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.

Excess baggage fees are outrageous ($250 per bag). Flight crew and planes are nice.

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.

Service in BKK was very good at answering our question about our canceled flight from Taipei to San Francisco. Did like the lead time about the canceled flight from Taipei to San Francisco and was not given the best options.

Staff show very stress with delayed flight more than passenger.

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!

Very bad. They don’t allow group people to sit together by blocking most of seats and opening only single seat during online checking in. . By doing so, they can rip off customers at the check-in counter by collecting extra money if we want to sit together in the same row.

Delayed. Not a full flight and whole rows left open with the paid seating. Food was ok. My beef meal only had one cube of beef the rest carrot cubes. Entertainment on personal device but didn’t know about it until the flight was almost done.

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

The flat bed full lying position is not comfortable at all, this could be improved, it is at an awkward position which i dont have the same issues with other airlines business class.

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.

I absolutely loved my flight from Taipei to LAX. I was originally assigned to a different seat, however one of the stewardess noticed I was uncomfortable in my seat. She offered to move me to a more comfortable setting. Although she didn’t have to do what she did, I am more than grateful and thankful for her doing so. My longer flight felt much more comfortable, just by her taking notice. I really appreciate her.

Overall was a lovely experience. The crew were kind and courteous throughout the entire flight.

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

They need to improve on how the plane lands cause it was not smooth at all.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

No lunch on a x-country flight scheduled for 10:50 am departure, arrived 5+ hrs later. That requires a black box label before you pay for the tickets. Worst, when I checked in online, it's specifically said that lunch was served on his flight for economy Plus passengers.

We had a lot of really rough weather but that was not Delta's fault. Pilot was amazing.

One of the best airlines that I flew on, the flight attendants were very attentive and professional.

The flight attendant on Korean airline was a super nice. it’s one of the best over-sea airline I flew so far.

First, Delta needs more flights to/from Miami. Second, a 1000pm leaving at 1230pm is unacceptable from their biggest airport world hub. Another aircraft could have been used such as the aircraft scheduled to be used in the morning for that exact same route. Yes, I did get me there but the lack of sleep the next day didn't help me enjoy my entire trip since I was busy with activities during the weekend. This can be and is expected from Spirit (going bankrupt) and Frontier (despite they're nickel and dimers). But from Delta's World Hub? That's totally unacceptable!

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!!!!!!

Many movies do not have captions, which would have been helpful when you have to live with the flight engine noise.

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

Everything was fantastic!!!! I can’t wait to fly home 😃!!!!!

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

Flight was really good, considering the semi bad weather in MNL. Food was great. Crew kept offering throughout the flight. Wifi signal was intermittent though.

It’s sad how legacy airlines feel like budget airlines now. Cramped space Non reclining seats No inflight entertainment (need to connect via your own device) Saving grace is the crew. Truly nice and sincere service.

You have to pay $25 to get access to smoking lounge. One coffee and small bottle of water coupon provided. Max time 2 hrs for two entries total.

Crew excellent calling me by name ! Only downside was no inflight WiFi

reach the standard, crew tried to fix up issues fast.
