Perhaps N is the new booking class for Check@Go class. More info about 4 different classes is here: http://www.brusselsairlines.com/en-b...omparison.aspx

And immediately a couple of questions:
1) Do FTL/SEN/HON pax get their luggage allowance honored when traveling on this new Check@Go fare? Or will be like with BA: cheapest fare=no checked luggage regardless of status;
2) What about lounge access?
3) For Check@Go fares, airport check in is not available, instead "Self check-in terminals are at your disposal." What to do in stations like TXL or WAW where LH machine does not recognize SN booking and sends you to "any LH counter" only to be told by the personnel that only specially designated counter opened for a given SN flight will be able to check in for the flight.
4) The other new "Light&Relax" has a very attractive feature "Change to an earlier flight on the same day" with a note "Change to an earlier flight is possible at the airport and subject to availability in the same travel class." Does this mean that SN is following LH in zeroing out anything but Y/J on the day of departure?
