I booked a 12-18 year old as a "child" instead of an "adult" via a 3rd party agent.

1. 3rd party customer service is not responsive to the issue.
2. The Copa fares for adult and child tickets are are identical.
3. All info is correct on the ticket, name, age. It's just the Fare Type that I got wrong.

Will this be an issue at the airport during check in?
