Can anyone help decipher this for an LH flight? I have looked in the FAQ section and done a couple of searches, but didn't find the key to these codes. I think I can figure 'R' is reserved, 'W' is probably the aisle, but not sure of the other codes.

Just pasted that front economy cabin from the 343.

This is the text Worldspan TravelASP:
