The fact is that on a BA award ticket BA charges whatever carrier imposed surcharges the operating carrier charges on a revenue ticket, whether it be coded YR or YQ. Whether this is labelled a fuel surcharge or carrier surcharge is really irrelevant as the consumer is really just interested in the total cash component.
I'll have to take your word for the first part since I haven't seen that published, but I agree with your second point.
Can you point me to something that says BA passes along all carrier fees?
BA also no longer calls their YQ charge a fuel surcharge but rather a carrier surcharge, but personally I would not claim that BA "does not charge a fuel surcharge on BA redemptions" just as I would not say that BA "does not charge a fuel surcharge on CX redemptions" as you claimed.
We are talking aboout a YR fee here--not YQ. There is a difference. What I said above is:
My understanding is that it is a YR charge, which can be a fuel surcharge, or it may not be. It is an independent carrier charge.
If you have something that demonstrates a YR fee on CX is always a fuel surcharge, I'd been glad to be corrected, but it really doesn't matter in the overall scheme of things.
BA charges hundreds of Pounds for a fuel surcharge in a booking and a CX booking is about 15-Pounds for whatever it is. The result is that I find CX bookings using Avios a pretty darn good deal.
YQ is a fuel surcharge. YR
may be, but is not necessarily so.
What you did when quoting the BA fare breakdown in post 19 is take what is labeled a "Carrier Imposed Charge" and unilaterally altered it to support your argument to "Fuel Surcharge". That is not what it says on the fare breakdown so I would not say that.
Yes, the carrier imposed surcharge is low on a CX redemption but it is still present as highlighted above. CX could increase their YQ to any amount (subject to local regulations, ex-HKG they are restricted for example) and BA would pass this on.
It is not a YQ fare component we are talking about here. It is YR.
