I want to go back to leg 4 and the connection in Frankfurt and how that apparently allowed some teams to get ahead at least 2 hours and others to fall behind. The official connect times (quite absurd according to my experience for international to international) for FRA are:
Domestic to Domestic - 45 minutes
Domestic to International - 45 minutes
International to Domestic - 45 minutes
International to International - 45 minutes
That means that all travel agents, particularly Lufthansa ticketing agents in the Accra airport, would have been allowed to book the connection between LH567 (scheduled arrival 630am June 1) and SK3000 (scheduled departure 0735) of 65 minutes. that is 20 minutes more than the minimum. Now, I personally would never book a flight through Frankfurt assuming a 65 minute connect time due to my personal experience there of slow connection, but if it is a legal connection then the Amazing Race teams certainly should have tried to, and been allowed to.
