Does having a mixed cabin throw out the calculation of the points and fees for a reward seat booking?
I'm looking to book a one way trip from PEK to BNE through TPE using the multi-city tool for a relative, and wanted to ask if someone could explain how to the point cost is calculated by QANTAS.
The costs for the PEK-TPE segment are 14k points + ~$100 in Y and 30k points in J. Then for the 2nd leg of TPE-BNE it's 30.2k + ~$140 in Y and 75k in J. Booking the entire route in J only costs 90k in points vs 89k for a mix of Y + J. Total taxes+fees in both mixed and non-mixed cabins came to ~$305.
How come there's no 'discount' if you choose mixed cabin and also why does the total cash fee end up being higher than if added individually? I understand this isn't a glitch or anything wrong on QANTAS's end so just want to understand out of curiosity.
