Thanks,
sounds like there is no downside to doing this.
So why doesn't everyone (get the much cheaper RT) than a OW (in this case, 1/3 the price of the OW)?
FYI it needs to be Malpensa.
Another question: how come most of the trip websites i used gave me one stop (3-5 hour) trips from VIE-MXP rather than giving me the OW option (90 minutes)?
