I am curious. I can get a Saver Economy award from MXP-SIN no problems (and always have been able on the date of interest) however have waitlisted on the same flight BCN-MXP-SIN and it just doesn't want to clear. Given that it is same flight, same plane and SQ can't sell BCN-MXP on it's own, if it makes redemptions from MXP-SIN available why not from BCN as well?
