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

It did not feel like a luxury airline. We had booked premium economy and opted for AVML meals. This was one of the worst meal in any of the flights and I’m a frequent flyer. No great snack options were available. Drink selection was limited to wine and beer. On a long flight, you need a variety of food which was unfortunately not available. The seats were just OK and the foot rest are not comfortable.. Airline staff for courteous Audio and video section is extremely limited

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

amazing and great food. everything was smooth from start to finished

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?
