Latam airlines B787 has two different aircraft liveries. One features LAN (old version) and the other features LATAM (new version).
In the B787 aircraft, business class is arranged in a 2-2-2 flat-bed configuration. So window seat passengers do not have direct aisle access. For me who enjoys sitting by the window, I would have to cross over my fellow seat mate mid-flight, when he is in the sleep mode.
Meals are of good quality. Mid-flight, flight attendants are mainly in the galley and do not walk around the cabin.
Business class passengers receive a good quality amenity kit on international flights. The only domestic flight that Latam operates with business class is Santiago to Easter Island. For that, only a subpar quality amenity kit is provided. In Santiago airport, the domestic terminal does not have a lounge, so business class passengers on this particular flight do not have lounge access.
The best feature in business class - flat bed !
Pre-departure champagne & nuts
Amenity kit on the international sector
First of two meals on the MEX-SCL sector
On my way to Santiago, South America !
Breakfast on the MEX-SCL sector
In conclusion, Latam features a great business class product on their B787. Amenities and meal service are sufficient. The only negative is their 2-2-2 seating arrangement. Paying about ~S$1600 on a 4-sector business class on its B787, I guess this is as good as it gets.
