I like Air NZ, but rather old plane seating in Premium Economy. Not very comfortable , nor very roomy.

I like Air NZ, but rather old plane seating in Premium Economy. Not very comfortable , nor very roomy.

Needed more leg room. Leg rest and entertainment system box took up a lot of space and I'm not tall. Breakfast was good. Poor quality of the entertainment options.

My experience with Underpricer was not great. The representative assigned to me did not tell me beforehand that selecting seats, which i could not do through ANZ, WOULD ADD SIGNIFICANT cost to my ticket (all flight segments were reg economy seats. The seat selections for the ticket, MCI-AKL, AKL-PER, PER-MCI, cost $284 USD. I WAS NOT TOLD AHEAD OF SELECTING SEATS chosen by the rep OF THE COSTS and never received an itemized invoice of the seat selections.). The costs of seat selection, an option solicited as a service, with no mention of costs, should have been disclosed to me prior to seat selection and certaily should have been itemized. For all I know, the $284 was not referred from the airline but made up and taken directly by Underpricer. Next, when i checked in, united couldnt find my ticket. This is probably why i didnt get a seat selection on that flight and couldnt check in online, despite Underpricer prompts to do so a week before departure, or at the kiosk at the airport. I had to wait for special help at the counter, then was told that because the flight segment, MCI-IAH, operated by United Airlines via the ANZ. ticket, had changed schedule slightly since I BOOKED MY FLIGHT, the MCI-IAH segment had been decoupled from the rest of the ticket because the IAH layover was now 12.5 hrs AND DID NOT QUALIFY AS A THROUGH FLIGHT TO AKL.. This meant my checked bag could not be checked through to AKL and id have to pick it up at IAH, THEN WAIT MOST OF the long layover WITH the large checked bag until ANZ counter in IAH OPENED for checkING just prior to the flight. Apparently, although underpricer had notified me of schedule changes, they did not update the ANZ TICKET, leading to this problem. Finallly, although I RECHECKED TH BAG IN At IAH 3.5-4 hours before the scheduled departure and the IAH-AKL segment was a direct flight, ANZ LOST MY bag and it took 4 days to find it and get it to me. Not fun.

The flight was smooth and on time. Entertainment options were lacking and there was no food, other than some very boring snacks.

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

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.

Aircon set too high so VERY warm and VERY uncomfortable.

Full flight. Flight attendants were harried. Otherwise, fine for the typical cramped seating conditions in coach.

Great! Flight was delayed by 30 mins but all was great. Thanks.

The recline on the seat in front of me came back so that I was staring at the top of the man’s head in front of me the whole trip. He refused to bring his seat back up twice every time he was instructed to do so and only relented when he had a tray of good in front of him. And then right back in my lap!!! Horrible man!! I complained to the staff multiple times, but no one would address the issue. Otherwise, it would have been a perfect flight.

On time, quick boarding, so nice of them to honor active and retired military with early boarding. Attendants were nice . Plane was clean. A bit crowded like all flights.

Everything was great except the fact that catering did not restock the flight from ATL to GRB and we were only offered water.

The WiFi on the plane was out. I also thought movie options were lacking.

These Delta 717 jets are ancient. No entertainment and you have to pay for WiFi that barely works and goes in and out the whole flight. Delta should be ashamed flying this garbage.

My seat was changed without my consent. It wasn’t a major deal but annoying.

Everything went smooth from check in, thru TSA, then boarding, and a smooth flight to ATL.

Flight was 2 hr. delay, making me miss my connection to my final flight home to Roanoke. Now 12:38am in the morning and I just got the first available ticket at 5:30 pm tomorrow evening. Sleeping in the airport.

bulkhead seat had very little legroom - even in bsiness class.

I didn't take this flight. I changed the flight. Why am I getting surveys and notifications on flights that I change. Seems like a defect with Kayak.

I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️

Despite having numerous passengers held up by American Airlines delays. Qantas (an AA partner) closed boarding with 0 flexibility

Boarding , crew and meals were all amazing. Couldn't wish for a better LOOONG flight from Dallas to Sydney .

Boarding was effortless, the food was outstanding, the seats in Premium Economy were extremely comfortable, and the staff and crew were excellent.

