Being a new member, all these acronyms are pretty hard to decipher.

CO - i.e. "How long does it take to transfer to CO and may it be in anybodys CO account name?"

W - i.e. "This is useful when trying to book the lowest booking code eligible for upgrades on certain airlines (for example W on UA)."

MF - i.e. "My MF isn't due until Dec 1st and I'm hoping to confirm that the MF get 2x points before I pick which card to use. "
