Airline reviews

Website could be better with faster access to specific flight information and boarding pass once reservation is made. Not a fan of no seat selection on line. I had to consult gate agent each time to change seats on flights with lots of open seats. This cannot possibly be cost effective for airline. On plus side, Alaska seat legroom seemed larger than American. ns

Staff inside Portland terminal were rude, made us fell rushed and not at all accommodating to seniors. For this alone I will probably never booked from them again.

It was fine—the seats are not very comfortable and the aisles are very narrow. Nothing different from other airlines

I booked a round trip. I ordered a lunch going and a lunch for the return but got both lunches going. Could have been my error. Both lunches were good.

Well the flight being delayed multiple time really was frustrating. But the crew and flight was good.

generally good. No snacks or drinks on the flight 3379 from Portland to San Jose, CA. Sad.

Everything except for the lack of a choice of the snack provided was great.

I like the friendliness of the staff. The food choices were OK. I wish there was more options. The entertainment through the movie portal was alright.

First time flying with Alaska, and it went great. Thank you for a great experience flying to PDX.

There was a very drunk man behind me who kept talking loudly to no one in particular. He was slurring his words and at times he didn’t know where we were going or whether or not we landed. He was also loudly using a lot of profanity. The attendants didn’t seem to notice or care and in fact continued to serve him alcohol. He was allowed to purchase 4 little bottles.

Not a comfortable trip, the seats are not good, and they look old.

Not entirely positive. It’s frustrating that everything is done through the united app. One of our flight attendants on our trip from San Francisco to MSP continually had trouble hearing people so she flipped her hair into people’s faces

I flew United from San Francisco to Auckland. My connecting flight from Auckland to Christchurch was canceled with no explanation. I was finally told the cancellation was due to fog. Even though it was clear when we landed. I am from San Francisco, I know what fog is! And I didn't see any fog. I was told the next available flight was 7 hours later. Unacceptable, they should have had a flight ready to go as soon as it was deemed safe to take off.

Our original flight was cancelled from SFO to AKL on 6/16/25. So we had to stay overnight at a hotel after a 12-hour layover plus 3-hour delay before the cancellation. Then had to fly to LA and then to AKL the following day losing an entire day of our vacation in NZ, that we can never get back.

Full flight. Flight attendants were harried. Otherwise, fine for the typical cramped seating conditions in coach.

Great! Flight was delayed by 30 mins but all was great. Thanks.

The 10hr flight was a comfortable as it could be in row 57. The food was just very bad….bland and soggy!

The business class upgrade meant a good sleep on the way home after a long week away. Excellent service, great food, and comfortable seat/bed for the journey.

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

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

The food was terrible especially for a 15 hour international flight. The crew was unpleasant as well.

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.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Quick check in. Everything went smooth. I don't know what can be done about airline food.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

Delta made it easy, comfortable and timely. The crew was fantastic.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

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

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

We had to deboard 2 times due to maintenance issues. They changed the plane, and then we got deviated to LAX due to maibtenance issues on the other plane, had to sleep at LAX and los a full day.

Everything was good, except the seats in economy were so close together, you could barely get out when the seat in front of your was reclined. If the airlines keep jamming in more and more seats, it will become intolerable. I will look for another airline that considers customer comfort and does not keep adding more rows of seats for more profit.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

IAD with the archaic people movers is just a place to be avoided.

Great service on board. Boarding a bit slow due to process. Food was pretty average.

Tastless food and too obvious lack of enthusiasm for service in the economy vesus business class

All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

I had no checked baggage but was required to hand over carry on baggage at the door of the plane. There was a lot of overboard space in the plane and I was one of the last ones. I ran to get my carry on but it was gone. I was given back at the plane door in Toronto, so the wait was not as long as it would have been at the carousel.

Armrest controller on my seat 35D and nextbooennseat 35E did not work right. Hard to press buttons to recognize and 35D had constantnpressure either upmost down somit was nearly impossible to make selections. .

For the price, it was a really good experience. There was no entertainment on board, so I couldn't really rate this, and I didn't order a meal. I appreciated that there was a free glass of wine.

Short flight. Everything was fine except the flight was delayed twice for a total of an hour.

My flight from New York to Canada and Canada to Brisbane was canceled, so I had to take united airlines instead flight from New York to Dubai then layover in Dubai 8 hours then from Dubai to Brisbane it was extremely difficult for me , it was a nightmare flying with Canadian airlines unfortunately.

I found the boarding easy and my seat was very comfortable as I had a lot of leg room. I am not too happy that I no longer have lounge access even though I used to get it with my TD credit card.

Flight cancelled. Major disruption to our travel. Do not use Air Canada from KC. To few flights.

Real smooth and easy, Real good leg room in coach!

There labor disputes cancelled my flight less than 24 hours before my boarding time but there customer service/website was easy enough to navigate and they rebooked me for no upcharge.

Re luggage I carried a backpack only. I did not check any bags in. However there were other passengers with carry on luggage going in the plane. My question is why are others allowed to have a carry on luggage inside the plane? Shouldn’t they have dropped it off at the gate? I’m asking because I could have brought the same thing instead of a backpack only. Please clarify for future reference. Thank you.

Like the service. Very hard to communicate or contact when have problems

Very bad, flight was cancelled due to strike and staff was unable to rebook us
