Matsuyama to Tokyo is basically a puddle jumper flight, so it was as good as one should expect. No meal, no entertainment, and none expected.

Matsuyama to Tokyo is basically a puddle jumper flight, so it was as good as one should expect. No meal, no entertainment, and none expected.

The staff is amazing, I cannot stress that enough! The food is really good and snacks at stations to take for yourselves. Economy seating is fine, not the most comfortable, but our friends in Premium Economy said they were very comfortable! Decent entertainment options, but being built in, you have to use their cheap headsets unless you have your own plug in ones. I only have Bluetooth earbuds.

Seats were extremely cramped even for economy. Food was atrocious. Crew was fine but no follow up, additional drinks offered etc. For a 14 hour flight I expected more.

Boarding was good. Inflight service was good. Alcoholic drinks could have been served free.

Suite lounge in Honolulu is the best lounge in Honolulu. I love the huge bathrooms in ANA first Class on the A380 Honu plane. Japanese meal was outstanding and service was amazing. Everything was just excellent. Can’t wait to fly again

The bed / seat was very hard , not at all comfortable for an 11 hr flight .. food was strange , never have I eaten roast chicken and mash potatoes for breakfast!! Very odd

Their was $200 charge for 2nd luggage, airplane very new and flight smooth. Flight time seem faster then Asian stoping Korea then china.

Delays, plane transfer due to malfunction, no entertainment, limited beverage service.

Seat was broken. Check in was not possible until we reached the gate, by then we were separated.

The food was not great; but I don’t expect much from airline food. However, the staff was incredible! I had gotten to the gate when I realized I had left my computer at the security checkpoint! I told a staff member and she said, “well, you will miss this flight if you go back to get it” It was a long way from the gate. I asked if I might get on the next flight. She sent for another staff member, and he took me to the gate desk. He found an open seat, and said,”okay, go run to get your computer, I will get you a new boarding pass.” I rran back, retrieved my computer, and returned to the gate. It was closed, but I found the gate nearby where the next ANA flight was leaving. Another staff member was ready for me, and printed me a new pass, and even made sure I still had an aisle seat that I requested! I got in line and continued my trip. These people are amazing, helpful, and friendly. My trip could have been ruined, or postponed at a great expense, but they saved the day! 5 stars!!!!

Pretty smooth ride!… a little tight in the back and would’ve loved to had a movie screen… couldn’t beat the price to the West Coast!

I like not much people. Could tell the kids to be quiet.

I liked everything except, I left a brand new Switch 2 on the plane and talking to anybody about it is nearly impossible. I had to fill out a form and hope they get back to me in the next 2 weeks. I really hope they contact me. I saved for that thing for over a year and my son is heart broken.

Fight attendant excellent Food very good, not great Seats were stiff and uncomfortable Flight was overall very nice. Last three flights were burdened with miserably uncomfortable seats. Hard stiff no padding.

The ground crew was very good. They communicated clearly and continued updating. The flight crew was fine. The flight crew on the March 20th flight from MCI to Portland was excellent.

Flight on time. Easy boarding. Changing my seat was very easy.

Fine for a short flight. All went well. Snacks are lacking and I couldn’t hook up to wifi through the app, but it was fine.

Aircraft was freezing, cold air blowing on me the entire time and the individual fans were turned off.

The flight 2161 was cancelled after repeated delays; for some reason the crew and not the tower located in Billings, Montana made the call. A cancelled flight is not a big deal, it happens. It was very disappointing that upon cancelling the flight it was a free for all to get to the counter for rebooking. Priority seating and first class ticket holders should have been giving priority to get on the next available flight. Most would agree that the process of moving states away, w/a cat, is stressful. A cancelled flight, 90 minutes to rebook, no place to stay, medication that was to be refrigerated and trying to find a local pet friendly hotel significantly added to the stress. Had I been able to rebook (per priority boarding SOP) I could have called the place I had just checked out of as my room most likely was just as I'd left it, including with pet supplies (which also had to be repurchased). While waiting to rebook, many of us called Alaska Airlines 800 number hoping to get a new flight; the waiting time -- this is not a joke -- was eight (8) hours, which dropped to "just" two (2) hours about 45-minutes later. Due to the cancellation I had to spend $268.75 and I still have not been refunded for the change in ticket (first class to regular). Each time I've call, five times now, the wait time was absurd, or a message of call back is given. Hopefully visiting the airport and talking with an agent face to face will be the final chapter to this experience. Alaska has been my go to air travel for years, hopefully this trip was just a hiccup. A system that forces customer's to spend hours of their time (money) to get a just due refund is not a working system. I suggest Alaska Airlines hire more representatives to handle calls; time is more valuable than money, spending 90 minutes to rebook a flight, without the difference being automatic is absurd. There are things called computers, they do amazing things. Once the flight was cancelled, only three agents were working to rebook the PAX, This too was unacceptable. First class ticket holders pay for first-class service, this should include rebooking on flights that are cancelled. I recall a time when flights were cancelled the airline would offer a hotel should the next flight not be until the following day? I had no idea that was no longer SOP; many could return home, several of us could not. The agents were pleasant once the PAX had their turn to rebook, this was true down in baggage area as well. The flight out the next day was also what I'd come to find of Alaska Airlines.

