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.

Qantas is always subpar beyond comfy chairs for a domestic flight

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

I was promised by United Airline (operated by ANA) that I will be seated together with my kids as I am the only adult flying with two minors. We did not get seats together in our 11 hours flight from LA to Tokyo. When asked at the gate, ANA representative said United Airline should have informed them that there is a parent flying with two minors. He said they can’t do anything in the system as the flight is full. He ask me to ask passengers next to me and the kids if they are willing to change seats. This is ridiculous! However, I went in the flight and asked other passages but no one willing to change seats. 11 hours and we were seating separately. I was very disappointed with this. It made things super inconvenient for me.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

Flight cancelled instead of leaving Friday am now, maybe, leaving Sunday

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

Service was professional and quick. Premium economy seat was comfortable given the class

one of the flight attendants on the Dallas to frankfurt leg was somewhat rude..

I'm a United 1K member and have ben for 10 years. The gate agent had no control over the boarding process and had us passengers queued for hours as delays were announced. On the plane, the overhead air nozzle was broken so col over was powering through on me and the passenger next to me. Not a great experience for a million miler on United. Feel free to contact me.

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

Flight was overbooked and seats assigned to multiple passengers. Delay 1 hour to sort out.

Good but I don’t received my bags yet is been 5days still no update

It was pretty straight forward, no glitches or hidden costs

It was a short flight so, everything went smoothly and we got to where we needed to be safely.

Didn’t make it on the flight. Delayed then had to be rebooked, which in turn had me waiting at the airport for another 8 hours before next flight

No TV on the flight. The charging outlet was not working. No food, even a sandwich. The served orange was poor quality.

Selected seats 5 months prior to date. Had email confirmation and seats were not honoured. Family did not sit together

Loved and was pleasantly surprised by the food!! Request Lufthansa to help transiting passengers at Munich (confusion whether to go thru passport control or not).

The flight was comfortable and the staff were helpful and friendly. However, we did not know we were flying PAL until we arrived in Canada, so it was a bit disconcerting. In addition, which port we were leaving from was confusing.

They did not let us board because one member needed a transit visa, which was not evident at the time of ticket purchase.
