Cathay Pacific Asia Miles - Question: eligible fare class for upgrade

From Asiamiles website:

Members can redeem mileage credits for an upgrade to the next higher class of travel from the original class of ticket purchased in eligible subclasses.

So, what are the upgradeable fare codes? Maybe I was doing the search wrong, but I could not find anything either here or on cathaytalk. Thanks.

all mileage earning subclasses are upgradable. for economy, they'd be Y , B , H , K , L , M , V.

I still could not find the T/C for upgrade eligibility on the linked page, but thank you for the info. Just want to make sure because some airlines (eg. AA) have mile-earning, but not upgradable fares (I/O/Q).

I confirm what Marcus Lai said. For upgrades on CX the underlying ticket must be mileage-earning, i.e. YBHKLMV in economy. Currently all revenue business ticket classes (JDCI) seem to be eligible for upgrade. Having said that people here have said that certain I-class (deep discount) buiness tickets have been endorsed as non-mileage earning. I would not be sure that such tickets could be updated.

Note that this applies only to upgrades on CX marketed flights using AsiaMiles.
