Tried out
http://matrix.itasoftware.com where it is easy to change POS (don't know if it works...)
STOP PRESS: Found ut just now that searches on BA.com suddenly comes up with a lot of I-class tickets (both OSL and CPH - at least in November). Might have been as Sixth Freedom said, that they were not loaded, or maybe some sort of adjustments going on all the time depending on sale and demand?!?! (Both BA and seatcounter showed 0 on the same dates yesterday.)
Anyway - thanks for the info - allways nice to know how things work! ^
