Since I used to be a United 1K, let me translate CO for you.

United = Continental
-----------------------
NF = R

NC = Doesn't exist. CO is a 2 class operation only. On intl flights that offer BusinessFirst, NC = R

NY = Doesn't exist. No such benefit at CO. Platinum Elites get expanded BusinessFirst Award inventory allegedly. I have never taken advantage of this.

The only way that I know of to see R inventory is to check " onepass reward upgrade" box.

If you are a Platinum Elite, buying an M fare and hoping for an up, this comes from Z
If you are a regular Elite (Gold or Silver) hoping for an up, this also comes from Z

XY, XC, XF = This follows Star Alliance Codes... X, O and I (if i am not mistaken)


And finally, for terminology sake

UDU = EUA

CR1 = Doesn't exist. I look forward to having this around next year, for p.s flights

SWU = SWU

e500s = R.I.P

RCC = PC

.bomb = We actually like our website no?

purser = International Service Manager

2P = Silver Elite

1P = Gold Elite

Undefined on United (as of 2010-11) = Platinum Elite

1K = Doesn't exist

GS = Presidential Platinum

1K Voice = Doesn't Exist

1K Desk = Actually the Silver + Gold and Platinum's use what we call the "Elite Desk". Authentication is via
Onepass number. Pres Plats get different people to handle them.

Doesn't Exist on United = Alex (the handy know it all who lives at Continental.com), on the top right hand corner of the screen

You get the drift.....I actually could go on. Feel free to add on
