I am truely disappointed in the delays. I have been flying Alaska Airlines for years and years and have always had the most amazing experiences. Not what has happened with being on time. Flying from SAN to PDX delayed. Then .PRX to SAN delayed,

Was very easy to board but when you get to the confirmation board it was too high for me to see even with my glasses so I just hoped that I was lead to the right gate and waited for boarding.

The crew at the airport and in flight were excellent, the seats were a bit cramped but I am tall so maybe someone shorter wouldn’t care. Not many food options unless you know to pre-order. I would definitely fly them again but would pay for emergency row and bring food. Flight was perfect, arrived a little early.

A refund because I never got on any you guys never canceled it in the first place

They removed the cover off my checked bag and threw it away.

Your seats do not recline more than 2”. That’s a shame on a 5+ hours flight especially overnight flight. Garbage airline

It was delayed seven hours and we did not take it

It was a terrible flight! We were delayed 2 hours just sitting on the plane on the way from San Diego to Raleigh. Coming back, we were delayed again in Raleigh for about 40 minutes, when we got to San Francisco, we got delayed again due to no gate available. We missed our flight to Fresno due to all the delays!!! We had to wait in a long line to get compensated to stay in a hotel and this was about mid-night! The staff that talked to us did not even apologize for the inconvenience that happened! We were already tired from traveling and we had to deal with all the delays! The company has no consideration of their customer's time. We completely wasted one whole day just dealing with this delay and had to get another sitter for our dog because we couldn't get home that night. This experience was very bad and I would not want to fly Alaska airlines again and would not recommend it to anybody!

The problem was going through San Diego, a trip that's become a new development.

Flight was canceled in good weather due to mechanical issue. Rebooked to flight to different airport in area that landed 7 hours after initially planned arrival. We had to jump through hoops to get taxi reimbursement given flight landed in different airport at 12:45 am.

New aircraft and flight was running on time, but adverse weather conditions meant we were unable to land on the first two approaches. Third attempt resulted in a very smooth and safe landing.

Very good it will be my choice of airline while in Australia.

Flight cancelled due to broken seat. $8 refreshment voucher barely bought a coffee. 3 hours to next flight. Also then delayed.

There were no food or entertainment on this short flight. Friendly staff even before getting on the flight. The seats were snug but it was quick flight

Good flight. On time. No problems. Plane was clean. Service was as you would expect. However nothing special, just a good flight.

Very friendly staff. No food service and no entertainment. Only 1hr 20min flight

High fees for excess checked baggage and somehow ridiculous rules for carry on bags.

Flight was late, food and drink an extra charge, my carry on is five rows behind me, and the seats are too narrow. Don’t ask me to be happy about it

I bought flights in August and there wasn’t a flight in the system

Our 6.30am flight was boarded then cancelled to fly at 10.55am . We were flying to Brisbane to attend a funeral at 12 noon an hour away . This means missing the funeral due to unreliability of Virgin . Unimpressed !!

Overall, it was a very good experience. I would have given it a 10/10, especially based on our flight from SFO to Melbourne. The cabin crew on that flight were wonderful and incredibly attentive. They took extra care when setting up our beds so we could sleep comfortably without being disturbed. Dinner was served promptly and smoothly. I woke up quite late, when the flight was already preparing for landing, and the crew still made sure I was taken care of. They brought me English tea in a proper cup, and when it was time to prepare the cabin for landing, they thoughtfully transferred it into a takeaway cup so I could continue enjoying it along with some breakfast. Those small, thoughtful gestures made the long flight feel much more comfortable and special. The service from the SFO to Melbourne crew was truly excellent.

Loved the food and beverages available, spacious economy class, excellent entertainment

Very good overall. Highly recommend for all flying to Australia

We had bulkhead seats in a A380 in the upper deck in seats 31 D and E. Storage was very limited other than in overhead bin - which is not within reach when in seat. Yet paying same price as others in premium economy who have a lot more storage within arm’s reach. Seems very unfair.

When I originally booked this flight, I was expecting to travel on Qantas. When the itinerary changed and the long-haul segment was operated by American Airlines, we were disappointed but remained open-minded. Unfortunately, the overall service experience fell far short of expectations. This was a long-haul international flight. Getting up periodically to use the restroom or stretch is inevitable, especially on flights of this duration. However, each time we stood up, we felt as though we were inconveniencing the crew. The tone and body language often suggested that we were in the way or disrupting something simply by moving about the cabin. As a result, I avoided getting up as often as I needed to and was physically very sore upon arrival. Meal service was similarly impersonal. The options were presented in single words “beef or veggie,” “pasta or beef” without any description of what was actually being served. There was little engagement or courtesy beyond that. Even simple expressions of gratitude were often not acknowledged. I am accustomed to no-frills travel and do not expect luxury. What was disappointing was not the absence of extras, but the absence of basic warmth and professionalism. On a long-haul international flight, small moments of courtesy and humanity make a significant difference. In this case, the experience felt transactional and dismissive rather than welcoming. I hope this feedback is taken constructively, as there is a meaningful difference between efficient service and indifferent service.

