these are eye watering and you have to book them before the flights are on sale...I researched what was said about CoSport who had London Olympic ticket agency and there is a trip advisor site which makes it very clear that they were a nightmare..selling people tickets that aren't together and so on. I just looked at judo elimination rounds and the tickets 250 Reals and they are selling at €250!! we think we have decided against it now. Pity.
