I saw an interview with Jamie and Cara. They said the clue said that the mandatory flight left once every 24 hours. So, if they missed the first mandatory flight, the next one was 24 hours later. Kent and Vyxin were lost for 11 hours! But by taking another flight and taking the 30 minute penalty, they actually came out better. It seemed that the clue was clear on the fact that they had to take that specific flight that left once every 24 hours. They also said that when they were lying about their car breaking down, they didn't blame them for taking the other flight and felt bad for them because they didn't think it was their fault. But once they found out the real reason was they got lost, that is when people got upset. I'm not a Jamie and Cara fan but the interview made sense. You can read it at realitytvworld dot com.
