If you do not want your child to travel alone you can :
Use the UM service (“Unaccompanied Minor”) offered by the airlines. This service, provided for children (in other words minors), consists of extra assistance from the airport of departure to the arrival (in other words, until a OUI-CONNECT representative takes responsibility in Los Angeles). This service costs about 100 dollars extra (the price varies depending on the company).
group with other participants so that your children are on the same flight, meet at the airport and help each other during the trip. OUI-CONNECT can put you in touch with other participants.
