The Singapore Changi airport if huge. After getting of the aircraft, the walk to immigration control was long. Once you get to the control area, the process was quick and easy.

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.

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!

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

I love the comfortable business class seats. The service was excellent. Staff was friendly.

when i ask for help all the crew members had a look like why are you calling me? very terse and rude.

Good service and food. However, we paid over $400 for aisle seats for my disabled husband and me, and we were given window and middle seats. This was dangerous for our health condition on such a long flight. We needed to stand up and walk around frequently, but we were stuck in our seats. Please give us a refund of our seat payment since you chose not to honor our request.

Selected ovo lacto meal because I’m ok with milk products but not any meat. It was terrible. We had the same selection back in October when we had traveled and it was pretty good at that time. It was gross this time.

Very bad Instead 22 hour it take me more that 35 hour to arrive from Los Angeles to Phuket and they changed my flight in Hong Kong to Shanghai china and in order to get my bag I was forced to vet china visa entrry

There could have been more options on the entertainment section Nothing was available for non English speaking passengers

We flew economy light. We did not want to check bags and we had free 1 bag, but just had back packs with small personal item. Try as we may could only get bags down to 17lbs each. So we put 2 lbs from one bag into other and checked it. I think if someone has a checked bag allowance and chose not to use it , it would benefit both parties to bump carry on weight up to the next level of 22lbs or 10kgs. Just a thought.

I didn't have much experience with Cathay Pacific airlines because of delay and missed connections, the bulk of the trip was on Japan Airlines.

Flight delayed first from bad weather, then after boarding there was a problem with the plane. We had to get off and onto another plane...connections were missed and the trip took an additional 10 hours!! Pre-paid seatting was not honored due ro last minute carrier changes. Most of the trip was on Japan Airline.

The bed was alright in business class. Food variety and quality were not up to the mark compared to the business class airfare.

Check in process was excellent. Lounge needs improvement. Food not palatable and no good choices.

It was never explained why the departure flight was canceled and delayed for 1.5 hours. It would have been nice to stick with the original itinerary.

A shameful national carrier. Service has gone down from the highs of a decade before. You don’t feel the Filipino hospitality. It’s an aging fleet. Nil comfort, and I flew premium economy.

Many movies do not have captions, which would have been helpful when you have to live with the flight engine noise.

Everything was fantastic!!!! I can’t wait to fly home 😃!!!!!

Plane are getting old, almost an hour delay due to technical reson , after all passenger aboard. Took 4 flight on business class this trip and all the planes had an issues. PAL need to improve their planes.

Food could of been better. Crew was pretty much average. It was raining a lot on arrival, had to take a bus to immigration building,

You have to pay $25 to get access to smoking lounge. One coffee and small bottle of water coupon provided. Max time 2 hrs for two entries total.

I was glad that the plane was not totally full.

Well, I needed to make a change to my flight and I called the airline and they said yes no problem $700 and we can do that and I agreed to it so they canceled my tickets and went to rebook and came back after being on hold for an hour and a half and said I’m sorry, sir. There was an error. It is $2800 Now and I said never mind. I will just use those flights and she proceeded to tell me that they already canceled them because I said I was interested in doing the change. I told her yes for $700. I was fine with doing a change but not $2800 so give me my tickets back and she proceeded to tell me that she could not do that and I had to pay the $2800 to get my tickets back that I already spent $2800 on. So I had to book tickets on another airline to get home And that cost a lot of money too. I’m a little pissed off at Philippine airline right now because of what they did to me and I’m not sure I ever wanna fly with them again. I’ve flown with them plenty in the past, but this just really put a bad taste in my mouth.. Not to mention on my way there leaving Seattle going to Vancouver. I got to the airport three hours in advance and they had booked me through Alaska Airlines to do that little trip. My connecting flight would leave about six hours after I got to Vancouver BC. I stood in Alaska Airlines lying for a little over two hours and then they proceeded to tell me that they couldn’t check me in because I wasn’t there an hour in advance. I kept telling the lady at the beginning of the line that I was afraid they were not gonna let me in because it was taking so long and she said oh don’t worry about it. You’re fine you’ve got time. Well I ended up spending $600 to get to Canada that night just to make my connecting flight because Alaska air wouldn’t do anything and Filipino Air told me it was Alaska air problem but Alaska air said since you booked through Philippine air, we can’t fix it. I had about 50 minutes to make my flight, but they refused to check me in because I wasn’t there an hour in advance yet. I’ve been standing in their line for about two hours and 15 minutes.
