Premium economy seats and food we're very nice although the price could be more affordable so we can do it more often.

Premium economy seats and food we're very nice although the price could be more affordable so we can do it more often.

mechanical issue, so delayed take-off (hence the low boarding rating) and made a number of people miss their connecting flight. Also took a long time to get our checked baggage. I luckily made mine with 5 minutes to spare, but it was nerve-racking.

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

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

A better selection of entertainment would have been nice. I found nothing that appealed to me as a middle-aged traveler. The flight attendants were gracious, helpful, and attentive. It also would have been nice to have more bathrooms as the flight was full and the plane was big.

Again, Air New Zealand was great. They kept bathrooms clean, food was actually very good, New Zealand wines a big hit

USB charging ports did not work on any of Air New Zealand flights

Liked the non-stop option, can always use more leg room!

Couldn’t request a vegan meal somehow but I noticed other people getting them

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.

Great food and good entertainment options for the long flight.

Good check in and helpful staff. Delayed for 1 hour. Took about 45 Mins to get baggage’s at DFW . Food was average ( Hindu meal ) . Overall it was good experience

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

We were upgraded and after just a short delay in attending to a safety check we were on our way. Would definately fly Qantas International on their Dreamliner again.

Good communication regarding any updates time of flight and flight delayed. The fight was delayed by two and half hours at eleventh hour. That was unexpected, especially when you international passenger.

The service was excellent. The quarters were a little cramped in Economy, and we had to exist there for 18 hours.

Don't irreparably damage my luggage, don't stand around talking in the kitchen area of the plane when a passenger is waiting to speak to you, don't run out of a meal selection so have me end up eating bread for dinner. Lastly, regarding the code-share flight from DFW to JFK....STOP PARTNERING WITH AMERICAN AIRLINES - THEY ARE THE WORST AIRLINE IN THE WORLD! The delay, followed by another delay, followed by disorganized boarding, followed by stale snacks fit for a rodent, followed by a pilot who literally slammed the plane onto the runway when landing causing quite some concern among the passengers.

Food was great. Customer Service not so much! Flight Delays.

BA Airbus A380 BC upstairs had 2 3 2 layout. The seat was comfy but access for those in middle or window seats had to climb over others fest to get to ailse when seats in bed mode. The layout was not nearly as private as other layouts. The staff was amazing as well as the food. Most airline food is average but this was restaurant quality.

Wonderful crew, good food. Absolutely loved the wine spritz and wish I could buy it!

There was no internet on the flight. As an executive flying during prime business hours, having internet is critical for a smooth experience. This impacted productivity and time that will need to be spent later to do the work I could have done on flight.

They took us all the way to Monterrey to tell us they United were not allowed to land and we were sent back to Houston. Terrible experience.

Great flight and crew. Need more legroom and DO NOT allow seats to recline.

I dont like to buy ticket type no carry on because I can have along with me my personal stuff like computer, headphones etc etc

Flight was very smooth from Boston. But when we got to Houston, the gate was not open and we waited on the runway for over 30 min!!

It was very good. the food was varied and tasty, the movie was the same, maybe I would recommend changing the movie selection every month because my flight to Amsterdam was in September and I came back from Munich en October they are flights so long and we need something to see. But however I liked flying with United

Flight attendants need to know their plane. Seated in first row yesterday. The seat had about a 1 inch recline that was not adjustable. I don't appreciate being awakened to raise a seat that can't go any further forward and such a small recline is either irrelevant or the plane needs to be repaired. Not the way to treat any customer and especially the ones who have paid that level of money for the seats.

Flights was great, service and transit support was outstanding - but the food was limited and of poor quality - only a snack on the first hour for 2 hours 1/2 leg. and a light breakfast on the second 4 hour leg.

typical but they have finally enhanced the wifi on some UA flights. Boy, its such a huge improvement

I like the first class seat amenities like the phone charger on the armrest even though it didnt really work on mine and the partition between the seats. I also liked that there were additional places to stash things during the flight. The food I got was steak and it was really tough to cut with the knife. Chewy too. A little disappointed in that. I liked that your name is on the screen too. nice touch. great service overall.

It was impossible for me to make the check in for Air Canada. Then it was very difficult to find the D gate in Houston airport . I hadn't have enough time to make it. Finding the gates in Houston it's so confusing. This was about my connection.

Multiple delays and gate changes resulting in arrival with a 5 hour delay.

The ground staff was so rude in Toronto airport ...very rude and did not answer simple questions, and made me look like a fool. Very rude ground staff.

As previously mentioned in last review , seats are small and uncomfortable, and baggage fees are high!

We got home a day late because of mechanical problems and that they wouldn’t put us on available other flights.

The seats have no leg room and my seat head rest was broken

Flights delayed over 4 hours with no compensation. No agents at counters to assist with re-booking.

Well organized check in and boarding. Aircraft had comfortable seats and lots of leg space, both ground staff and crew members were nice.

We culd not check in ovr the inrnt since e did not have the unied airlns boing efence Tis is alays a issue when boing coe shae flits witstr allince

The flight was good they didn’t take off on schedule

Hey as long as you bring me back to earth in one piece I’m good! Otherwise great flight smooth take off and landing good staff Only thing is the staff at the back of the aircraft chatters a lot it’s annoying at times but I’ll let that go because they are very sweet overall.

Flight was good, little delayed because of busy plane traffic

The plane was comfortable but the crew wasn’t friendly.

The plane was very creaky and lots of ringing. Plane was dirty and dingy. I couldn't hear the captain's announcements from the flight deck. Not sure if it was the captain or the audio equipment, but good thing there wasn't an emergency where we needed clear instructions. The overhead compartments were clearly full, but the flight crew allowed people to stand in the back with their carry on luggage. Then after everyone boarded, they had to go to the front to gate check their luggage because there was no room for their bags and then they returned to their seats...such a waste of time when clearly the overhead compartments were full when they originally boarded.

Delayed 24 hours. Should have called it much earlier They provided quality accommodations, food vouchers etc. FINALLY The issues started at 8 AM and they cancelled the flight at 11:30 PM, with no plans for a new flight.

I booked an aisle seat and was given a middle. At 6'4" 230lbs, it is not ideal to fly in the middle row for myself and passengers.

Awful. We had an 8 hour mechanical delay- no vouchers and no kind/courtesy/professional representatives in the entire airport. Not only was it a terrible experience for both my 7 year old and myself, I still have not heard back from American about how they’re going to correct it- I’ve sent 2 or 3 emails about our experience- which was just awful. Not to mention according to national traveling laws, we should be reimbursed… but of course they’re not responding.

Overall it was good but not great. The aircraft was an old and seats didn’t recline in business class unless you kept playing around with it.

The plane was subbed for another last minute, the gate was changed last minute. Could live with that but we boarded and there was a delay which totaled an hour in the end. There was a technical issue which meant wheels needed to remain out for ten mins after take off. My USB phone charger was broken as was the headphone jack which meant I could t enjoy the IFE and could use my phone after a few hours. Even the map function on the plane failed to work after a few hours.

The flight was delayed and we were told the airplane is on its way to the gate from the hangar. We were told this for 2 hours and the flight was continually delayed in ~30 minute increments. Then we ended up having a new airplane. The issue wasn’t clearly communicated and it left everyone feeling confused about when we would actually be leaving. Whenever they communicated a new boarding time it felt arbitrary and random. The boarding process was a mess and disorganized, which made it last longer than necessary. Landing was rough. Seats were uncomfortable.
