Counter personnel were friendly and professional. Assured me my bag would reach Bangkok without having to get it and recheck it for my international flight from Seattle. Also printed out all of my boarding passes for my trip.

Counter personnel were friendly and professional. Assured me my bag would reach Bangkok without having to get it and recheck it for my international flight from Seattle. Also printed out all of my boarding passes for my trip.

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.

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.

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 !?

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

Crew is very attentive. Another new airbus 350-900 plane. Very modern.

First time on Starlux. I was impressed. Very eager to assist flight crew
