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.

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.

Air conditioning was turned to the wrong setting. Way too hot. The entertainment system kept resetting and didn’t work half the flight. Said something to the crew. They didn’t do anything to help. Plane had a mechanical problem that resulted in 2.5 hour delay. Boarded the plane, had to disembark and get back on.

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.

Good and appreciate the effort Air Zealand puts into using more environmentally friendly food containers and utensils. yay! One of the better airlines for this for sure. Still some bad stuff, but at least Air NZ is trying. :) Also really enjoyed the bluetooth option for personal headsets. :)

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.

Great entertainment options on the screen. uSB A and C chargers. Free WiFi! Crew were excellent.

Service was excellent and they’re very helpful and nice

Check in crew member was very helpful, nice and excellent service👍

No lunch on a x-country flight scheduled for 10:50 am departure, arrived 5+ hrs later. That requires a black box label before you pay for the tickets. Worst, when I checked in online, it's specifically said that lunch was served on his flight for economy Plus passengers.

The crew took good care of us. The flight from ATL to SFO is a longer one, and there were multiple beverage offerings. I like the 757's that Delta uses. Good airplane that is comfortable. I do wish Delta would separate Priority boarding from the better seats. I would gladly take a smaller seat in an open row than be jammed into Comfort just to get priority boarding, just to make sure I don't have to check a bag.

This was our second flight using the Delta One class of service. Overall, it’s a good product but for me the POD configuration is a bit constrictive. I am an average size male at 5’ 10” height weighing 190 lbs so it’s not a size thing for me. I’d rather have extra wide seats without the POD walls to be honest.

The airport was reasonably clean. The boarding process reasonably efficient. The cabin crew was efficient, polite but not that friendly. The food quality was unremarkable and the choices were awful . There was either a so so chicken dish or a “ vegetarian “ option which was really cheap carbohydrates drowned in cheese. Signing onto i flight wifi was not straightforward. Overall it was a very average experience

Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

Nothing special. The crew never went out of their way for anything.

The flight crew was friendly. I tried to adjust my seat online ahead of time but no option existed without additional fees. My friend asked at the gate about a seat change and was able to make it happen. That was great! The flight crew moved a very tall gentleman and his companion which allowed us to have more space which was nice. Overall, good experience. Appreciated the blanket and pillow.

I liked the friendliness of the staff. The cleanliness of all 3 planes.

It was beautiful easy and smooth experience. Thank you. Will definitely get Delta for my next travel.

My flight was extremely cold. I had a jacket and a cover was left in each seat. The cover was extremely thin and I have a disability, fibromyalgia and arthrithis and AC air is the worst. I closed my vent and my husbands vent and it still was frigid. I asked the attendant if I could get another cover and she quickly almost dismissively and totally unconcerned stating, (I quote) (one per chair) and walked off so quickly that I didn't get a chance to explain to her that I literally have adisability. I didnt want to make a seen so I set on that flight for over 5 hours in pain, joints locking up and extremely uncomfortable. When my fibromyalgia flares up my joints not only ache but they will lock up also and it takes me days to get back to my regular self even though I take medication for it. I felt like it would not have hurt anyone at all for her to just give me an extra cover because I'm sure they have all types of medical issues in people that fly every day.

I wish I knew in advance that the connecting flight was by indigo air

I appreciated the vailability of wheelchair services for persons with mobility issues all the way up to the aircraft. What could be better would be the food choices.

Excellent service. The personal adaptation of menus and the individual timing of service of them is fantastic.

no qatar did noting wrong Kayak messed up my whole vacation . Went early to check in at The Cairo, Egypt airport to find our I had not tickets to board , Kayak and/or Affirm never sent the money for my flight that I paid for and booked. So I had no flight at 12am in a foreign country and I had to scramble and find anther very costly other option just so that could fly home. Fucken horrible experience.

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Awesome hospitality, awesome staff, awesome food & awesome travel time. Thanks

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

The flight was delayed and one member of the crew was a bit rude. But apart from that all good.

My baggage is lost. Flight cancelled, Rebooked ticket through long routes. Mental stress, emotional hurt

It never happened. Me flight from Doha to São Paulo was lated and the time of waiting for the luggage arrives when we arrived in São Paulo was about 1 hour and half. So it took a lot of time just waiting the luggage of flight that was already late, consequently we lost the flight to Recife with Latam Airlines and had to go to the Qatar office to arrange another flight to us to Recife, that one with Azul Airlines. It was more 4 hours waiting to this other flight to knows that this other flight was delayed too, total of 5 hours more at the airport to waiting to go home :/

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

Quick and seamless boarding. No entertainment but fast Starlink wifi for this short trip and the staff was really friendly.

I dread trans-Pacific flights. They are very long. This was my first time on Universal, and it was my best crossing ever. The staff were professional, the hospitality was great, and the food was delicious. The entertainment system filled the long flight hours. I will seek out Universal flights from now onwards. 🙂

The food quality sucks. One must starve if they do not eat flesh Or wheat based products Some variety would be expected. The trivial amount of snacks and or food is inhumane

We Left Calgary 1/2 hour late and that made for a tight connection in Denver. After arriving everything was done to help us make our connection. That was a great effort. Thank You United

Efficient all round, very good crew. Short flight so the food, of course, was just snacks

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

The experience was great, the crew was very polite and hospitable. I will definitely make if my go to airlines.

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth

This flight with a lot empty place , and I have more room, feeling comfortable.

Flight was good, breakfast could be much better. We had come from a domestic flight on the same aircraft and the domestic flight was much better regarding service compared to this international flight.

I accidentally touched a cabin steward as she passed by and she reacted harshly yelling in a loud voice “don’t touch me”. It was embarrassing and uncalled for. I would characterize a few of the cabin crew as pretentious and aloof. Not at all what is expected. That was the first leg of our trip from Montreal to Munich. The second leg from Munich to Nice was more in keeping with the service I expected.

The staff could not have been any friendlier. Lots of usb ports on our aircraft.

It was crazy, boarded over a hour late from scheduled departure. Then when arrived in BNA issued with getting off the plane…over 1/2 hour. Not looking forward to flying Air Canada, ever again.

Great flight. Only complaint is it took over an hour for my luggage to get to the carousel on the return to LAX That was irritating

The service to/from the airport/plane (wheelchair assistance for my mother in law) was exceptional. The staff was super friendly and courteous. The staff on the plane was also very nice. The food quality could have been better (mashed chicken sandwich).

The flight was great. I like it when airline capitalism give you information. For someone with flight jitters it really helps. And this captain was very cheery and reassuring. I had trouble understanding the head flight attendant because she spoke very fast. But overall staff were very helpful and kind.

1 hour late No hot drinks No restroom in the back of the plane

I did the posting for 45 years. I just retired. I’m the only seat in the plane but didn’t have any phone. It has to be mine so imagine seeing 13 hours on the flat seat with a belt that didn’t close all the rest was OK.
