    Extra Seat (EXST)

    Is a paid service with automatic confirmation, which consists of the assignment of 1 extra seat for comfort, obesity or medical needs.

    Economy, Premium Business or Premium Economy*

    Cabin Baggage (CBBG)

    For passengers who need to transport special baggage (fragile or large baggage, which due to its dimensions or weight cannot be considered part of the hand baggage allowance) in cabin paying for an extra seat. This applies to: musical instruments, diplomatic bags, works of art, scientific instruments and similar items of a delicate nature.

    Economy, Premium Business or Premium Economy





    (*) Passengers that due to their size must out of necessity occupy the immediately adjacent seat, can only travel in Economy in order to use this service. The configuration of some of the premium cabins  (Premium Business and Premium Economy) have no retractable armrests between seats limiting the use of an adjacent seat.

    • Valid only in itineraries with flights 100% operated by LATAM.
    • There is a maximum limit allowed of 1 additional seat per passenger.
    • Passengers who require this service must have a confirmed seat. On routes where the seats are subject to collection, the passenger must pay for both seats.
    • It must be requested at the time of booking. Passengers who require the service after issuing the ticket must reissue and pay the applicable fare differences.
    • Passengers with these services will be allowed to keep the applicable baggage allowance for each of their tickets (passenger ticket and CBBG/EXST ticket). Eg: if a passenger travels with a FULL fare on a domestic route with a 1PC allowance, he/she will be entitled to 2 pieces: the one defined on his ticket and the one on the ticket where the service is reflected. This eliminates the manipulation of baggage allowance when ticketing. 
    • It only accrue Miles/Points the ticket purchased for the passenger, the EXST/CBBG does not accumulate.

    If at the time of boarding the passenger requires an EXST because it does not fit in the seat, EXST will be charged at the fare available at the time of travel. Except in Argentina for trips on domestic routes where EXST will not be sold or booked, the passenger must arrive 3 hours before the flight to receive a free EXST. Does not apply for connections with international or interline routes.


    2.1 Additional considerations about CBBG

    It must not contain dangerous goods.

    Referential dimensions:

    • 41 cm long + 41cm wide + 90cm high
    • Maximum weight allowed: 45kgs (101 lbs.)
    • The item must not obstruct the vision of the "safety belt", "no smoking" or "exit" signs in the aircraft cabin.

    The item must be fully covered within a suitcase or carrying case with handle. The seat belt will pass through the handle to prevent displacement during the flight.

    CBBG that do not comply with the conditions reported will NOT be boarded in the cabin. The luggage will be sent to the aircraft hold (provided that it complies with the standards of weight and piece allowed to travel in the aircraft hold). The fare regulation of the CBBG ticket will apply.

    The Travel Agent must issue 2 tickets, leaving one of them in the passenger's name and the additional one identified as surname/EXST or CBBG as applicable:
