Preboarding food selection is an excellent idea. On the other end I did know the choice. People in my area know the choice. It ends with I got my meal till most of them are half way to finish their meal.

Preboarding food selection is an excellent idea. On the other end I did know the choice. People in my area know the choice. It ends with I got my meal till most of them are half way to finish their meal.

Overall it’s good . However the food quality can be improved .

My luggage was forced open and broke the zipper. I received it in a huge STARLUX plastic bag. Unfortunately, I have a round trip ticket but might be my first and last with this airline

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.

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😊

Although the flight was slightly delayed, it was well communicated with the passengers. The staff are all nice and accommodating, the pilot are very good. I didn’t realize that the plane was on the ground already. It landed smoothly. I’ll for surely recommend EVA Air to my friends.

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.

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.

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.

Hour late but understandable under the conditions. Taoyuan airport could have clearer signs language wise and more staff to help direct people.

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 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.

Sat next to a woman who had her period. Blood was on her seat and on the arm rest between us. I ended up having period blood on my jacket and shoes. Very gross!

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

I did not like how the plane landed. It was not smooth.

The flight was delayed for about 2 hrs. Other than it, it was good.

Advertised fruit trays with cheese, but only snacks handed out!

The plant way delayed departing by 3 hours. It was an old airplane with broken seats and armrests. The bathroom made a hollering sound. A really crappy flight experience and travel day all around.

Premium economy is like the forgotten class. Aside from meal service never saw a flight attendant. Any additional beverages required going to the very back of the plane to request and there was rarely an attendant there. Seat leg / foot rest hardly elevates and not well suite for someone under 5’6. Bulky armrests

Flight delays both to Detroits and return flight . The flight to Detroit was associated with mechanical difficulty

Flight was operated by Virgin Atlantic and it was up to their usual high standard. Minor grips about some issues, but they are really first world issues and as a whole, was an excellent flight.

I am extremely disappointed that delta internal pilot manuals now refer to the Gulf of Mexico as the “gulf of America”. You can bow down to the Orange turd on your own. I will never fly delta again

Delta One upgrade it would have been great if my tray extended (it was jammed and wouldn’t pull out), seatbelt had too much slack & my little cabin door didn’t close properly

I paid for a business class ticket on Delta. It was sourced to Virgin Atlantic. They changed out the aircraft which had fewer upper class tickets. Even though I'd checked into the lounge, was receiving alerts via kayak about the delay and changes; no one informed me that the seat would be changed - until I attempted to board and was told that I would have an economy seat or they could search to put me on another airline. Even the flight crew were informed of this change (10 passengers were bumped out of Upper Class) around 2 pm (1400) time. Hours would have helped to consider alternatives instead of making a last minute change. There needs to be compensation from both Delta and Virgin given this change in service/experience.

Wasn't a Delta issue I don't think, but seems there was a Delta flight at each of the 2 Dallas airports at the same exact time, both to Atlanta. I was evidently booked on the one at Love Airport, but the Carey transport shuttle took me to DFW instead and I ended up missing the flight by just a few minutes. Was able to book a Southwest flight from Love Airport, but was a big loss of time and an inconvenience.

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

Plane are getting old, almost an hour delay due to technical reson , after all passenger aboard. Took 4 flight on business class this trip and all the planes had an issues. PAL need to improve their planes.

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.

It was great! The flight was on time and had a smoother flight

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.

Everything was very good but seats are small for a big man!
