I guess this situation is different from the FCO - DUS sale, were you could fly all over the world on lots of airlines. It was all over the blogs and was open for an entire weekend. They got all bad news about this issue over the news.
The sale of last sunday was only one destination from ex England or Germany, all on Alitalia metal and open for half a day.
I guess the number of tickets sold on this sale is very less comparing to the FCO sale. Maybe this time we got the result in our favour. Just my 2c
