The passenger went on to say he was travelling with a 13-month-old baby.
The post went on: “Queue us with a grumpy 13-month-old … I asked (Qantas staff), ‘How am I going to organise a travel cot at 2am? Where do I get clean clothes from? Formula?’ No answers and not even a sorry.”
The customer said that he spent 30 minutes on the phone after trying to track down his bag.
A Qantas spokesman told NCA NewsWire: “Due to poor weather conditions in New Zealand, we had to reduce weight on our flight from Sydney to Wellington last night.
“The poor weather meant we had to offload a number of bags, which will be delivered to passengers (on Wednesday).
“While we know it’s frustrating for customers to be without their luggage for a day, this was a better outcome than leaving passengers behind to reduce the weight of the aircraft.”
