Flights were excellent, both ways. Pilots very kind commenting about the weather and the route, which is very important. Flight attendants are very kind too. But airlines are getting a little bit restricted in terms of what they are reducing. You have to pay for luggage, for seats, for food and tickets are more expensive than before. This makes you feel a little bit abused.
In-flight entertainment has to be updated and/or offer better contents.
On the other hand it will be good to see newer airplanes in LATAM Argentinean´s fleet; I know this because I travel very often. CLARIFICATION: This last comment has nothing to do with flight safety which is, in my opinion, guaranteed.
