I never flew with alliance. Kayak is a joke and none of the flights or times were correct. Won’t ever use kayak again

I missed my flight due to unforeseen circumstances It was, however , an excellent price !

We had a medical emergency, needing to get to an emergency room upon landing at LAX. I let the back flight attendants know the situation. One, David, contacted the pilot, who made arrangements for EMT's to be there when we got off the plane. They went above and beyond for us. We didn't have to go through customs, as a customs person came to us and checked us right at the exit of the jet way. Another wonderful woman, a United employee at LAX, perhaps a customer service liaison, took care of our luggage situation, as we weren't going to make our connection to Bozeman. When we came back to LAX to see when we could get a flight to Bozeman, the personnel are very accommodating and booked us on the next flight out, and assigned good seats. It was a horrible flight, physically, from Sydney to LAX, , but the professionalism of all involved was excellent! We are very grateful fir the way they all stepped in and helped during a very unpleasant medical situation. Thank you!!

PREMIUM ECONOMY - excellent !Brilliant new plane. Excellent tv catalogue. Good food. Good communication and service from all friend Australian crew. Good communication from captain. Best travel experience in years.

Very good overall. However, your choices of free movies was limited and there was no music Channel???

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.

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.

Flights were on time actually early service was good and crew cheerful

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.

Flights were on time. Free Wifi on plane. Everything was well organized.

Experience was great - no complaints. Took off on time, landed early. Got to the gate relatively quickly - took a little bit of extra time to deplane but nothing excessive.

Economy plus was so cramped I could not use my laptop. It was beyond bad.

United is one airline which regardless of how many separate United tickets in existence, if one flight breaks down, the airline will take care of all the flights.

Everything was on time and service on the flight was great!

Wifi Bluetooth features for watching in flight movie was horrible. Screen kept blacking out no connection of sound although it said connected. Other than that smooth trip .

The travel company that you have on your site did me so wrong. I don’t know how it happened, but they put my son‘s name on my plane ticket flying to Vietnam. Along with his birthday. They would not have let me fly from Fort Myers to Ho Chi Minh City. I don’t think that I can ever use your service again. I typed my information into the browser along with my passport number and four days before I’m leaving I have to quickly search another ticket to fly out here.

Plane outlets in my row not working to charge phone. Staff response was, well it should be. Plug into seed for volume not working well. Had to find the sweet spot for plug in or it would shut off and on.

For a 4 1/2 hour international flight all we got was 1 small pack of cookies and a drink. You had to watch movies on your own devise.

The seats need better cushioning for a nearly 5-hour flight, it was a bit uncomfortable. I'm glad American has free wi-fi but there were was a bout 30 minutes in the middle of the flight when there was no connection which was frustrating.

My original flight got delayed day of so I had to rebook it from one layover to two layovers. The flight also left earlier which was a slight inconvenience but manageable. Then my first connection flight got delayed 3 separate times for a total of 2 hours delayed, causing me to miss my second connection flight back to Santa Barbara. Now, because of this missed flight, I am missing my college classes that I pay for.

Flight: Started on time. Comfortable flight. Arrived on time. Crew: Very cordial and helpful. Drinks and snack was served with a smile. Overall enjoyed the trip. Regards, Hari Doss Chanchala Doss

I’m sure Business Class would be excellent. I feel like I got what I paid for. Overall it was good and well worth it. I would do it again.

This short sector between Miami and JFK was undertaken purely for business purposes, with efficiency as the primary objective rather than a full inflight experience. Overall, the journey met its intended purpose; however, the ground experience at Miami stood out significantly. During check-in, I was unable to link my frequent flyer details from Qatar Airways (oneworld alliance) through either the self-service kiosk or web check-in. The situation was handled exceptionally well by the check-in agent, who demonstrated remarkable ownership. She coordinated across multiple counters, ensured my frequent flyer number was correctly reflected, reissued the boarding pass, and confirmed that mileage accrual would be recognized. Additionally, she ensured the boarding pass reflected priority status, enabling a seamless priority check-in experience without delays. This level of proactive service was both commendable and impactful. Boarding and the inflight experience, operated by American Airlines under a codeshare arrangement, were efficient but largely transactional. While operational delivery was smooth, there was no visible recognition of oneworld frequent flyer status onboard. In comparison to the consistently personalized engagement typically experienced with Qatar Airways, this absence was noticeable—though understandably a potential limitation of codeshare alignment rather than a direct service shortfall. In summary, while the flight itself fulfilled its operational intent, the exceptional professionalism and commitment demonstrated at the Miami check-in counter was the defining highlight of this journey. Greater consistency in elite recognition across partner airlines would further enhance the overall experience.

Business class was very good, one of my best flights

Incredibly delayed. First delay was due to plane coming in being late. Resulted in 30 minute delay. Boarded and then had multiple mechanical issues. Was on plane for an hour until they told people they could get off if they wanted but couldn't come back. Then gate agent rushed in and said they had lost control of who went off and we would all have to deplane and then get back on. They said flight had not been cancelled. Then while sitting waiting to board again they announced it would take two hours to get new plane and to wait at new gate. New plane arrived, reboarded only to find out that pilots had timed out. Waited for new pilots. In that time one of the flight attendants timed out. Never received food or water while waiting. Was confusing mess as to what was happening. Even flight attendants and gate agents were getting frustrated. Almost 6 hours delayed. Called American to received flight credit but can't get anywhere as Kayak reservation and don't have a ticket number. Reached out to Kayak but never heard back.

The new planes (American Eagle) are beautiful and especially comfortable. The flight attendants are consistently professional and courteous. And, while it may seem inconsequential, the new liquid tube of coffee creamer—in contrast to the powdered coffee creamer—makes all the difference in a cup of coffee.

Flight was delayed and they gave up my seat on my connection, even when I could still make the flight
