I couldn't hear all of the announcements. It was nice when they put them on the screen.

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.

The boarding timing needs to be improved. The flight was delayed again because it took way too long to board. I was already exhausted from sleeping at the airport and spending all day there due to delay from my previous flight that connected in Chicago.

I had a terrible experience. My flight got delayed from Atlanta to Chicago on Monday April 6, 2026, and that led to me missing my next flight to Brussels. United Airlines didn’t provide me with any accommodation for shelter. I had to sleep at the airport in Chicago. The next flight I was put on didn’t leave until the evening hours of Tuesday 4/7/2026.

Boarding was again a "free for all". We were boarding group 4, and almost the entire plane was able to board before us. It's a shame that someone who follows the rules, gets the short end of the stick. Not fair.

Flight left on time, arrived early, pleasant staff provided water, coffee, etc. access to bathrooms was reasonable and were well maintained. blankets were available, lots of entertainment options. LUGGAGE SERVICE WAS GREAT. I got my one checked bag quickly and was able to make a bus connection for a 2 hour bus ride saving me from waiting another 1.5 hours.

The boarding process was straightforward. One pertinent observation regarding all boarding procedures is that if an individual requires assistance or possesses a special status and is part of preboarding, it is advisable to limit the number of passengers who can preboard with them, rather than the entire, sometimes large, companion groups. The seats are uncomfortable, and the entertainment options are significantly inferior compared to other airlines. During the snack service, I requested an additional bag of snacks, but my request was denied. Initially, the flight attendant agreed to my request.becoming a strange accurate moment. The flight duration was four hours.

The flight was officially delayed 3 times, and was actually later than that. Combined, it was a 3 hour delay, but there was no recognition (miles, voucher, etc). The crew seemed stressed. The captain sounded nervous in his announcements. The flight itself was smooth and uneventful.

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

Great until we got to FRA. The next trip leg we were put in Business Class where seats had minimal padding!!!! They were awful and United Airlines needs to have their Lufthansa partner up their game or I won’t fly with them again!!

I had a good time. However, I paid for the wifi and it was in and out the whole flight.

one staffer was frustrated (it happen); the flight was late and the pilot mentioned they'll make amend but the snacks were the same, other than that the aircraft was clean and everything went smooth, no complaints

Plane was super cold. No entertainment unless you were with mileage program Getting off the plane was super slow

I appreciate that I finally got the seat I paid extra for this time. Thank you

Half of the TSA checkpoints at PHL are closed. Also, there is no standby for first class passengers. You can only standby for coach. Very dated policy and inconsistent with peers.

It would have been nice if American tried to care.

Delayed initially because they couldn’t print the flight details. Poor instruction on delay. When I got on the plane the flight attendant argued with me about whether my carry on would fit (it did, although she didn’t acknowledge that). No greeting (other than arguing with me) getting on or off the plane.

Beverage service was not good. Also just one service in 5 hr 30 min flight. No ask fir water ir anything beside one time beverage service.

They are always late and seats was also not having working charger

Broke my luggage and I can't get a resolution yet.

My flight to London from Philadelphia was cancelled due to weather.

Pilot navigated severe weather/snow storm with skill. Described his intentions clearly
