Great airline service by the staff. I highly recommend it

Time to upgrade those planes so you can provide first class.

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.

This flight was the second leg of a trip that began in Auckland, New Zealand. I was unable to find a way to select seats in advance. The boarding passes we were given in Auckland did not have seat assignments for the second flight. There was no way to check on it until personnel showed up at the gate in Los Angeles, immediately before boarding time. The flight was overbooked by one, and since I was traveling with my sister, we needed two seats. We waited in considerable anxiety for everyone else to board and when one person did not show up, we had to take whatever was left. At least we finally got on the flight although we were the very last to board. We were not able to sit together, of course.

We had difficulty checking in as United didn’t recognize the confirmation number and the agent was not helpful. We went to the United Assistance desk where the agent was able to process our reservation. We also weren’t allowed to choose seats in advance.

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

The food was not as good as Air New Zealand. The veg pasta was pass-able but the veg cibotta sandwich was dry, hard and not up to par. The coach staff were attentive and accommodating.

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.

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

Staff on the flight were terse, bossy, and impatient with people on the plane.

The crew was excellent. We brought our own snacks due to dietary requirements and personal preference. There was an ample beverage selection. The seating was comfortable enough. My only complaint was that there was no announcement, or at least none that we could hear, that our connecting flight was departing from a different terminal. That could been announced by the air crew in flight or before disembarking.

Although delayed an hour, the gate attendants kept us notified and the rest of the trip went off with no issues.

We showed up to our gate less than 15 minutes after boarding started and they wouldn’t let us in. It was still 15 minutes even before take off so we’re weren’t even late to the flight.

When I checked in with full service, requesting a wheelchair, as I had asked for ahead of time, the customer service agent said “wait over there, nothing more. I waited in the designated space for about 40 minutes before learning from another passenger that I needed to check in again at a specific assistance desk. I was early, so I made it on time to my flight. Your agent should not assume I knew anything, which I didn’t. This was all new, in a recently remodeled space. New to me, anyway.

Great trip. No complaints. Impressed with the crew’s response to various challenges pre-boarding.

We were 35 minutes late because the caterer had not stocked the plane. Plane was fully loaded and ready to go 15 minutes before departure time. We sat there 35 minutes?

The seats are too small/crowded. It is frustrating to be forced to sit with someone who is overweight as they crown the other seat. Nothing against the person…just the airline companies who continue(over decades!)to reduce seat sizes. Americans are fat. Those of us who are not are tired of being compromised by the airline companies who don’t faces that fact and make adjustments. Maybe have “overweight seats”? Maybe give us a discount for being forced into an uncomfortable flight due to others overweightness? Please, make adjustments…be accountable. Thanks!

I flew standby with my two children and completely forgot it was Memorial Day weekend. We tried to fly from PDX to YVR. Unfortunately, after four attempts, we gave up and tried SEA instead after the holiday. The ground crew was very helpful, checking us in and accommodating us when we were finally able to get on a flight. The sad part was that they accidentally loaded one of my suitcases on the Vancouver flight without us during one of our attempts to get on a flight, even though it had a standby tag on it. I filed a report with baggage services, and thankfully, it was returned to PDX the following day. AS was in touch with us and updated us on the process of returning the luggage to the USA.

Internet was great. It was nice to watch a movie. The crew was very nice.

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.

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.

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

On the Qantas flight, I could barely hear some of the announcements. It was better when I could read 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

Flight arrived late with no one to help over 30 people rebook. I slept at the airport.

I'd like to see AA's flight safety record clearly and prominently posted online.

I was in premium economy. My seat didn’t recline much - it was broken. My phone charger didn’t work.

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

Poor seating comfort, seat cushion too thin, very uncomfortable. My luggage didi not make the flight due to equipment change. At least. United had it delivered the next day. I was without my toilet items for one day.

Flight cancelled because of the grounded 737s. United was good about it and got us onto a later Alaska Airlines flight to Oakland (not San Francisco as originally intended). Had to go through security again and my wife dropped her MacBook Pro, which broke, a $2,500 whoopsie. But we made it home.

I liked being upgraded to first class. The flight was a redeye, so I did sleep most of it.

It was pretty straight forward, no glitches or hidden costs

The whole plane smelled and felt old. The seats were very uncomfortable. Multiple delays. Extra fees.

For goodness sake, board from the back of the plane to the front and assign overhead space. It would fix everything. Seriously.

Aircraft had technical issues. After 3 hours of trying to resolve, flight was cancelled. Was booked on a flight leaving 12 hours after intended departure. Now on 4 flights instead of 2 and a day late to my destination.

PDX staff was great and we arrived on time in YVR.

Horrible I had a health emergency and couldn’t go Air Canada refused to allow me to reschedule

Really poor travel experience. My first flight was cancelled, which cut my international trip short and threw off my schedule. I will not be flying Air Canada again if I can so help it. The crew and in-flight experience was pleasant and enjoyable but the consistent delays and cancellations are not worth it.

Economy middle seat was so narrow that I could not sit back comfortably with passengers on either side of me. Over the 9-hour flight, with my body slightly twisted most of that time, my previously-healthy left knee became very painful, even though I got up to walk multiple times. The knee is still painful 3 weeks later. Otherwise, it was a nice flight, but I was crippled over my entire vacation.

The staff were condescending and withheld at times. There were times when they appeared to be more concerned with socializing with each other than appearing professional. I know it must be a hard job, but being chatty and handsy with each other in the public view only to be condescending to customers isn’t a good look.

No entertainment what’s so ever so you may want to prepare yourself. Our flight was delayed.
