folks, a friend is trying to fly SIN-EZE using SQ miles. currently, the ticket gets her SIN-FRA-EZE. however, she is unable to delay the return by a couple of days due to lack of availability (i didn't check if it is EZE-FRA via LH or FRA-SIN presumeably via SQ).

i can think of 2 alternatives:

(1) SIN-IAD-EZE via UA (which she will probably reject!)

(2) try to redeem a biz class ticket if she can afford it

can anybody else suggest alternatives?
