Excellent. Airline was very clean, staff was excellent, very professional. Economy seats were still large and comfortable. Meals were included and with good options. We were given a blanket and pillow as well as a comfort kit including an eye mask, ear plugs, and tooth brush. Would highly recommend.

Excellent. Airline was very clean, staff was excellent, very professional. Economy seats were still large and comfortable. Meals were included and with good options. We were given a blanket and pillow as well as a comfort kit including an eye mask, ear plugs, and tooth brush. Would highly recommend.

Business Class is exceptional, from the lie flat seats to the wide range of food on board. Can’t wait for our next journey with Starlux!

Th tray was dirty when pulled it out. Still oily and food stains can clearly see last trip cleaner did not clean well. The toilet sink water did not drain quickly enough.

Majority of the movie entertainment loaded in the aircraft were quite old.

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

Passengers were confused and freaking out coz the flight information wasn’t showing on the board that was running with all the departing flights. B9 gate was still showing Cathay Pacific bound for HK 15:50 was on until 22:07. STARLUX staff cameater but didn’t let the passengers go in to pre departure area until 22:45 for the 23:30 boarding time

The aircraft is fairly new. The screen is big and it's great to enjoy movies on a long haul flight. However, the food quality , and drink and snack selections, have room for improvement.

Preboarding food selection is an excellent idea. On the other end I did know the choice. People in my area know the choice. It ends with I got my meal till most of them are half way to finish their meal.

Overall it’s good . However the food quality can be improved .

My luggage was forced open and broke the zipper. I received it in a huge STARLUX plastic bag. Unfortunately, I have a round trip ticket but might be my first and last with this airline

American Airlines Business Class does not meet the standard it should when compared with Japan Airlines, Qatar Airways, or Air France. The flight attendants often appear disengaged and fatigued, with forced smiles, noticeable attitude, and occasional rudeness. Food options are subpar, the overall ambiance feels cheap and outdated, and the cabin design reflects a past era rather than current premium expectations. Lastly, the aircraft itself felt old and uncomfortable. Overall, the experience is not competitive with what peer airlines are offering today.

This was serviced by American Airlines. Not as great as Japan Airlines. The LAX domestic airport is not a great airport. We needed to take a shuttle to go to the gate. Mind you, this is just a connection, but we had to go to security again, which is a hassle after a very long flight from Japan. It makes sense, for our checked baggage to be picked up and moved to the other carousel for our final destination, but for us doing the security all over again, pointless. We had our boarding passes already when we were still in Japan, yet we had to start from zero again when we arrived LAX. There should at least be a different line for connecting passengers without going out like it’s our final destination. Next time, I will try to book our flights from any foreign countries non stop to my destination.

I really love their services! From checking-in to deplaning, superb! Highly recommended!

The flights were on time and the cabin crew were very nice. The only downside was that the food was not good

I like the intention and service of the flight crew. Japanese values were observed and appreciated as a customer.

Our flight was delayed by one hour. Luckily, we were still able to make our connection. This flight is really an Alaska Airlines flight and not the same excellent service and comfort as Japan Airlines.

Very comfortab flight. The flight crew and service was terrific. The food was average at best.

First time flying. Very comfortable, plenty of leg room in economy. The food was good, as well as the snacks. Quick flight back from Kansai to HNL.

Excellent service, excellent food and beverage options, plenty of legroom

I wouldn’t know, I tried to contact you days before to reschedule my flight back to Okinawa but you left me on hold for 2 hours. I tried calling multiple times and not once did you pick up. I had to spend 2000 dollars on a one way ticket back to Okinawa because I couldn’t get ahold of you guys to change my flight.

Both of my flights arrived early and check in process was smooth

Everything was on time Will use united again for sure

I just think it’s unfortunate that Airlines have completely abandoned the idea of serving any kind of decent or even real food on flights, not even on a four hour flight!? Those days are gone, I guess.

The flight was delayed by two de-icings. The seatbelt did not work correctly. It did not stay tight.

Hotter than Hades in August. Why, why do crews think that in the winter when we are already dressed for cold weather we need a cabin that is 82 degrees. Even the vents were blowing hot air.

Flight was delayed. De-icing took a while. When we landed had to wait for another plane to vacate our gate. Just an overall bad experience.

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

United have really come back. Airport and boarding process is clear and good, app and information also very good

We Left Calgary 1/2 hour late and that made for a tight connection in Denver. After arriving everything was done to help us make our connection. That was a great effort. Thank You United

The entertainment available didn’t work for anyone on the flight. Long 6 hr flight with no entertainment option and the staff didn’t know until an hour into the flight when we made sure they knew about it. They had no way to fix it.

they were super helpful. Agents at the desk got me on an earlier flight and I was able to get home several hours earlier.

This is a great non-stop YVR-MIA. Very comfortable plane, and no transfer through a city that gets major winter weather!

Terrible…. Reported missing luggage’s with injectable meds that needed refrigeration. Yet, delivery could not be expedited. Luggage’s were delivered 5 days after arrival. The meds were useless as ice pack had melted. So disappointed!!!

Air Canada’s problems are not staff related by and large, no. The problem is tiny jets between the U.S. and Canada - yes, believe it or not they are still “international” (just ask our own Mango Maniac in power in the U.S.). The little aisle is compounded by a design flaw of a “dog leg” starting at seat 12. Woe be unto you if you sit here as passengers and attendants do not have sufficient room to not hit you in the face with backpacks. One thing I will say very positively about Air Canada is you still provide pillows and blankets on transcontinental flights to all, not just the elites. Your tiny improperly designed jets are also a problem flying city to city within Canada also. One can only say you remind us of a “Jet Blue” or “Spirit” experience. Also your luggage space is downright Byzantine! We will endeavor to avoid you and use other U.S. carriers, albeit charging more.

Terrible canceled flight and lost my luggage. Flew me to Halifax. Tgat flight was delayed, had to spend night in airport chair.

Better entertainment & food options more may be adding chicken option or on vegetarian side good quality pasta

My seat was not comfortable. Flight was smooth. Regretfully we had two delays before takeoff

Amazing service, with enthusiastic crew members, and some breathtaking views of Vancouver. No IFE though, as it is only a 1 hour flight on a regional Turboprop jet.

The cabin crew was professional and there were plenty of movie choices, but the food was a bit sub-standard.

Wifi was great. Kind air crew and comfortable seating. Also liked the entertainment options.
