Points and Miles Game Language and Acronyms

 The Travel "hacking" or Points & Miles community has it's own language, and it can be very darn confusing trying to figure out what people are saying half the time, unless you are familiar with the common (and some not-so-common) terms and acronyms used.  I've tried to help newbies and veterans alike by collecting a list here.  If I missed any, let me know in the comments and I'll add them!

• 5/24: The Chase 5/24 Rule
• AAoA: Average age of Accounts. This refers to the average age of your credit accounts, which is a key component that goes into calculating your credit score.

• CB: Credit Bureau. The 3 major ones are Experian, Equifax, and TransUnion.
• CIC (sometimes "CIBC"): Chase Ink (Business) Cash
• CIP (sometimes "CIBP"): Chase Ink Preferred (not to be confused with the Chase Ink Premier, which earns URs, but they cannot be transferred to any travel partners, and even worse, can't be combined with your other URs! Highly advised to not get this card to play with points and miles)
• CIU: (sometimes "CIBU") Chase Ink (Business) Unlimited
• CK: Credit Karma
• CL: Credit Limit
