Thanks for the detailed and informative reply. ^

All tickets were P fares or P/Z fares and were a similar price-point. Since the $7-8 "surcharges" were consistent, I focused on the odd items.

The $108.12 listed under "surcharges" for July last year makes no sense to me from a detail perspective as there is no "Carrier Surcharges" line on the ticket or screen shot of the booking AND it is not charged on the CX ticket from the same time. So, if AC was charging a "peak surcharge" for last July, CX was not on the exact same route.

Also, I still don't know how the "Carrier Surcharge" line item is also missing from all of the September tickets, so I assumed AC built it into the fare.

I posted on this forum last year that HKG was charging an additional fee to cover the costs for the planned third runway. I'm sure that cost is buried in there somewhere.

Thanks again.

P.S. I found the CX chart on their site quite helpful as it breaks it down
