FYI - This is to inform that effective January 8, 2018 the fare for infants (no seat assigned) traveling with an adult who already has a ticket must be as follows (valid for international flights in Economy cabin): 

• In a new reservation, the INF must be ticketed in the same class as the ADT. 
• If the ticketing class is not available on the same flight, the INF must be ticketed on another date, maintaining the same route (the flight number may be different). 
• If the same class is not available on the ADT´s original flight or any other flight, the INF may be ticketed in a lower class of the same cabin (for the same original flights and dates). 

If the new INF ticket issued at the same fare as the ADT does not comply with the "ADVP" rule (time limit for ticketing), it is going to be possible to force manually the fare and to ignore de ADVP. 

In all cases, the Endorsements / Restrictions box must be checked with a note: INF DIFF ADVP. 

Please remember that INF ticketing on domestic segments in Brazil with the ADT ticket already issued remains unchanged, i.e. there is no charge for service fee or fare. 

Once issued, the INF reservation must be cancelled and an SR CKIN with the INF ticket number must be added to the ADT´s original reservation. 

E.g.: SR CKIN -  INF (name of INF) TKT 957-9876543210 ACCOMPANY ADT 

This will be updated in the chapter Minors in Mundo LATAM since the application date.
