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.

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.

Aircraft is new and toilets are spacious, but toilets are quite filthy. They should clean more often. They have a long list of drink offer but are actually not available during meal. They said they’ll come back with them and you don’t get them until after dinner which means you eat your meals without any drinks if you were to get something that they don’t have on the cart. They are strict about removing headphones during take off and landing which is new to us since the movies did not get turned off. Instead, we we’re forced to watch their commercials during that time. We probably would fly with them again but not with the cost we spent. For the record, I work in tourism and travel a lot for inspections.

Our transit in Taipei was disappointing. The ground crew could not tell us where the lounge was located, so we wasted 15 minutes trying to find it. The airline has a great review, but our experience says otherwise.

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 crews are very efficient. Other airlines should learn from them when it comes to boarding and departing from the airplane. They also display efficiency in serving meals. They don't keep the aisles blocked for hours like some other airlines. The food is poor. Generally the food was unrecognizable and poorly prepared. The only thing that made it better than US flag carriers is that there was a fresh fruit bowl with each meal.

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!

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

Great experienced staff and very pleasant compared to some other international airlines

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.

Flight was diverted to Osaka due to engine problems then arrived at a different airport 6 hours late. We were so tired. ANA did the best they could.

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.

Almost 6 hours of delay with over 12 gate changes. Flight was supposed to depart around 6 and instead depart after 12am. No accommodations were offered than some snacks closer to midnight when the crew was planning to throw away some snacks.
