Hey guys, need help. Is it ok for a New Zealander (currently living in NZ) to buy their tickets from the Australian airline Qantas airline via website? Also, is it okay to not register for Qantas Frequent Flyer? wanting to buy a ticket from New Zealand to Sydney to Thailand and then return ticket.

I'm wanting to buy my flight tickets with Qantas for travelling as it's much cheaper and offers more return dates at cheaper prices. I assume if I were to buy tickets with Qantas airline via online without their Qantas Frequent Flyer membership , they would send me a confirmation of my boarding ticket via email? wanting to buy a ticket from New Zealand to Sydney to Thailand.

I'm a bit worried on if i were to get refund, it wouldn't be simple.

any help would be much appreciated thanks
