Unfortunately, there has been a boarding and departure delay. However, as usual, the flight arrived earlier than the scheduled. There has been a turbulence in-between, it’s unavoidable. I couldn’t complain them.

Unfortunately, there has been a boarding and departure delay. However, as usual, the flight arrived earlier than the scheduled. There has been a turbulence in-between, it’s unavoidable. I couldn’t complain them.

Korean Air is unlike any other major airline I have flown with. The grace and respect that the staff has from check in to de-boarding is unmatched. The flight attendants this time were especially wonderful to my five little children. They helped us rearrange to more suitable seating, brought our children’s meals, and patiently waited for them in the aisles when they had to use the bathroom. We felt so welcome and comfortable. I really appreciate the meal voucher when our flight was delayed. I am grateful to have had such an stress-free experience.

It's good overall. Flight was packed. Inflight entertainment choices were lacking.

They were very accommodating of a dietary issue. Nice movie & tv selections. Non-stop helped get through a very long (15 hr) flight

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

The flight was on time and very quick, as expected, but the leg room isn't great in coach seats.

The boarding process for Korean airlines is very straightforward and easy. You've never met such helpful and friendly people. The food was great and the entertainment options were excellent too. My teenage boys found programs they wanted to watch while I had fun watching a full season of the Last Man - the Blind Investigator (Japanese), which my wife enjoyed too. My only complaint was that it takes a very long time to taxi at ICN (20 minutes) and the pilot had to hold at the gate for 10 minutes after our scheduled departure time, which meant we got to Seattle 27 minutes late. Luckily I had a long enough connection to make my next flight, but just barely.

Just a typical domestic poor flight nothing more. There is no food choices in such a flight. Crew doesn't really care if you are on-board or not

My second flight wasn't better than the first one. And this is 14 hours trip, crew came out only to offer food and the choices was poor. This food choices are good for Asian people but not for westerners. The breakfast kind thing was a corn sausage really disgusting. The air-conditioned blower really blow high and cold, turn out on my arrival to feel seek, that makes the trip uncomfortable. The crew didn't not really come out during the trip to offer drinks or snacks. No fruits available. Very poor service

Our seat row plus one ahead and behind we're completely overlooked during beverage service...

I like for how they process during check in. It was very smoothly.

The flight was scheduled for 2:30 PM. Early in the morning we got a text message saying the flight was delayed and rescheduled for 3:00 PM. We got to the airport with that in mind. Then we got a message during check-in at the flight was rescheduled again for 2:30 PM. We almost missed our flight. In fact, our bags Were told that they would not make it. At the end, everything worked out. But it is very stressful.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Excellent check-in. Crew was good. Excellent communication from flight deck.

Great overall. There was a bit of turbulence so they could only serve water because too much turbulence for the carts. Was glad they prioritized safety though

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗

5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

It was not a good experience. When I went to check-in one of Alaska's employees told me I had to check-in with Hawaiian Airlines, which was on the opposite side of the airport. I made my way over and when I got to Hawaiian Airlines they told me I was in the wrong place. The employee saw the look of defeat in my face and was able to get someone to check me in and text me my boarding pass. I had to make my way all the way back to the other side of the airport and barely made my flight. I think it would be very helpful for employees to be more informed with these Hawaiian flights that are operated by Alaska so they are not rerouting people to the wrong terminals. Also, clear signage in the check-in area.

Same as ive said before. All airlines and TSA need a massive revamp.

Alaska airline sis usually great. However flying nowadays is so stressful and feels more like an interrogation rather than a fun part of the vacation experience. From the TSA to the cramped seating it feels like i am entering a concentration camp having my picture taken via TSA and being forced to have my body scanned. Then we are forced to sit in beyond cramped conditions where our knees are crushed into the back of the seat in front of us with almost no movement possible constantly being reminded to put our seats forward when we want to alleviate the horrendous pain of our knees being shoved into hard plastic. My knees looked like i had kneeled on gravel for 2 days straight after flying for a total of 14 hours for my roundtrip. I keep hearing from our elders about the jopys of flying in the 70s and 80s but now it feels like the joy has been removed as a means of acquiring more financial gain by the airlines. Not to mention that my flight via hawaiin airlines was delayed so long that i had to miss my connecting flight which then forced me to miss another day of work and the only recourse i had was a wonderful conversation with a lady via Alaskan Airlines when she got me a new flight the next day due to the delay. She was very pleasant and helpful. She got me onto a nother flight the following day but when i have to travel 2 hours from springfield Illinois to st louis it was a huge hassle having the delay in the first place. Not even the tiniest bit of compensation was offered either. Not a voucher, not a free meal, not a slightly better seat, just a reschedule when in no way was the delay or the missing of the connecting flight my fault. I want to reiterate that Alaska Airlines is really one of the best airlines overall. I fully understand they dont control the TSA, but it does effect the overall experience when TSA is making it feel like we are going through a re-education camp with rather strange videos playing on the walls the entire way through Security. With that said, Alaska should take cosnideration from years of past and make the flying experience fun again. I understand profit is important, but if just ONE airline made flying like it used to be 40 years ago and stopped making it such a money-driven experience, then i, along with many others would choose to fly more often. We see the smaller soda cans and we laugh, we see the tiny snacks and scoff, we see the ridiculous wifi costs and choose to not pay for it because we download our own prior to flying. Why not get everyone to use the wifi by making it like 2 bucks rather than 8 bucks? Make a much larger first class area with slightly lower costs so it doesn't feel like we are mere peons boarding a cattle car? Create some more leg room and watch how fast people are clamoring for your airline over others. Not one airline is actually catering to the general public, if they did, they would see so many people seeking out their airlines above all others and it is just that simple.

