About a month ago we published on Aviacionline.com an article about the return of Edelweiss Air to Buenos Aires. At first, it was planned for November 1, with two weekly frequencies to and from Zurich on Airbus A340-300s. Finally, the Swiss company made a new modification in its schedule, and it was confirmed that Edelweiss will not return to Argentina this year.
According to the reservation system, Edelweiss Air will resume operations between Zurich and Buenos Aires on January 4, 2021. Initially, the company will have a weekly flight between both cities on Airbus A340-300s, with a capacity for 314 passengers.
For the month of April, Edelweiss plans to have two weekly frequencies between the airports of Zurich and Buenos Aires.
