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.

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.

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

Everything is smooth. Very good. Except flight arrived SFO 30min late.

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

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.

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

The aircraft is fairly new. The screen is big and it's great to enjoy movies on a long haul flight. However, the food quality , and drink and snack selections, have room for improvement.

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.

The crew are amazing. Very professional, polite, kind, and accommodating.

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.

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.

The flight who provided services on my row had some not-nice attitude and not smiling at all.

Comfort was left wanting due to such a long flight, made the wife and I wish we could upgrade the seats to Business class or First Class, but did not have that option. Food was good but had very limited options and I have a dietary restriction which was difficult for the staff to accommodate since everything provided came with cheese on it. (Cheese could potentially kill me) Did not have an option to inform the staff until we were already in the air about the restriction and was not provided another option before flight departed.

The plane was uncomfortable. I paid extra for more legroom but the seat was still uncomfortable. Other seats on the same exact row didn’t have to pay extra but still have extra legroom. I didn’t understand why I needed to pay $170 for. It was Iike China airline just wants to make money off their passengers. It was unfair.

Baggage made it successfully to destination despite short layover. Appreciate that.

Staff were good and nice. There should me 3 meals instead of only 2 and snacks.

Excellent staff made the boarding process fast and easy. Friendly crews on both flights from Saigon to Taipei and Taipei to Los Angeles. Will fly China Airlines again.

this is a great airline to fly on. I have not ever had a bad experiance with China Air.
