Change your LATAM Airlines flight with a Touriyo agent

• Full / Premium Economy Full / Premium Business Full, all: 0 before the flight (fare difference may apply)
• Right after booking: Flights operated by LATAM to, from or within the United States (customer service plan, item 5): 'LATAM will allow reservations purchased to be canceled without charges, for at least 24 hours after the reservation is made if the reservation is made one week or more prior to the flight's scheduled departure.'

LATAM's Colombian rights page states that when the purchase was made through a travel agency, the agency is responsible for the refund under retracto/desistimiento ('Cuando tu compra haya sido realizada por medio de una agencia de viajes, esta será la encargada de realizarte la devolución que corresponda'), and that name errors can be reported 'a la aerolínea o agencia de viajes' for correction. The US customer service plan says that for bookings made through a travel agency LATAM will contact the agency, which in turn contacts the passenger, unless direct contact details were added to the booking. The corporate groups channel explicitly excludes travel agencies as intermediaries.