Both flights were late 2+ hours with ZERO communication from the airlines or their staff. No offers for compensation. WiFi didn’t work for streaming and they said to only use browsing but that didn’t work either. Waste of $$. No drinks only boxed water or apple juice. No snack. One of the worst flight experiences I’ve ever had.

The ticket and bag check in was chaotic at SEATAC. No clear communication or signage for bag drop off.

This was actually an Alaska flight. I was not able to check in online using the Kayak app or the web for Hawaiian or Alaska airlines. So I contacted Hawaiian and they advised that I had to go to the counter when I arrive at the airport. So I waited in line at the Hawaiian counter for 45 minutes. When I got to the ticket agent she advised that I needed to go to the Alaskan Airlines ticket counter. So I went to that counter which thankfully was not busy. I received my boarding pass and then went to security. I arrived at the gate as boarding was beginning. The frustration is that Hawaiian or Kayak should have directed me to the correct ticket counter. When it is “operated by” a average person doesn't know what that means. Kayak app was silent on what action to take when I was unable to check in online and Hawaiian just stated my ticket number and confirmation numbers were invalid. Communication is key and this process could be cleaned up. Thank goodness I am savvy and speak English, I can’t imagine this process for someone who may not be.

If I knew I would be on Alaska Airlines flying back, I never would have bought the ticket. My flight kept getting delayed and Alaska always seems to be late which is why I don’t fly on them.

Good. They changed our gate very late and then when we landed, we had to wait 20 minutes to get off the airplane because another plane was in a slot.

Very nice experience. The boarding however seemed somewhat mixed up, and we were delayed taking off.

Flight was canceled with no voucher of any kind and next available flight was two days later.

Flight was on time. Boarding was smooth. Flight attendants were friendly and efficient. Entertainment system was broken for all passengers on the left side of the aisle. I would prefer if meals were not served on red eye flights. No one should need to dine at that time and it is disturbing for those passengers trying to sleep.

Gate agent did not hold flight for connection, provided no assistance to get new flight

Evidently, my seat had the only broken TV. I couldn’t plug it in, get it to come on, or watch anything, and of course, no one could fix it while we were on the plane. The service was good and the boarding was quick

United airlines, mediocre at best. No issues , nothing great . Worked for me

Efficient, calm when things were delayed and kept us regularly informed of what was happening.

it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

Boarding was mayhem. Late boarding by 15 minutes because of lack of staff (missing 1 flight attendant. We had to wait for an arrival of another plane before we could board). Flight was a little rough, but cannot blame on airlines.

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.

Air Canada never runs on time. You’re lucky if your flight is not cancelled or diverted. Worst airline in the world for gas lighting its customers.

No space in overhead bin, one cookie, 2 oz of juice - is not customer service.

Good flight, friendly crew and overall - good service on United Airlines.

Received email saying that there won’t be a seat back entertainment screen and inflight WiFi would be available. But no WiFi both ways. Say it in the email.

Somebody either kayak or Air Canada booked my flight under my preferred name Betty instead of my legal name and I almost was denied boarding my flight

flight landed late almost 1.00hr and we 4 passengers missed our connected flight to indianapolis, we need to get the hotel and taxi for the next day flight to home in indianapolis, cost us $ 300 more

Or the greatest and it ended up picking us up from Chicago to Toronto not sure who was tesponsible for the 4 hr delay. United should have been properly prepared for a scheduled flight from Austin to Chicago and they were not.

Good, only discomfort was consistent turbulence through the 3 hour flight. Not sure if in companies control though.

From the kind young lady (w/Vancouver air security) who expedited our check-in to U.S. Customs to the Air Canada gate crew who gave us pre-boarding, the flight attendants who actually offered a strong hand to help me board once I had surrendered my rolling walker at the door, they are all reflections of the thoughtful, genuinely helpful Canadians we have grown to appreciate. Water and other beverages were offered throughout the flight to make sure we weren't dehydrated and the cookie was great. (Husband bought the fruit & crackers snack,) I was delighted to see three movies that I would not have otherwise seen and appreciate that AC left the last film viewable until its conclusion although the flight had actually landed. Last, mahalo to the kind strong gentleman who not offered his hand to help me debark the plane, but gave me an AC pin that I'll truly treasure.

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.
