Religious Travelers - Kosher Airline Food out of S. America

Just wondered if anyone can share any experiences of kosher airline food out of S. America. Who provides the meals? How do they compare to say Harmolis etc. I will be flying out of Buenos Aires on a couple of short hall flights and out of Montevideo on a flight to the US. All business class.

Thanks in advance

I see there are no replies. Do you now have personal experience you can report on?

Its been a couple of yrs, But I experienced no Special meals even in Biz on short hauls.

havent been to BA but out of most other places if there was a meal it was those LongLife type. Sometimes a reg meal from the US was supplied

AV was pretty good, didnt use US Carriers Taca or Lacsa Nothing at all

Kosher from Argentina, is provided by Open Kosher under Ajdut Kosher, Rabbi Daniel Oppenheimer, orthodox, from the german community, in Belgrano.

From Chile, is Shemtov Kosher, with Horowitz as a supervision. Very good, Excellent food.
