This was the worst flight I’ve been on. Getting on the plane where is was 30 degrees outside was hotter on board cabin must’ve been 33 degrees. This is a health hazard. They cannot be doing this to save on fuel. People could die from this!!. Fans and a/c was, off entertainment was off. Poor excuse given. Crew made the excuse that the system didn’t have enough power. They basically were operating on one engine to save on jet fuel till 3 hours later on cruising altitude and they then started the second engine. And finally the cabin was cooled. On a 7hour red eye flight this made it so uncomfortable and impossible to sleep.

My experience was great overall. Tanya was particularly friendly and helpful the entire trip. I was very pleased with her customer service skills. The plane was an older aircraft but the entire way was comfortable with barely any turbulence at all. Qantas should speed up its fleet renovation. Totally recommend using this airline.

Qantas is always subpar beyond comfy chairs for a domestic flight

I liked boarding the plane. The staff were rude, the food was appalling and the chairs the most uncomfortable I have ever experienced

an hour late, then had to disembark on back stairs and take 4 flights up to get to main airport. No warning, and difficulty for those with canes and poor knees.

Well my expórtenle with Qantas it wasn’t that good KLM from Bs Aires was delay Santiago Chile Qantas QF 028 was still in the airport but the crew didn’t opened the door for me soo I lost my fly And I stuck in the airport 13 hrs waiting for next fly by Latam Arline My question is can I have my money back for business class

It was ok, the additional baggage charges were a bit excessive given winter is a time for skiing. To have to pay $600 extra for skis was tantamount to robbery. Airlines should consider sporting goods as baggage. Likewise, they should consider increasing the number of bags allowed on international flights to known ski destinations.

Flight was canceled. I was not alerted. It was only kayak that alerted me

Flight was 2.5 hours late leaving. We spent 50 minutes of that sitting on the plane with no explanation. They did reduce the time in the air so we arrived a little less late which was something. The cheese and crackers were okay but the wine was terrible.

Couldn't access entertainment on app as said in an email
