Just booked a one way saver mixed cabin awardfrom ORD-EZE going on the following segments
ORD-YYZ UA
YYZ- GRU AC
GRU- EZE TK
ORD-YYZ is in Y. Has anyone been offered an SDC on the UA segment in a mixed cabin mixed carrier award when UA is the first airline you are flying? First time I have booked an award like this.
