Aerolineas Argentinas hot sale 40% discounts to Europe

[Macanudo]

Anyone have an opinion on the current Aerolineas Argentinas hot sale with 40 % discounts? I think it started yesterday and ends tomorrow. I'm looking at a round trip flight to Madrid for around $450. I know there is another thread regarding Aerolinas Argentinas, but thought maybe someone else may be interested in getting a cheap flight. https://baexpats.org/threads/good-experience-on-aerolineas.41031/
