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.

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.

Has a major issue with my seat that I paid a premium price for. On the airline website, it showed the seat as the front row. In reality, there was another row in front of me. When I asked the company about it they told me that the front row was reserved for children with bassinets. On both the going and coming back, there were adults in the row in front of me. Coming back, there was a young child in the row to my right with a bassinet who cried constantly, so kept me awake during the long trip back. So I paid for a premium seat that was not premium! Needless to say I will not fly Starlux again.

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.

I liked the space of the bathroom. The seats were not as comfortable for such an expensive cost the the foot rest was broken. A small child cried for several hours and I thought the FA would have assisted the family to calm the child.

STARLUX Airlines has great staff and crew. Well organized for quick boarding of such a large plane out of Phoenix to Taipei. Interior of the aircraft was that of deluxe aircraft.

Hostesses were very nice I am disappointed that I paid extra 900$for premium economy which wasn't much upgraded from regular economy, I have wasted my money on this trip 😫

love this boutique luxury airline. crew was nice and attentive. Lounge is too small , i think they should have more area for relaxing and lounging not just to sit and eat .. feels like a cafeteria more than a lounge. overall i enjoy it. food on the plane LAX to Teipei should inprove a bit. no flavor and more drinks pls

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!

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

I wish there was water passes around. Long Flights with no water Except at the beginning

We were not sat together for the longeset duration of our travel very uncomfortable didnt enjoy that they fed us at 2 am

Flight attendants. Food, entertainment and most of all, be on time.

We are glad to have used China Airlines for our trip. Continue the good service! Thank you!

The flight was uneventful and the crew was kind and professional. Really appreciate the option to order a vegan meal for the flight!

I love my Delta crew, they were so welcoming and helpful.

Better organization of boarding procedures. Terrible leadership guiding people to gates.

I did not like how the plane landed. It was not smooth.

China Airlines crews are very excellent doing their job. Very friendly and hardworking. I will always choose China Airlines over and over. Thank you all for making my flight comfortable. God bless to all the staff. :)

I don’t think I’ll be flying them again. Tight seats, no flowing air or air nozzles that you can turn air on you, for those who could have motion sickness this would be your worst nightmare. The pilot was great and experienced (which is what you want when flying 12 hours) overall I’m thankful knowledgeable pilots!

I purchased my two tickets on February 2025. Tickets were by each other, aisle and window. However, when we were boarded the assigned seats were one by the window and the other one in the middle of the four seated row. It was a horrible experience and we had to tolerate 17 hours of flight seating by different people. If the airline changes the seat arrangement, it should have the decency to notify the passengers in advance. I have checked my return tickets to Los Angeles, and I have noticed that they are not by each other and I don’t know what to do. I hope someone contacts me and rectify this mistake.

I had selected seats together for my family of three when I first booked my tickets in February. However, I realized only when I checked in at the airport that the seats I had selected were no longer assigned to us and we were completely scattered across three different middle seats instead of being seated together! After requesting the Singapore staff to have us seated together on a full flight, they managed to find something but it was right next to the rest rooms and the whole journey of 15+ hours was really unpleasant. They said that the seat selection isn't locked and the airline can reallocate the seats anytime. No one ever told us this and it was a terribly unpleasant surprise. Will avoid Kayak/underpricer and Singapore in future

Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

Very concerned with guest comforts going out of their way to accommodate special dietary needs when the guests hadn’t pre-ordered.

I had ordered vegetarian food. What I was presented was extremely dissatisfying and not up to the mark. I pretty much did not eat entire 19 hours. For.an airline voted as best in business, it was extremely disappointing. Seats were not comfortable to sleep. Entertainment system didn’t have much choice. WiFi didn’t work for more than half the time. Cabin crew were also difficult to understand. A bit of diversity like Emirates crew would go a long way.

A little more room from the reclining seat in the front of me.

I wish there was a little more leg room between the seats. The recline was good and seats overall were comfortable. I also didn’t like the 2-4-2 configuration.

toilets could be cleaned more frequently, everything else was pretty good.

Wish the underseat compartment don’t have a restriction, can fit a personal item such as backpack fully like most Boeing

Crew and service excellent. 2 hour delay for takeoff. SQ app showed flight on time.

Phx - ORD was nice 737 with starlink and the ORD - grr was ancient bare bones airbus with not even a power port lol

Even though the incoming flight was delayed by 20 minutes they managed to get us to SFO 15 minutes early.

Gluten free snack options and meals that offer both gluten free and dairy free.

First class ticket gets you no seat back entertainment? I have to bring my own laptop to see a movie? And most of their movies have ADS? No thank you. Worse: Tiny snacks only on a 2 hr flight?

We purchase first class seats for the first time for multiples of standard economy ticket. There was no access to the club lounge and no priority boarding. The meal and the service once on the plane were superior and the seat was nicer, but not worth the price difference. I will be happy to seat in economy and spend the difference on more travel.

I upgraded my seat and was promised it would be next to the emergency door for extra leg room and they said it was premium plus but it was at the back of the plane...same thing happened from Newark to Dubai

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.

The woman gate agent in Phoenix was none too sympathetic about my check-in process as I am relatively new with using apps. I almost did not get on because she said I did not check-in. I thought I had via Kayak where I purchased a very expensive ticket. Lesson learned but to be told I may not get on as a matter of factly was difficult to hear.

We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again

Check-in was a nightmare. Wouldn’t let us board with our dog even though he has flown on anir Canada before. Only one of us could go. Will never fly them again.

Over 40 years ago my AC return flight was canceled, during this last summer the same thing happened. AC denied everything Canadian like paying for accommodations and basic necessities. So why would I ever want to fly AC again? This last flight my wife took the return flight had problems and left late, so I guess they are getting better. However I have no faith in this airline so I drove to this last destination! I'll never fly AC again!!!

Didn’t realize I purchased a basic fare with no carry ons allowed. Not very well communicated. Also had seats switched without knowledge and had to pay for different ones.

They canceled my flight and then refused to reschedule me on another flight. I had to take a train. No compensation. I won't use Air Canada again.

Staff was friendly helpful also good timing I rate it a 10 out of 10

it was red eye flight, it was ok, there was beverage service, thats it i didnt care much as i wanted to sleep

The TSA agents in Phoenix were incredibly rude and confiscated belongings that we wanted to check. The flight got changed without our knowledge to a worse situation. The whole thing was terrible

First, When I check in at Phx air Canada counter, I couldn’t make it myself, either at the check in counter, the lady told me that I need a Canada visa to take this plane, then I told her that I have a lots of friends go back to China and transfer in Canada, I’ve never heard they say they needed a visa to stay in the airport, also, I have US lawful green card, as I did research, I knew all U.S. green card holders don’t need a visa to go to Canada if stay a short time. And then they agent lady asked her workmates, spent over an hour then finally have the boarding passes for me. Secondly, my flight is from Phoenix to Hongkong, one stop at Vancouver, but I had to get my bag in Vancouver then re-check in again there. I asked them, they told me that because my layover time is too long (about 20 hours), so they can’t do bags check through. I understand this, just compared with other airlines I travel before, this isn’t a good experience to me.

There was no entertainment and the meal that was included in my flight fee was not provided.

Well is extremely poor, not even a small bottle with water. Completely different than what use to be in 1970. Evolution or devolution? Everything those days is just make money, but not to remain with a nice experience, on pillows, no blanket's, no nothing!!! , Excellent pilots. But service from service, zero.
