My question involves a child custody case from the State of: Arizona

My ex husband is refusing to tell me flight information and the address he will be staying with our daughter for a week. He said he is going to NJ from Dec. 30 to Jan. 5, and that was all he is required to tell me. There is not a specific section in the online parenting plan we agreed to at the time of the decree. Is there anything I can do to get the information on where he is going and what flight she is on so I know she is safe?
