NBC Chicago reports United will no longer allow kids 5 to 11 to fly without an adult on flights that include connections. It also says its optional service for unaccompanied minors ages 12-17 will only be offered on nonstop flights.
It made the changes two weeks ago. United also charges $150 extra, each way, for children flying alone.
United's new policy for young children is similar to policies at US Airways and Southwest. Delta Air Lines and American will still help young children who are flying alone get to connecting flights.
