Ahhhhhhhhhh ........... they get a cut !
If they do .... that would explain the reactions/responses I was getting from the checkout staff. On a number of occasions they hit me $30 - $50 bucks in excess. Just last week I saw a girl @ cairns airport given the option of unloading things from her cargo luggage and putting them in her carry on luggage to reduce (she still had to pay excess on the cargo bag) her excess or leave it as is and pay full excess .... she unloaded !

But what sort of a crap option is that anyway ? For one you gotta unpack your stuff in front of everyone waiting 2. You piss everyone off who is waiting in line 3. You slow the line down ....... and the plane is still carying the SAME weight. Maybe there is something to do with ballast weight vs cabin weight ?????
But whatever the case ...... seems Jetstar wont be seeing too many kiters in the near future
