Very quick flight so no time for refreshments. We took off. Then landed. The end. Seats were too tight. Very cramped Grateful for the short flight cos moving around wasn’t possible

Please add more Bollywood movies and recent movies to the entertainment.

I was not even on that flight and did not even book a ticket. Kayak did a phenomenal job

The disembarking steps in Wellington were precarious and I felt quite insecure. There was no one on the tarmac to greet us and help. The embarking ramp in Blenheim was much more satisfactory. The rest of the flight was fine.

Entertainment screen froze and had to be reset. Noticed it happened to other passengers as well.

Flight was delayed by 2 hours. Got lucky that i had a long connection, else would have certainly missed my connecting flight. Food is just okay, specially the breakfast is worse . Asked for water 30 mins before landing, the response is that we are landing so everything is packed . I guess traveling in economy that’s what we get. Probably business class passengers would get a different answer. Only good thing is that wifi service is available from auckland to lax for most part Next time will try united or American and then compare.

I was trying to get confirmation on if my luggage was going to be moved to the earlier flight (I requested standby to get home earlier) and was unable to get help from those working at the counter. The request to be moved to an earlier flight was handled smoothly through the app and appreciate the ease of the request.

Do the bumpy weather the whole trip they were very few times when the seatbelt sign wasn't on

Great except paying $240 usd for 2 pounds over on a checked luggage. Outrageous.

Kayak did not propagate my United miles account and I had to manually get credit.

Our 6.30am flight was boarded then cancelled to fly at 10.55am . We were flying to Brisbane to attend a funeral at 12 noon an hour away . This means missing the funeral due to unreliability of Virgin . Unimpressed !!

It was with Link Airways and the Saab 340 jet was noisy and little comfort.

They didn’t sent my luggage I got it 24 hours later

Plane was late and they wouldn’t check our bags through to Tokyo

Overall experience was good but what really impressed me the most was the care the flight attendants took of a sick passenger who was sitting in front of me. The flight attendants would come and check on her quite regularly providing her support and comfort. Brilliant service!

Only answered OK and poor as there was no entertainment and I didnt have any food

4.5 hr international flight. We got a glass of water. Ranks up there with Ryan Air, Easy Jet, Spirit and Frontier. Expected better.

Gluten free options less explicit on business class, but great service

Very good… seems the virgin staff particularly in the lounge and in flight exceeded expectations.

I liked everything about the experience but would have liked some free snacks!

Hard to move and get out of my seat when the passenger in front is in recline position.

It was a good flight and no complaints. It just wasn't anything that was better than any other flight.

The crew were wonderful - if only the customers were as well behaved as the attendants!! Ha ha! If you could just talk to God and ask for less turbulence next time.... Juuuuust kidding....

Basic airline, aircraft and service. AA gets you from point A to B. My flight was delayed by 2 hours too.

No internet on flight, which makes log travels really hard.

My flight from Dallas to Sydney was cancelled. My entire trip was rerouted to include the following: Hartford to Washington DC Washington DC to JFK JFK to Auckland Auckland to Christchurch I paid for an aisle seat on the flight to Auckland and was asked if I would take a window seat to accommodate a family. The agent at the podium failed to mention that the family had a 3 month old baby and that a bassinet would be used during the 16 hour flight. The only way I could get out of my seat was to crawl under the bassinet of the sleeping baby. I think it is wrong that I was no given the choice to sit in another seat, that the agent knew what she was doing and chose to not properly disclose my seating arrangement. Terrible treatment.

they ran out of fruit for breakfast and so I just had a yogurt instead. other than that the flight was good

by the time they got to our row, they were out of some of the food options. games and movies were great but maybe more game options like tetris or pac man would be great

Great as usual, some delays but well communicated and made up for in the air

Poor! This flight was delayed 14 hours. There was no assistance in helping customers find other routes to their destination, nor any other kind of support. It was a chaotic experience. I'm not likely to fly with AA going forward.

Delayed, toilets did not flush, pilot parked to far away from Gate

It was good but only meal served is very less. Meantime good to add rice and chicken in one of meal

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

In Liberia airport 5 min before our departure the airport was closed for takeoff for 30 min. Upon arrival to IAH we didn’t have any available gate and waited taxing another 40 min. As a result we arrived for 1+ h later. The walkway to the passport control in IAH is about 1-2 ml long. After the passport control you have to pass the security check again. Only 3 out of 16 checkpoints were open and the line was enormously long. As a result, even though we supposed to have 2.5 hrs gap in between the flights we missed our transfer. United rebooked us for the next available flight early morning and provided free hotel and meal vouchers through.

United is an incompetent airline. They parked the plane on the tarmac for an hour after arriving because they “didn’t have a gate available” it was actually some sort of lie because as we de planed there were approximately 9 open and manned and empty gates that we walked past. Many people on the flight missed connections for the hour long sit on the tarmac. Utterly baffling and incompetent behavior from United flight ops.

I boarded flight UA#1318 at Sacramento International Airport going back to Houston TX. The flight was scheduled at 5:10am. I was able to check in virtually using the United Airlines app. When I entered the airport, there was no one outside assisting with checked bags as it was for Delta Airlines. Immediately upon entering, there was a LONG, EXTREMELY LONG line to the kiosks to get boarding passes. I stand in line to get boarding passes then had to move to ANOTHER EXTREMELY LONG line to get my bags checked in. While standing in this line, we noticed an agent taking customers to 3 at a time to her station to check their bags in. Lucky for me, she called me back, checked my bags for me and I was on my way. I then encountered another long line at the TSA check and to avoid I ending up having to sign up for CLEAR to bypass it. So glad, I did.,...Both of my flights were great with no issues, butthe check in progress at Bush Airport was so much smoother. Check-in at SMF airport needs to be anaylzed and corrected. Do better United, I know you can....thanks

everything was pretty good. Houston airport is awful. Unnecessarily inefficient; people working there are rude. Badly run

Staff on board was excellent. Positive upbeat helpful- like it used to be.

The Sears in the 800s are not too good perfect Airbus why cant the new 737 fix that

Air Canada’s problems are not staff related by and large, no. The problem is tiny jets between the U.S. and Canada - yes, believe it or not they are still “international” (just ask our own Mango Maniac in power in the U.S.). The little aisle is compounded by a design flaw of a “dog leg” starting at seat 12. Woe be unto you if you sit here as passengers and attendants do not have sufficient room to not hit you in the face with backpacks. One thing I will say very positively about Air Canada is you still provide pillows and blankets on transcontinental flights to all, not just the elites. Your tiny improperly designed jets are also a problem flying city to city within Canada also. One can only say you remind us of a “Jet Blue” or “Spirit” experience. Also your luggage space is downright Byzantine! We will endeavor to avoid you and use other U.S. carriers, albeit charging more.

Terrible canceled flight and lost my luggage. Flew me to Halifax. Tgat flight was delayed, had to spend night in airport chair.

Better entertainment & food options more may be adding chicken option or on vegetarian side good quality pasta

My seat was not comfortable. Flight was smooth. Regretfully we had two delays before takeoff

Amazing service, with enthusiastic crew members, and some breathtaking views of Vancouver. No IFE though, as it is only a 1 hour flight on a regional Turboprop jet.

They are very proactive and made our boarding easy and always notified us about any changes well in advance.

My seat was covered in vomit and I will be reaching out to Air Canada

It's kindof ridiculous that your system is even asking me about this since my flight was canceled and I wasn't rescheduled.

3 hr delay at the gate while they were doing maintenance. Next time, do not board passengers while maintenance is being performed

Digital check in is very poor with air canada compaired to other airlines
