Well, they can change a HKG/PEK ticket from $3000 fare + $1000 surcharge to $1000 fare + $3000 surcharge given they aren't regulated at all. Essentially your miles help you save $1000 instead of $3000.
Take ex-LON (e.g. BA) as an example, many long-haul econ tickets are only around 100gbp whereas the remaining are all fuel/airline surcharges...
