The cabin was immaculate, attendants were friendly and efficient. The food selection was appropriate for the flight length.

Starlux is good, however the late boarding from Sea to PHL was frustrates. But it's nice for Alaska to owner the agreement with Starlux.

Nice plans, good food, nothing to complain but the entertainment are out of date programs.

The flight staff was wonderful, especially Jessica, who was extremely friendly and attentive. The food on the plane was ample and delicious. The only negative experience I has was that I was pulled aside for an enhanced security screen at the gate, after my ticket was scanned and I lost my place in line for boarding and went from number 3 in line for zone 1 boarding to actually getting on the plane with the zone 2 and zone 3 travelers. I was almost dead last in getting into the business class section. That's a lot of money to pay for a business class ticket to get pulled aside for nothing.

Counter personnel were friendly and professional. Assured me my bag would reach Bangkok without having to get it and recheck it for my international flight from Seattle. Also printed out all of my boarding passes for my trip.

Was not able to buy wifi on the plane given, not available for economy tickets. Was not clear when buying the ticket that this was the case.

The food was amazing good especially for evonoply. The seats were comfy more then usually..crew was very nice and helpful.

The overall experience with STARLUX was phenomenal. One of the best highlights for me was the smooth landing in LA(smoothest landing I’ve experienced ever) and the attentiveness of all your staff from check-in to boarding. Also, flight left and landed between airports on time. I highly recommend Starlux to my family and friends and I’m excited to fly with you again.

We are scare because almost missing the fligh from Seattle to San Diego ! Starlux not have enough members for servicing with wheel chairs? We almost left behind , so we must walking !?

Crew is very attentive. Another new airbus 350-900 plane. Very modern.

The plane was half empty and I lucky to get three seats to myself allowing me to stretch my legs. Even without that the regular leg space in economy was quite comfortable compared to some other planes in recent memory. Food was fine I’m not vegetarian, but neither of the options offered was. So order vegetarian ahead when checkin in.

Picked our seats when we purchased this flight (2 seats alone on the right) but were assigned two middle seats in the middle row at the gate. Very disappointing for a 10 hour+ flight, and what is the point of picking and paying for seats ahead of time when they just reassign us?

First international flight where the meals were not to my taste.

Its fantastic!!I like the food the serve in EVA air😊

Awful had to ask for a supervisor to sit with my flight companion even t booked the tickets together weeks before

I have never heard of EVA air before but I am so happy my wife and I were able to flight on their planes twice. Everything on these flights just felt better than their competitors. As someone with longer legs any bit of extra leg spaces is appreciated. The different options for food and drinks were also a plus. They were extra careful to make sure my wife's eating restrictions were taken care for. They had a before take off and landing announcements on the built in tablets for each seat and it gave out information that was very helpful. Such as what and how to declare your items in the specific country you landed in, any odd items that may be illegal to bring it (and even the reasoning why) and any other information you might need to make your post flight experience better. Oh and the seats were more comfortable, had more ability to lean and the headrest was much better for flight sleeping. The only downside was there were "forced" ads on the tablet at take off for maybe 5-10 minutes but honestly, this flight was the cheapest option and had all the benefits listed above that is such an easy trade off. Im keeping an eye out for EVA air going forward.

Great but I am not sure why I was placed in zone 4 for boarding despite being an Infinity Member??? Can you explain online. Thanks

Plane is new and I was upgraded to first class so all was great.

I was expecting that movie selection and food would have been better. Everything else was great.

Eva is one of the top airlines in Asia... but often are over priced. Finally found a reasonable rate.

Refer to the Osaka-Tokyo one, it explained how I felt about both flights

I am a United 1K flyer but certainly I would fly ANA again. Great inflight service!

"The Room" is the only way to fly. The service was excellent and the stewardesses we all gorgeous and friendly. The boarding process was delayed and the attendants at the airport were not the best.

Great. Very helpful staff and accommodating. The flight was also smooth

My son flew and had a great experience.. thank you for taking care of my baby

I enjoyed the flight, but a little too much turbulence on the flight. Thank you for the meal and entertainment. This kept my kids entertain during the flight. I have to admit comparing the crew from ANA vs United, there was a sense of more accomodation, friendliness and service compared to United crew. I felt for the United crew, it was just a job and it can be seen in there demeanor and delivery.

