Which classes are upgradeable?

Which classes are upgradeable to BC? I know M, S and Y are upgradeable but was wondering about K and Q class.

Perhaps the forum moderator should create a "sticky" which lists all the classes and which are upgradeable and which are not since I am sure this has been raised before.

As you mention, M/S and Y are upgradeable.
K and Q are not.
Q/B used to be upgradeable but (unfortunately) they stopped that a couple of year ago.
Not sure a sticky is needed for this since there are only 3 upgradeable booking classes.
Question has come up before but only a couple of times.
