more new movies and the blockbuster movies that everyone likes

Great airline. Kind staff, before m, during, and after the flight. They Directed you the whole way. Even when I arrived at my transfer destination, flight attendants guided passengers on which direction to go. I would definitely fly STARLUX again.

Got dinner and breakfast! They had mahjong game in entertainment system. Current movies. Loved the slippers, sleeping mask packet. Great experience for a long flight

Leg room was great. Friendly crew. Food is great. Crew always kept the toilet clean.

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.

Th tray was dirty when pulled it out. Still oily and food stains can clearly see last trip cleaner did not clean well. The toilet sink water did not drain quickly enough.

Majority of the movie entertainment loaded in the aircraft were quite old.

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

Passengers were confused and freaking out coz the flight information wasn’t showing on the board that was running with all the departing flights. B9 gate was still showing Cathay Pacific bound for HK 15:50 was on until 22:07. STARLUX staff cameater but didn’t let the passengers go in to pre departure area until 22:45 for the 23:30 boarding time
