Special Passengers | Infants (INF)


    This chapter takes into consideration information regarding bookings, fares and issuance for Infant passengers (INF).

    Each type of passenger corresponds to:

    Type of Passenger


    Infant (INF)

    Any and all person under the age of 2.

    Child  (CHD)

    Any and all person under the age of 12. When travelling without the company of a person over 18 this passenger is considered an Unaccompanied Minor.


    Any person aged 12 and under 18. An emancipated adolescent is considered an adult

    Double discount for minors on individual bookings is not allowed.

    When operators wish to apply negotiated discounts on individual bookings (e.g. one deal associated with a tour code) they cannot be added to discounts for passenger type (CHD/INF). In other words, operators must choose a single discount for issuance. Therefore:

    • When choosing a negotiated discount (for example; one deal), issuance will be linked to a tour code and tickets for minors must be issued applying the adult discount, preserving the INF code next to the name on the ticket.
    • In the event a ticket has been issued with a double discount, it will be penalized; charging the applicable difference for the route according to passenger type, plus the administrative charge associate with ADM issuance in the corresponding markets.
    • Exceptions to this definition are covered when pricing will be given automatically.

    Please note: Independent of whether ADT fares are used on the booking, the minor must be identified as CHD/INF to comply with airport and safety protocols.

    Infants are considered minors up to 2 years of age minus one day at the time of travel.

    General Considerations

    • It is mandatory to request the date of birth and age of the infant when generating the reservation.
    • Minors turning 2 years old during the trip must travel with a seat confirmed on LATAM flights and in combinations with other airlines. Passengers may choose between 2 options:
      • To travel as a CHD (round trip).
      • To travel as INF in the departure leg (OW ticket) and as a CHD on the return leg (OW ticket).
    • [NEW]: In order to give visibility at the PNR level when disassociated or not issued Tkt INF are detected, the following alert message will be inserted in the PNR's: PLS ADV REISSUE INF TKT BEFORE CHECKIN. Reservations under these conditions must be regularized.
    • Infants under 7 days must obtain Medical Certification to travel.
    • Infants must always travel accompanied by a legally responsible adult (18 years or older) or with an emancipated  adolescent. If traveling with one parent, the parent might be under 18. There are some exceptions. It is recommended to check any restrictions directly with the authority of the country of origin and destination of travel.
    • If the adult responsible for the infant requests a special service,  the adult must be able to:
      • Understand or follow safety instructions
      • Assist in case of an evacuation of the aircraft
      • Address their physiological needs (feeding and personal hygiene).
      • Adults traveling with infants are responsible for the infants’ meals.
    • Issuance of infant tickets (INF), after the issuance of the ticket of the adult companion in charge must be requested directly to LATAM


    The fare applicable to INF tickets (without seat assignment) traveling with an adult already ticketed will be as follows:

    • In a new reservation, issue the INF fare in the same class as the ADT ticket.
    • If the class is not available on the same flight, issue the INF ticket on another date keeping the same route (the flight number may differ).
    • If the same class is not available on the ADT’s original flight or on any other flight, you may issue the INF ticket in the lowest class in the same cabin as the ADT (on the same flights and dates as the original).

    In all cases, fill the Endorsements/Restrictions field with the text: INF DIFF ADVP. If the new INF ticket issued at a fare equivalent to the ADT does not meet the AP, the ticket may be issued manually in order to ignore the ADVP.

    Once issued, the INF reservation must be cancelled and an SR CKIN must be added to the original ADT reservation with the INF ticket number, and then the new reservation must be cancelled:

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

    Remember there are no fare or service fee charges for INF tickets on Brazil domestic segments with an ADT ticket already issued.   

    - All reservations of INF traveling as CHD must have a mandatory SSR CKIN with the date of birth and age of the minor; indicating that the INF is travelling as a CHD. Example: INF 10 MONTHS TRAVELING AS CHD DOB10FEB2017.

    - Infants traveling with a seat must pay CHD fare and have one of the following devices:

    - CRS (Child Restrain System): Is a safety seat with a hardback support for infant passengers, approved for use in motorized vehicles and aircraft.

    On LATAM Airlines Brasil one CRS per aircraft is offered by company. In case is already taken, passenger has to use his/her own device. On the other markets the device has to be provided by passenter.

    - CARES (Child Aviation Restraint System): Consists in a harness installed around the seat’s back support in the Economy cabin. It is fastened with the seat’s safety belt to restrain the torso.

    CARES has to be provided by passenger. 

     To use these devices it must be considered:





    ·         Infants weighing between 10 and 20 kg.

    ·         Can only be used in Economy and Premium Economy.


    ·         Must have the following manufacturer label reading: "This restraint is certified for use in motor vehicles and aircraft" or "FAA Approved for Aircraft Use Only"


    The Travel Agent must warn passengers of the use of these devices and the warning must be indicated in the reservation on an OSI: PSGR WAS ADV ABOUT CRS SEAT FOR INF.

    On LATAM Airlines Brasil CRS request for travel agencies will be supported by Contact Center. The request has to be performed as usual by Interact. Once is confirmed or denied Notify SSR area will advise agency about request status. It is very important phone number is added to the reservation at the moment of the service request and, if possible,  should be inserted one more option (another phone number).

    • Cannot be placed in the Emergency rows, or in the previous or subsequent rows.  
    • If it uses CRS¹ (Child Restraint System) on board:  
      • If it goes in lateral block, assign window  
      • If it goes in a central block (between two aisles), assign a middle seat.  
      • Never assign aisle  
    • Assign seat that has additional oxygen mask. Our aircrafts have 1 additional oxygen mask for each block of seats. 


    ATTENTION: B767 only has additional masks in: 

    • Premium Cabin: first row and seats of the central blocks. 
    • Economy Cabin: first row and seats of the central blocks. 

    Sabre restrict the allocation of an infant for each block of seats according to the amount of available oxygen masks


    • Airbelt: Air belt is a safety belt with an airbag on one of the belt straps; the airbag is deployed on impact represents a potential risk for certain passengers. Air belt seats cannot be assigned to:

    • The discount to apply might vary depending on the route and is reflected in the fare regulation. When there is an INF discount, they do not have the right to a seat on the aircraft.
    • If the purchased fare does not have a discount for INF, it must be sold as CHD assigning a seat to the infant, without exception.
    • INF fares only apply while the passenger maintains his/her infant status. If in any segment of the itinerary it becomes a Child (CHD), the Child fare will apply.
    • An INF travelling in one direction of their respective trip must be charged the available OW INF discount fare for whatever points the fare applies.
    • Up to 2 infants are allowed per adult, but only one of them is entitled to the INF discount. The other INF passenger will travel with assigned seat and must pay CHD fare. If the route and fare do not allow CHD discount, adult fare must be paid. The reservation must be generated with the ticket designator CHD and assign a seat.
    • Infants travelling in Premium Business and Premium Economy have no discounts; Therefore, they must pay the full adult fare. It should be reserved as a CHD and a seat must be assigned.
