It is always surprising to see how accurate FT is. Everything state above is pretty much accurate.

I was going through the wiki and everything there is accurate. A few corrections though:

ONE is a ZED ticket issued for a OneWorld employee. ONE tickets list above ZEDs for standby. ARMD is still used.

I also have some to add:

PPR- Complimentary upgrade (ie as a result of oversales or a service recovery tactic, does not remove stickers from the traveller's account).

PRAC- Priority AAcess

The Oneworld alliance designations are no longer used. An Emerald will show up as an EP on the manifest.

Very careless of the FA though.