Attendants were very kind and frequently offered water and snacks. Food was excellent. For some reason, my IFE system would not play dialogue for any media despite my efforts to change to different language voiceovers, restart the system, etc. so I could not watch any videos.

Choice of movies dated as with the screens. Major room for improvement on the software to sort and select choices.

Although the crew was eventually very good, they complained loudly about EVERYTHING before the takeoff. Did not set the stage for a good trip in business class. The western meal choices were pretty mediocre as were the wine choices. We took an ANA flight to Tokyo and they were outstanding!

They did not get my request for veg food that i made a month ago. Also did not have any backup veg food on board or fruit plate or simething. Very disappointing as i had hward about how grwat ANA was supossed to be. Alsio entertainment was lacking and screen and tech was subpar. Overall just mid to low tie. They are living off reputation and are being passed up by most other carriers.

The back of the plane use to board first after handicap with children and first class. Now the back boards last and there’s a long line waiting to go back while everyone is putting their luggage up and standing in aisle just talking. It’s hard on the elderly. I’m elderly.

Crew was fine.at check out I didn't get my debit card back.and didn't know until I was in Seattle. There was a 5.5hour delay. I didn't get to Washington til 530this morning. So now I have to get a new card and change alot of stuff.

For the third flight I’ve taken on Alaska this year there were delays. It’s become almost a gamble and hope for the best especially catching the late flight out of Kalispel to Seattle. Don’t even get me started on the flight out of Seattle to Sacramento. I will try another airline whenever possible moving forward.

Like to get onward pass from Alaska airlines and Cathay Pacific more seamless. As the online check-in procedure you sent didn't work and I have to get to the airport really early to check-in with counter.

I was a late add on to this flight because my previously booked flight was delayed, which would have made me late for my connecting flight. I was given the last seat on the plane which isn’t a huge deal but the seat had lots of dust and black mold looking growth along the air vents, making me uncomfortable with using it for the 6 hour flight. There was a gross fecal matter looking stain on the edge of the window in front of me. I paid for the WiFi, which did not work for the most of the flight.

The flight itself was good but I am not a fan of a lot of people and so much sensory I couldn't take that part. My brain went into rescue mode cause there was to much going on. I am to interverted to out here peopling. I like the emergency section but when I feel like I am trapped cause there are people next to me I almost wanted to jump out to be honest. I didn't obviously but I now know what all I can handle and what not. Thank you for hearing me out. If there are better times for people with sensory issues and having borderline personality and anxiety issues please let me know

This was the worst flight of my life. I was placed in 33D which should not even be considered a seat. If anything it should be a heavily discounted seat. Aside from the usual more tolerable issues (no leg room, delays, poor snacks, the air vent smelling moldy, etc), this location was plagued by being placed directly in front of the bathroom door with all of the fun smells and sounds. The worst part was that there was a dozen available seats on this flight and was unable to moved my seat to any of them. I find it unbelievable that this seat was first assigned over any of those. Very disappointing.

Alaska Airlines has great customer service. I would like the Alaska lounge to improve with food options.

No free internet, lazy flight attendants that did not like to serve drinks. Blamed it on turbulence but there was not any.

Gate agent was VERY efficient, even as his 2nd wasn't there. But... Great Landing! (I suspect he's done this before.)

Rude staff from baggage check to gate crew. Poor instructions. Inconsistent application of baggage rules.

more room in seats, larger snacks, more comms with delays

The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.

One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

They did everything right and everything happened right on time.

Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Much better than I expected. I had an economy ticket so I was really happy the flight was so comfy and the service so generous. Passengers were all polite too.

I notice that every time I fly delta or any American carrier, the staff seem tired, overworked, and not at the service level I’m accustomed to in Asia. They frequently crash into my arm when coming down the aisle. Food is shoved at my face with no greeting or verbal cue. The food portions seemed much smaller than usual and didn’t see much wine or beverage options. This is comfort plus? The plane was old and tired. The bathroom was dripping with mineral stains after a long lack of cleaning. The power socket did not work, although the USB output did. I really wonder why I’m flying Delta, I think it’s time to switch to ANA.
