Airlines started imposing what's commonly known as a "fuel surcharge" onto the overall cost of air tickets when they discovered the rising price of crude oil (and thus aviation fuel) was eroding into their profit.

However, since then, companies like CX has been putting up their ticket prices significantly on both short and long haul flights. Presumably some of the increase was to cover the cost of purchasing the then expensive fuel.

Now that oil prices have returned to a more normal level, shouldn't we be asking for a fuel rebate? Or can I look forward to a reduction in fares?