Business seats not as comfortable or private as most competitors (e.g. Qantas was outstanding), and movie selection was much more limited than Qantas or United has been recently

Hard to move and get out of my seat when the passenger in front is in recline position.

I tried to check in online but was unable to do so. I stood in line for nearly two hours to check in. American Airlines was understaffed. When I finally got to the kiosk to check in, I was still unable to check in. No AA staff was available to help. Finally one of the airport security agents who was helping passengers became of lack of AA Staff told me: “I think the reason you can’t check in is that you are starting your name with an upper case letter when you write it. Just write it with all lower case letters.” That did allow me to check in. HOW COULD ANYONE POSSIBLY KNOW THAT IF THEY USE AN INITIAL UPPER CASE LETTER TO SPELL THEIR OWN NAME, AA WOULD NOT ALLOW THEM TO CHECK IN?????? Then I had to wait in line over half an hour again to drop off my baggage. Although I arrived at the airport 3 hours early, by the time I got to the gate, they had already started boarding.

Their aircraft are old and amenities lack way behind other international carriers leaving from BNE. Even in economy

Friendly staff, surprisingly good premium economy seats allowing good sleep/ snooze opportunity and very good menu.

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

UA594 was delayed multiple times. I ended up getting picked up so I can make it in time for work 6AM on Monday, 7/6/2026

Uncomfortable plastic seats even in premium economy. No free wifi. Even paid wifi was spotty to nonexistent. Bad food. Much worse than economy on foreign carriers like Qantas.

Good flight. However, when booked flight with United, assumed the layover included by United in San Francisco of 1 hr and 40 minutes was sufficient . Not so and would recommend at least 2 hours or more. Needed to go through US immigration (very long lineups), then pick up bags, take all the way to another terminal, running because we did not have sufficient time. We made the flight because they held the door for us but luggage didn’t follow.

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

Was a pain having to leave the plane and reboard but glad the plane was fixed

Connecting flights were poor,especially in Naples.our Lufthansa air bus was a joke.way too small for that long of a flight.no room at all.couldn’t even get out of the seats to move around or go to the bathrooms.we thought we were getting an actual air bus,double decker.i will never fly that long in a plane like that again.kind of misleading to call it an air bus.we actually had more room on our buses that we used.

For a 22 minute flight all you expect is for it to be safe and comfortable

Lost connnection had to stayON in Chicago Was a mess

Booked economy through United - air canada treated it as standby and was almost refused boarding.

The help at check-in area was excellent! The crew on board was great and the legroom and entertainment is excellent!

Nice crew - very small plane and uncomfortable, with no entertainment options…

We were given an upgrade which provided more seat room and a meal. However seat designated overhead locker space was used by others.Boarding was delayed with part or the delay due to staff assisting diaablef individuals aboard. Personal observation would suggest that 3 individuals rorted the system. They used wheel chair access to the plane, boarding with family ahead of al other passengers, but required no assistance until boarding occurred. On departure 3 “disabled” individuals were seen walking freely near the baggage carousel. One person even assisted with a luggage trolley! The rorting is most likely widespread and not airline specific

Not good with Kayak … There is no customer service number to call ?? We have stuck at Toronto airport but air Canada don’t help because we bought tickets thru Kayak .. Kayak should have customer service number listed for help .. Very bad .. we will think twice to buy the tickets thru Kayak next time.. Ahluwalia

We paid $110 for more leg room. My traveling companion’s knees were right up against the seat in front. Where was more leg room. We feel ripped off. Food,,,there wasn’t any not even a bag of pretzels. As a result, there was very little service.

A 6 hour flt and only offered water twice the entire flight. A small bag of flavored pretzels was offered as well w/ the first round of beverages. The landing was ‘hot’ but I arrived safely. The plane was nice and new and the seats were roomie. I’m use to warmer more generous hospitality but all and all I’d fly with them again but I’d bring more water and snacks.

Headphones for the movies have too much bass and can't be adjusted. Almost impossible to hear. Great movie selections but can't really watch them because you can't hear them. Also the system is very slow.

No food for a 6 hours flight! Plus very expensive to buy ! Sit uncomfortable! Awful!!!

Air Canada didn't properly check the maintenance status of the plane prior to boarding it's passengers on to the plane. A final check before liftoff and we had to switch planes because of mechanical flaps issue.

The entertainment system is very slow. Scrolling through selections is slow.
