Thank you. I figure it out. I cannot do price assurance on orbitz because the number of passangers do not match. Even if the trip matches you need to have the same number of passangers. I guess this sucks, because it's not really price assurance per ticket.

I just can't believe how low the fares to europe are right now for august/sept. I would have never thought that a ticket will go down to $650.
