Exceptional performance and service. All staff members and crew members extremely polite. Great boarding experience from Taipei to Clark, loading passengers from rear of plane to the front. Only suggestion is to get people to curtail trying to so much as carry on.

Exceptional performance and service. All staff members and crew members extremely polite. Great boarding experience from Taipei to Clark, loading passengers from rear of plane to the front. Only suggestion is to get people to curtail trying to so much as carry on.

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.

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.

Customer service in Hanoi needs work, outside of that, everything was good.

Premium economy seats that I paid extra are not worthed.there was not much difference from the regular economy seats yet I paid alot more for it Disappointed

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 😫

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

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

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 !?

Other than spotty internet, great servic, comfortable and smooth flight!

I liked that they gave us a couple of meals and drinks but the meal was not good and not many options especially if we are seated in the back of the plane.

Crew was good. Sometimes food was eh. The spaghetti is gross for me. First time i got food, they didn’t provide utensils so i ate with my hands. I was hungry. They gave it to me 20 mins later when a crew member came by. I would fly with them again. Nobody is perfect

Eva air was fine - Trip.com via KAYAK sold my family access to a “VIP” lounge fo a layover in Taipei… i’m please look at my pictures. It was a scam, Trip.com knows it and they are perpetrating a fraud through your web site.

My flight was amazing smooth and the attendants were so friendly and nice

Crew are excellent. Food was good generally. Seats are small and there isn’t much leg room. Overhead bins are very small.

What could have been better, was we were delayed from takeoff for two hours. Initially we were informed that we were delayed for refueling. Then we taxied out on the tarmac, then just waited there for a long time, with no explanation of the delay. Were we just waiting on takeoff clearance or was there some other reason for the delay? The pilot, nor none of the crew informed us passengers. That was not good customer service. That needs to be improved, whenever a delay, inform the passengers for the reason.

More seat space More bathrooms Charging outlets Plane was old

This flight was long and I am so thankful I had a seat in the back of the plane. As I usually must get up and stretch every hour . The crew were probably the most friendly I have flown with. Thanks and I will book again with Eva air. Food was ok too.

It was a pleasure to fly with EVA airlines from Taipei to San Francisco.

Humm, I should have known that the seat I peaked on my flight from Inchon to Manila was designed for a toddler or very small person.

Felt like the oldest plane in Asiana Fleet. Screen was 5-6in only and no charging at all. Movie selection wasn't great.

When one asks for water because they are dehydrated, bring more then a sip or two in a small cup. Bring them a whole bottle.

Food could be better it was okay. Entertainment seems dated it was something but in this day and age could be a lot better.

I’d have rated Asiana good except an unfortunate incident in which I felt one of your employee didn’t really help us. During the first leg of the trip, the flight from LAX to ICN, I left my backpack on the plane. When I realized, I reported to one of your employee who promised me that it’d be taken care of, that my backpack will be there at HCM city. When we arrived there, HCM people had no idea and my backpack was still at Incheon airport who denied any knowledge whatsoever. I was left in the cold and felt helpless. I was very disappointed. I’d like someone to look into this and let me know.

I am thankful that I was able to fly using Asiana

2nd major delay due to maintenance issues. 1st delay missed my connecting flight.

It was great, but my bag was not loaded onto the connecting flight. I'm currently getting it resolved. If this isn't a problem, everything else was excellent.

Very clean ,flight attendants very professional,nice , Boarding was very easy

The aircraft was massive (A-380) and became crowded with 400+ passengers on board.

I thought the service was very nice and pleasant. There were no hiccups and no issues so overall a good experience.

Very good flight. Crew was great. No issues and we even arrived early.

The flights are constantly late anymore, and they won't even give you a glass of water on the plane. For years, they were able to do a service on this flight from Atlanta to Knoxville and Knoxville Atlanta now they say it's too short of a flight. You can't even get a quick drink of water.

Flight got canceled 4 times, missed my connecting flight due to delays, have to wait to go home tomorrow

Third flight in two months where the crew was not there. Comfort seating does not guarantee overhead bin space. Passengers with children are allowed on the plane first - if you are flying to and from Orlando, this means half the plane has boarded before you get on. And somehow all the bin space is taken up. 3 out of 5 flights have had issues with equipment or procedure. Some of these instances caused the flight to be delayed because of a "nuisance" light. One time it was a bag that had been brought on board but did not belong to anyone so we had to return to the gate. Last night we were told the "AC" on the plane doesn't work well and we're 10th for take off- because the crew was late - and that it will get cool when we're in the air. Not sure if this is usual, but I didn't think flight crew could jump seat in first class. Movie and TV selection has not been refreshed for several months- flying one to two round trips each month easily exhausts the list of content.

Great experience nice pilot very soft and easy landing and take off

We sat on the runway for over an hour before departure. That was unwelcome.

Horrible. Faucet in sink not working, wifi not working. Didn’t bring food or snacks

Flight was delayed before take off and at landing. Baggage took 20 minutes. Flight crew would not serve full soft drink and had to ask multiple times before receiving water.

From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.

Flight went very well. Cabin crew were all courteous and very helpful, always with smiles on their faces. Food was great. I always love heated nuts with wine. Flying business class with Philippine Airlines is always a pleasant experience.

It was amazing with great service. But the seating could have been better if there was ample arm rest areas

Flight attendants did very well, they were all friendly and very helpful .

Everything is ok except the manner of transporting the people that includes me on a wheelchair. That was my first time cuz I was suffering from “sciatica “ and couldn’t walk well. Upon arrival at LAX it took me almost 3 hrs to get out of the airport bcuz of these wheelchairs procedures. If only I can manage to walk I should have done so OMG. Other than that so far everything is ok. THANK YOU.

The check in staff were fantastic. So so helpful and nice.

Absolutely terrible. I will never fly that airline again. The problem was with the constant emails changing my seats, arrival/ departure times and the aircraft. The staff at the airports and onboard were great. Between making the appointment in May 2025 and my actual trip I had over 50 emails announcing changes. I was traveling with 3 other couples and they experienced the same thing.

Excellent service from check in/ bag drop counter staff to flight attendants. Food was great. Seats are nice. Excellent airline.

My luggages were lost and the service attendant was extremely unprofessional. Despite presenting my luggage claim slips, the attendant stated she had “no record” of my bags and made no meaningful effort to assist. When I explained that the luggage contained our family’s complete scuba diving equipment, her response was dismissive, stating that she “didn’t care.” While lost luggage is frustrating on its own, the lack of professionalism and lack of empathy significantly worsened the situation.

Flight was good took off on time arrived early. Crew was awesome and did a great job. Very helpful and courteous. Bags arrived super fast with no hassles. Great flight!!!!!!

Excellent! All flight related was memorable ! My first experience with Mabuhay Lounge,,, not so good
