu Dhabi at 7.05pm!
It was a non-elimination leg; what would the producers have done with a team 13 hours behind?
They smartly booked an earlier flight on a different airline to Dusseldorf:
VO 155 from Vienna to Dusseldorf, 22/1735-1910
AB 7460 from Dusseldorf to Abu Dhabi, 22/2130-23/0550
The other teams took these flights:
AB 8359 from Vienna to Berlin, 22/1505-1620
AB 7494 from Berlin to Abu Dhabi, 22/2250-23/0600
