What do the letters mean on the screen at boarding?

I guess: Booking fare class, Seat number, Number of bags, Male/Female and ??? (including some status PLT and GLD), Sequential number

'NB" would have to mean "Nobody Bronze" ...

What was in the column that's erased out?

I'll have a stab, it's like playing crossword...:

• First column, unsure - possibly flight class.
• Second column - Seat #
• Third column - NB = No Bags, 1 or 2 bags.
• Fourth column with lots of sub columns:
  • 1st Sub - M/F - Gender
  • 2nd Sub - ET or IB - not sure
  • 3rd Sub - PRCH, ETI, IEB - not sure but note some PAX have a few of these
  • 4th Sub - Status - I see Platinum/Gold, not sure the others but listed is only business.
• Fifth column - Sequence # (of when you check in).
• The rest....I've no idea, I guess I wasn't that helpful after all.
