Airline reviews

Has a major issue with my seat that I paid a premium price for. On the airline website, it showed the seat as the front row. In reality, there was another row in front of me. When I asked the company about it they told me that the front row was reserved for children with bassinets. On both the going and coming back, there were adults in the row in front of me. Coming back, there was a young child in the row to my right with a bassinet who cried constantly, so kept me awake during the long trip back. So I paid for a premium seat that was not premium! Needless to say I will not fly Starlux again.

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.

I liked the space of the bathroom. The seats were not as comfortable for such an expensive cost the the foot rest was broken. A small child cried for several hours and I thought the FA would have assisted the family to calm the child.

STARLUX Airlines has great staff and crew. Well organized for quick boarding of such a large plane out of Phoenix to Taipei. Interior of the aircraft was that of deluxe aircraft.

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 😫

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

Excellent. Airline was very clean, staff was excellent, very professional. Economy seats were still large and comfortable. Meals were included and with good options. We were given a blanket and pillow as well as a comfort kit including an eye mask, ear plugs, and tooth brush. Would highly recommend.

Business Class is exceptional, from the lie flat seats to the wide range of food on board. Can’t wait for our next journey with Starlux!

The staff in air and on land went above and beyond! I would definately recommend and we will fly Starlux again!

Serve me a meal, I fell asleep during the flight. So they passed me twice.
