for a Recap of last night first half....
The teams left the pit stop and had to go to a nearby train station for their next clue and walk through some people in religious garb who were twirling around in some type of religious ritual. J/U left first at 10:45 p.m. approximately. G/M were about an hour later (they lost a LOT of time last week) and R/A were 45 minutes after them. R/K brought up the rear about 10 minutes behind R/A.
The clue told them to go to London. All teams caught up at the airport since the flights didn't leave until the morning. J/U booked a direct flight on Turkish Air to London. G/M booked the same flight. It is not clear if they looked for a faster flight with connections. They did show J/U talking and he wanted to check connecting flights but she said that was too risky, that direct was their best bet. So, I don't know if they knew about the faster flight or not. They didn't show G/M even trying to find a faster flight.
R/A used the Internet and found a faster flight connecting in Frankfurt. They then purchased tickets on the direct flight to try and fool R/K. However, Kelly saw the flight on the departures board and they were able to arrange to get on that flight. It was risky though because both teams were put on standby for the left from Frankfurt to London.
In Frankfurt, it was a foot race to the counter to get to the top of the standby list. R/A won and got there first on easily got on the flight. R/K were also able to get on the flight through standby, so the gamble paid off. They got to London about two hours before the other two teams on the direct flight.
R/A met a guy in the airport and he offered to help them out. He was very good at the train system, and seemed to know London very well. All the other teams took taxis, but the train appeared to be much faster (though confusing).
I think that was all in the first hour, I hope I didn't miss anything....