Never got on because first part of trip was cancelled and we have no idea when we will get rebooked…

The flight was smooth, the crew was great but the plane was quite old

Everything was great until I lost my water bottle and they can’t seem to locate it. I know I left it on the plane though.

WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.

The crew bent over backwards to thank us for flying and make us comfortable. The food service was quick and efficient. The Captain communicated and said goodbye and thank you as we departed. They really stood out!

Okay considering we had weather delays which the Pilot notified us of immediately!

Generally on time departures and arrivals, clean planes, sky miles membership provides great benefits (complimentary upgrades, etc).

Flight from Fort Wayne to Atlanta was the smallest in terms of cabin space that I've ever seen. A carry on I've used for 20 years BARELY fit in overhead compartment. I'm 5'10" and felt very cramped. Not the best experience.

I am writing to express my dissatisfaction with the poor service and unprofessional staff we encountered when traveling with an infant. Our flight was delayed, and the gate staff failed to manage the boarding process appropriately. Due to incorrect, unavailable, or missing 'pink tag' stroller and car seat check-in procedures at the gate, we were forced to board last. Furthermore, the gate staff was rude and dismissive, causing significant distress to our infant. To make matters worse, one of our checked items—an infant sleeper/lounger—was returned to us broken. Given the unsafe handling of essential equipment and unprofessional treatment, I expect a prompt resolution regarding compensation for the damaged items.

We departed and landed early which was a nice surprise. The boarding process was slow.

N Everything was perfect from boarding to assistance to baggage in Tampa

It's a long flight and I would have liked better snacks between lunch and the arrival meal. It's fine to have fruit and nuts but I really don't like ramen because it's salty junk soup. I'd suggest sandwiches. They're not expensive nor are they hard to store for a long flight. The FA's had a couple of big services and they were super busy preparing, executing and then cleaning up. Then they disappeared.

Great flight. Got to watch a movie. Smooth flight and early arrival at ORD.

This was the first flight in the morning. We boarded fine. The cabin door was closed and we were ready to go. We were notified by the Captain that ATC issued and ground stop for 40 minutes. So, without even pushing back from the gate, we were already 40 minutes late. We actually were released to push-back and taxi at 30 minutes. But, some passengers had tight connections and were not going to make their connections. Some passengers asked about the delay and the effect on the connections and were told by the cabin attendant that all flights will be delayed and so they should be OK. However, that was not true. My connecting flight was on time and I arrived at IAH with 21 minutes to make my connection. I did and I'm happy about that, but the flight crew should not have given assurances to the passengers who might have missed their connections.

Poor communication, flight was delayed for preventable reasons. I missed my connection.

It was better than excellent. The staff in Mason City were great. The young woman that pushed my wheelchair did more than could be expected of her. She came from India 17 years ago. I don't remember her name.

After arriving in Chicago, we were taxiing for 1.5 hours with infrequent and untruthful updates about the amount of time it would take to arrive at the gate. Minimally, the team could have provided timing expectations that were more truthful, especially one their original expectations were not met.

All good flight was 35 minutes early when arriving in Edinburgh

Flights were on time actually early service was good and crew cheerful

Every staff member was professional, friendly and courteous. The pizza twist was ok. It was warm but too much dough.

The boarding timing needs to be improved. The flight was delayed again because it took way too long to board. I was already exhausted from sleeping at the airport and spending all day there due to delay from my previous flight that connected in Chicago.

Flight home was delayed multiple times, did not get home until 2am

the check-in lady at ORD was extremely rude and unprofessional. very disappointed as it was supposed to be a celebration for my wife's birthday and it really put a damper on things. if i wanted to be treated like trash, i would have flown Economy! (as opposed to business class)

My original flight was cancelled and then rebooked four hours later on a recovery flight, but I was checked in as stanby and had no seats so as a family of four we were concerned about not being seated altogether. Our flight then got delayed by another 1.5 hours and when seats were assigned at the gate, three of the four of us were together and we could get my wife closer, they offered no assistance.

The plane was very cramped to point there was no way not to touch person beside you and a stewardess screamed at my son when I touched her arm to get her attention to let her know she forgot to give him his dinner when she passed him and gave a dinner to passenger behind him. Very inappropriate response and She never came back to apologize and other stewardess said she was sorry “if I felt” she was inappropriate. Horrible experience and she should be reprimanded for her behavior

I bought a ticket from Kayak. When I got to the airport, the was no ticket. I had to pay 5X to get to my destination. No response received from Kayak. I will NEVER use them again.

My wallet was stolen while I was sleeping on the plane.

Good boarding but extremely cold temperature in both flights (60 F!).

The whole plane smelled and felt old. The seats were very uncomfortable. Multiple delays. Extra fees.

Very rude gate attendants in San Francisco who didn’t let me bring my little carry on (smaller than usual size) and after boarding I realized that there still were a lot of overhead compartment space (like a full section available in some spots). That made me lose 30 minutes at my destination at 1am and it could have broken something fragile that I had in it

The most uncomfortable flight I’ve ever been on. I’m only 5,4” and barely had enough room to exist, couldn’t even fully relax my shoulders. Not sure why they bother with snacks. Half a coke and a single cookie?? Wow. Purchasable food looked gross too. Remember when airlines used to treat you like a human being?