We had a cancellation due to weather, but the American Airlines staff was very helpful. Once we got on a plane, the trip was great.

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

Our boarding and flight was very good. However when we landed and pulled in to the gate it took 55 minutes for the jet bridge to be positioned next to the aircraft. That caused us to miss our ground transportation and it caused us unnecessary last minute transit planning and expense. Our flight was AA1733 on March 17, 2026

I liked boarding the plane. The staff were rude, the food was appalling and the chairs the most uncomfortable I have ever experienced

One of the best Qantas business flights I've had. Quality product

Much better than I expected for such a long flight.

It was nice having space in the way back where it thinned out with passengers, most folks in the far back were able to lay down and sleep. That was a pleasant surprise. Made the 15 hr flight go by pretty smooth, watching a few movies and resting. I had previously never used an airplane toilet, but finally used one. It wasn't too bad. All workers were very helpful and friendly. Their hospitality was welcomed as well

It was great. I really love the app. User friendly and very comprehensive when it comes to having information at my fingertips tips related my travel.

Seat would not recline, and charger did not work. Person in front of me reclined before we took off and left it reclined when they got off the plane. Nobody ever told them to put their seat in upright position....which meant I was somewhat trapped in my window seat when deplaning. Another passenger had to go to their seat and un-recline so I could get out.

- delayed because video screens not working - delayed getting a gate at DCA Just continued bad experience IAH to DCA.

I couldn’t give an honest evaluation, because the Houston airport has a problem and I was stand up for several hours and after a long trip from Munich I feel really very tired

The experience was good overall; however, my United Airlines Mileage Plus Account didn't reflect my flights to Houston from Newark. In essence, my mileage rewards points do not reflect my actual travel. This should be corrected.

Good flight, even though there was a delay, still got back on time

First class flight crew was barely available. They came through 3 times while we were on the plane for nearly 4 hours.

It was partially ok .. not anything like from Orlando to Houston... first the flight attendant was not so nice and insisted on have a small backpack down when really was not to put in danger anyone, also the beverages they were not so good... not big chance to select other tea.. the seat was partially ok could not have those flips to hold your head.. and finally when it land off in Guadalajara, it was raining and the flight was going to the main area then go back and drop us out of nowhere with the rain.

Really old place. Not as clean as it should be, tray tables needed better cleaning. The items, trays and some other items need to b6 engineered. Anything task you or crew may do is incredibly load, seriously engineer for quiet smooth, easy. Just opening and closing the tray table is actually dangerous and can easily injure a finger. I'm sure it happens as it happened to me! First time I used United and likely will be the last!

Got automatically assigned a middle seat, unless I fork out extra money for seat assigment.

There should be a visible sign of Air Canada, because I walked all around and I didn't notice where was the desk, I was in a rush for the time because it was very difficult for me to find the D gate.

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

I was forcefully re-routed to another destination and was delayed a total of 8hours. I have still not received my bags, no one is taking responsibility. The agents at the airport lied to me that I will get to my destination same time as my previous flight where I was forcefully re-routed from.

Flight was fine. Arrived on time. More room in the seats would be nice, but not something that is likely to happen.

Overall very positive. First time flying Air Canada. Only 50 minutes for transfer in Montreal. Made my gate only because I ran the whole way for my international travel. Told I would make boarding when I checkedin in Houston. If I was older I would have missed my flight.

The food was horrible the flying attendance hardly made any checks and the seats were very tied ..

last minute was rebooked. This rebooking made me miss my connection, added a stop in my itinerary without my approval, and had me arriving 10 hours later to my destination...for a delay that was 2 hours. To boot, my final flight from London to Athens booked me in a middle seat, where I originally booked all aisle seats. This was incredibly uncomfortable for a 24 hour journey and made me incredibly upset.

They changed our seats on us and ended up giving us the last row in Business class. We added wheel chair service and did not get it at any of the airports. My mom had to walk everywhere which was just unbelievable that they didn't provide this service. Just terrible

It was fine, everything on time! Tired of having to pay for all the extras?

First time flew with Air Canada and my Last. Really bad food that too in a business class. Waste of my money.
