Allright Thanks anyway, I guess I will try to call them again tomorow. I tried to compare fare with ITA Matrix I can only replicate the price of the website (flyclassic) with the E fare.. Not sure if it is reliable...

Update:
I call them this morning FlyClassic bookable on the website was a mix of A and W class, they also confirm me the table of Long Haul does not apply for Short Haul
