OUr pilot was very good and also a good landing in a very gusting Phoenix. Most important.

It was alright other than the changes in the Alaska Lounge. That and the migraine I had were disappointing. Other then that everything went well.

It was a short flight so no refreshments or entertainment which was fine.

Flying in both directions across country the gate designated on my boarding pass was wrong. From w to e across the country the passenger next to me coughed the entire way.

Although both planes (flights) had mechanical issue delaying both of my flights, the crew members handled everything with ease. Both flights had the smoothest take off and landing. I opted to upgrade my seat to first class and really lucked out getting the seat at the very front of the plane. Awesome treat to myself. I really enjoyed my flight.

The staff from check-in counter to the flight crew were great. Flight was right on schedule. 10/10

Changed flight from San Fran to Seattle Then with a Delayed takeoff barely made my connection Waited over an hour for luggage 😜

It was good. There was a mistake made in Seattle. Somehow we were bumped out of our seats as if we weren't on the flight anymore. The woman at the gate caught it and announced our name to come up and she fixed it.

I wouldn’t fly with Alaska again if you paid me.

I appreciated Alaska Airlines very much, they are expanding traveling locations globally as they partnered with another company and am excited and looking forward to our next traveling adventure with this great Airline. Thank you kindly

Flight was delayed due to weather. Crew did a nice job of making us comfortable. No complain complaints.

Our bag was lost so that made unnecessary chaos On our trip

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

Delta flight was on time, seats were comfortable, and crew was nice.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

It was an overnight flight and I desperately needed coffee before we landed, but Delta does only one beverage service, and that is shortly after takeoff, not before landing at 5 am.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

I love the “boarding from the back” idea - it’s so much better than the “Zones” idea that many others use. Also, the inflight wifi was a first for me! Very nice to have on a 13-hour flight!

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

Arriving at Coolangatta, rows 20 forward, took the airbridge across to the terminal. It was suggested to those from rows 21 back, that we take the rear stairs and to be careful crossing the tarmac. That was all well and good. However, when we got across to the terminal we then had to climb three large flights of stairs to meet up with those coming across the airbridge. No elevator! There were people carrying babies and elderly carrying hand luggage that needed assistance from others.. There was no option to turn back.

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

Economy was much nicer on the Air New Zealand planes.

At Coolangatta International it is difficult to hear voice boarding announcements when away from screen announcements.

Flew premium economy, well worth the extra. Much better seat size & space. Meals & snacks were lovely. Crew really pleasant. Internet is not great, not really useful for anything. Couldn't even send messages.

Everything was fine. Wish the wifi was free and included in the ticket price.

Nothing special short flight - all good - difference between 1 fudge and 2 fudge is obligation and thankfulness

The flight we had booked was cancelled due to bad weather conditions, but we were lucky to arrive at the airport quite early and got a seat on an earlier flight. The flight was mostly nice, but there were some hefty turbulences towards Queenstown. One of the passengers behaved hysterically. It would have been great if the crew had done something to calm her.

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

A bit rush for transit. Food and entertainment are not available

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

Multiple delays and not straight answer from the United team

For economy, it was very good. Staff was great, they even let some of us change seats for more leg room... Put an empty seat between us which was fantastic for a 12hr flight. Onboard entertainment was excellent, I think over 200 choices of movies/tv/etc The bad was the barely/nonfunctional wifi that cost either $16.99 or 1700 miles (full flight). It was atrocious... Definitely the worst of the last 3 long haul major airlines I was on the last few months.

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

Electric plugs didn't work. Entertainment system wasn't working

All was good except for the seats, not very comfy.

2.5 hour delay sitting in the plane on the tarmac, you tell me how the experience was

I hope these comments will find their way to AC customer experience team. Me and my spouse 50 years of aged coming back from 7 days perfect vacation... While boarding in FLL flight AC1621, one of the boarding agents (tall aged african american) man literelly yeld at my wife during the picture talking process. MAM ! STEP !! BACK !!! We are not illegal immegrants beying deported, nor are we in the millitary. We are customers returning home. This was unacceptable. While boarding in YYZ flight AC1154, one of the boarding agents (tall aged caucasian) man criticied with several complesant remarks my passport condition saying that I could not travel intl with it due to stain, decoloration, and BLOOD. My passport does not have blood on it! Yes it might be in less than perfect condition, but their are ways to talk to customer that does not imply not allow a boarding agent to be angry fathery like, or a custom agent looking at a suspicious individual. Both experience were less than acceptable for might I remind you a paying CUSTOMER returning home.

Short flight so no food or entertainment. Good landing at SFO and on time. We were told no carryon luggage yet lots of people were puting bags in overhead compartments. The rules need to be made more clear. I was on the first leg of an international flight and this is the first time I could not have carryon luggage.

This flight didn't happen for me because of overbooking.

My flight was overbooked and they would not let me board. I had to book another flight and pay the full amount of that flight. I did not get any help at all from Air Canada or United Airlines.

Comfortable seats and movies entertainment available. Better experience than the flight from Toronto to Denver.

Poor air traffic controller staffing led to a 50%reduction on flights so we got to wait 4 hrs for our flight! Very disorganized at the gate Poor communication with customers

It was delayed by almost 90 minutes and that messed up our plans but it was beyond UA’s control that is what we heard

Terrible experience, flight was delayed both ways. Limited compensation for the 5+ hour delay. Will not be flying Air Canada Rouge, and don’t recommend you do either.
