Trying to find a weird use case for Emirates.
If you have a 1st class ticket, you're allowed 50kg for a flight from SYD to AKL/WLG/CHC.
However, I can't find out how much additional luggage would cost trans-Tasman if you've purchased a 1st class ticket.
Weight limits seem to be here: https://www.emirates.com/au/english/before-you-fly/baggage/checked-baggage.aspx but I can't find costs.
Eg an extra $$xx per yyy kg?
