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 !?

We are on economy premium but they put us in economy seating? Asking why the fligh supports said : If you not happy you can claim for refund?

FLEW IN BUSINESS CLASS OVER NIGHT FLIGHT AIRLINE BOOKED A PARENT AND ONE YEAR OLD KID PARENT ALLOWED THE KID TO DISTURB EVERYONES SLEEP A terrible flight that was expensive I have 10 grand children I love kids But to be disturbed on a over night flight is in not what I paid for I hold the air line responsible Respectfully, Al Eaddy

I liked everything but I flew business class and StarLux booked another passenger and a one year old , in business class The child cried 80 percent of the flight, the flight was a long 13 hour flight. I’m 75 and I have 10 grand children, I love kids But with that said it still made it not and enjoyable flight. Ask your great flight attendance what they think of the situation, they had to deal with. Let me know what they said Respectfully, Al Eaddy

Everything is smooth. Very good. Except flight arrived SFO 30min late.

more new movies and the blockbuster movies that everyone likes

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.

Kayak along with airfare assay are attempting to steal my money. Charges are being pressed.

Customer service and attention to details. The food was good.

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

The customer service was excellent. They noticed that our connecting flight was scheduled too closely for us to complete customs, so they changed the flight. Our initial flight was delayed, and they were able to get us on another flight, all without charging us any additional fees. I would fly them again anytime!

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.

The plane hasnt left im stuck in seatle still my flight has been grounded for almost 5 hours

If you cant travel Delta One, Comfort Class is the next best thing!

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

The seats were really comfortable. Flight crew were friendly with passengers. Overall was a great flight.

Arrived early, comfortable seats (Comfort+). Mediocre food, poor wifi (intermittent).

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Flight was great! This flight from Atlanta was even better than when I paid for Comfort from SNA to Atlanta.

Great crew, flight on time, luggage pick up a breeze

Was on time, normal boarding. The worst flight attendents and service I ever seen,, can't believe Delta can have such service. Bathroom was dirty and no toilet paper, paper towels and used toilet paper all over the floor, when I tried to tell flight attendant she didn't even let me to finish and turn around. Very rude. Wi fi didn't work.

Connection flights should be spaced out farther because too close I missed my connection.

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.

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!!!!!!

A shameful national carrier. Service has gone down from the highs of a decade before. You don’t feel the Filipino hospitality. It’s an aging fleet. Nil comfort, and I flew premium economy.

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

Great. Always great service and their pilots know how to land planes properly
