Hi All, hope someone can help. I've got an airpoints business seat from Bangkok to Christchurch next week via Sydney and Auckland. The Auckland to Christchurch leg is a codeshare economy flight on Jetstar. My e-ticket says my bag allowance on every leg is 32kgs. I want to purchase an additional 32kgs which Qantas lets me do online for A$90. I'm hoping I'd only have to pay My problem is that this will not apply to the Jetstar flight in NZ. I can't access Jetstar with my Qantas booking number to buy additional baggage and the Qantas website says I have to deal with it at the airport.
