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

Excellent as always, I won't fly to Australia, and back to the US on any other airline. The flight crew is always top notch, and have a way to make one feel extra special. Thank you for your service, I would rate Qantas Airways a 10+.

After already paying for excess luggage prior to flight, i was advised AT check in that i had to pay $816 or forfeit my flight! The lady at the counter was SO rude and had already started offboarding me when i said i would pay it after asking her three times for the exact amount! Have lodged a formal complaint yet heard nothing. Will not ever travel via Qantas again

We got delayed three hours and nobody thought to have the bathroom fixed while we were sitting waiting to board? took a full hour to have maintenance come and check it off. Had to shut the bathroom down twice so that the pilots could go to the bathroom. Everyone missed their connections.

Flight left on time and we arrived 25 minutes early! There was a gate available when we arrived so early on a busy Sunday afternoon! Flight attendants came around twice with the drinks cart.

Wonderful. Quick boarding. Early departure and we arrived 30 minutes early at our destination. Unfortunately, when you arrive early, there is still a departing aircraft at our gate. We had to park for 30 minutes until the gate was clear. So our early arrival was not really early at the gate. Otherwise it was a quick and smooth flight. Appreciated the efficiency.

Flight on time. Excellent service in Premium Economy. Great food served and cleaned up promptly. Unfortunately the climate control was malfunctioning and it was very cold and felt a bit like camping. Cold helps with sleep though so not complaining too much. Slept well. It asks to rate "entertainment". I do not like any IFE, don't shove a big screen in my face—I have my own phone if I want it. So this will always get low ratings.

We had turbulence ever 1/2 hr or so and the captains announcements were SOOOO LOUD

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

Overall we had a good experience during our flight from San Francisco to Houston.

Airport terminal was outdated, flight was on a small jet with no wifi

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.
