With the removal of the minimum fares on domestic flights last August 2018, LATAM Argentina reported that from 1^st  September, 2018 a new travel model in the country will be implemented.

There will be four fare options: Promo, Light, Plus and Top, so that passengers can chose and pay for the services they would like to use.

Following this, passengers traveling on a domestic flight in Argentina will be able to travel with their free 8kg carry-on, but at the same time, they will have the possibility to add additional services in each category, depending on the restrictions that apply in each fare. The important part is that it will always be a cheaper option to pre pay for these add-ons online than adding them at the airport counter.
