I went to the gate that showed on the flight board but they changed gates at the last minute and I missed my flight. I had to buy new ticket from EVA air to Manila and take 3 hour bus ride back to my home. Will never fly Starlux again!

I went to the gate that showed on the flight board but they changed gates at the last minute and I missed my flight. I had to buy new ticket from EVA air to Manila and take 3 hour bus ride back to my home. Will never fly Starlux again!

Starlux was great service and awesome food and drinks👍🏼 will take starlux again for my next vacation👍🏼

Loved the boarding process. All airlines should board from the back to the front. Very efficient. Food was excellent, crew were great, seats were spacious and comfortable and the entertainment screen was the best I have seen.

Flight cancelled due to inclement weather yet rival airline EVA Air with the same route departed 2 hours later and landed safely while our flight was cancelled and rescheduled for 36 hours later.

The staff in air and on land went above and beyond! I would definately recommend and we will fly Starlux again!

I need Starlux to respond to my complaint and issues for my flight.

Someon vomit during boarding. My seat was next to the vomit. I asked crew member to switch seat, but they said it was a full flight. I had my baby with me. My baby got sick after the flight. He was in the hospital for 2 days.

The airplane so clean and they have a nice crew

it they come out with resent movie and good food

The crew could have been kinder and less pushy. The premium economy seats don't have enough cushion. The seats are to hard and the flight became painful and uncomfortable after an hour of flying.

Everything was great, however the seats in the back are very small. Not as Comfortable as I would have liked.

Eva airlines has very goin service, despite being low cost. Meals and fin, not amazing, restrooms always clean and staff polite and helpful

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

The crew very accommodating and food too is good. Keep up the good work

Flight was canceled was only given only a 8 hour lead time. Had to fight to be put on another airline (United Airlines) that was leaving earlier then the one EVA and rescheduled.

The EVA air staff at Narita did a terrible job with signage and communication. Despite getting to the airport hours before, they had me queue in line and did not communicate that passengers for Kaohsiung need to step out of line to go to a different line. If you put the flight number at the front of the line, people will think that’s their line. If your staff walk silently down the line with a sign of the flight number, how are we supposed to know you want us to follow unless you speak or write that? I even asked the staff with this sign when we could check our bags and they assumed I was on the later flight to Taipei. Later, Wl only 30 minutes remaining I called for help, and the staff looked at me like I was in the wrong. I had to rush through security and customs and had no time to eat or buy a gift. I’m deeply disappointed in the way they handled it, and it caused unnecessary stress on my vacation.

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

EVA airlines was excellent: on time or early, safe, courteous crew. Highly recommended.

EVA! What is going on with your food!?!? Pre pandemic I used to go to Taiwan at least twice a year and always flew EVA — the food was consistently tasty for airplane food. Post pandemic, it’s not great at all. Step it up!

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.

Although the flight was delayed because of the equipment came in late, I still give them excellent service ..good food selection and in flight entertainment were sufficient.. I will continue to fly with them

Staff was rude and loud. No respect for customers unlike the Starflyer Osaka to Haneda sector where service was outstanding. What a stark difference. Maybe United should learn from ANA how to do customer service.

The meals were sufficient and tasty considering it was air travel food. Water coffee and juices offered each time a meal came by and water distributed between meals. It was good service in my opinion. Plenty of movies to enjoy. May not be the one you want but plenty of older movies and plenty of current ones as well. I enjoyed the trip.

The crew was incredible. The pilots were so fantastic. The smoothest landing I’ve ever experienced.

The flight attendants are always fantastic. My only issue – and it was on my Haneda to Vancouver flight – same as my Vancouver to Osaka flight – I had a confirmed special meal and they had no record of it on board. I tried to confirm it with the gate agent in Fukuoka, where I initiated the day, because of the mess up a month ago, and she said that they can't confirm special meals. I'd have to see when I got on board.

Great transfer of luggage from my flight with Osaka to Tokyo then Tokyo to final destination in Chicago

we were in premium economy, but we both got middle seats and had to sit separately. i could have avoided this by trying to obtain seats sooner, but i tried 3 times and gave up. ANA's technology is not friendly for newcomers. no, check that---I think it is nigh impossible. not sure we are coming back. ana can do better to provide a front end that's friendly to users in both US and Japan.

Checking in via an alliance partner, even a foreign one should get TSA Precheck printed on your boarding pass. The paper copy issued by ANA didn’t show it. I couldn’t get my digital copy due to some technical issue arising because I checked in with ANA. The kiosks at SFO similarly threw an error. The only way I could have gotten a new copy of my boarding pass was from the UA counter and lines were nearly as long as TSA so I bit the bullet and went through the regular TSA line. If UA wants my business, they need to improve that process.

Great as can be expected with a 10 hour flight over the Pacific. Great movie selection of new releases that hadn’t hit streaming yet. And despite the bad rep, I actually like the airplane good.

One of the best business class seats I’ve had. The lie flat seats made it comfortable to endure a 12 hour flight. Service was excellent and food was great.
