So how is it that CX (not part of the TATL JV) has considerably lower fees on a BA TATL award booked using CX Asiamiles ex-USA than
either AA
or AS?
(note that this doesn't apply the same way ex-UK/EU, the YR on award tickets goes down quite a lot)
I would also suggest comparing round trip pricing if you book:
USA-UK/EU-USA
UK/EU-USA-UK/EU
For instance, the first screenshot is booked as
the return on an AMS-PDX-AMS round trip. The second as a one way,
same date, flights and class of service PDX-AMS.
