Although the flight is listed as 17 1/2 hours, actual flight time was only 16 1/2. Bring a sleep mask to ensure you rest during your flight - it helps reduce so e of the flight time and helps you arrive more refreshed.

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.

Starlux is good, however the late boarding from Sea to PHL was frustrates. But it's nice for Alaska to owner the agreement with Starlux.

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!

Overall it’s good . However the food quality can be improved .

I purchased my two tickets on February 2025. Tickets were by each other, aisle and window. However, when we were boarded the assigned seats were one by the window and the other one in the middle of the four seated row. It was a horrible experience and we had to tolerate 17 hours of flight seating by different people. If the airline changes the seat arrangement, it should have the decency to notify the passengers in advance. I have checked my return tickets to Los Angeles, and I have noticed that they are not by each other and I don’t know what to do. I hope someone contacts me and rectify this mistake.

I had selected seats together for my family of three when I first booked my tickets in February. However, I realized only when I checked in at the airport that the seats I had selected were no longer assigned to us and we were completely scattered across three different middle seats instead of being seated together! After requesting the Singapore staff to have us seated together on a full flight, they managed to find something but it was right next to the rest rooms and the whole journey of 15+ hours was really unpleasant. They said that the seat selection isn't locked and the airline can reallocate the seats anytime. No one ever told us this and it was a terribly unpleasant surprise. Will avoid Kayak/underpricer and Singapore in future

The friendliness of the attendants, and the quality of the service.

Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

Very concerned with guest comforts going out of their way to accommodate special dietary needs when the guests hadn’t pre-ordered.

Clean modern comfortable. Food could have been better, I only ate breakfast I wish they wouldn’t wake sleeping passengers who would rather sleep through dinner. No tea or coffee for breakfast

Food was terrible , uncomfortable seats, WiFi did not work, will never fly Singapore again.

I had ordered vegetarian food. What I was presented was extremely dissatisfying and not up to the mark. I pretty much did not eat entire 19 hours. For.an airline voted as best in business, it was extremely disappointing. Seats were not comfortable to sleep. Entertainment system didn’t have much choice. WiFi didn’t work for more than half the time. Cabin crew were also difficult to understand. A bit of diversity like Emirates crew would go a long way.

A little more room from the reclining seat in the front of me.

They ran out of the second choice of food was stuck with fish

Seats needs to be wirer and food is very poor

Seats are uncomfortable and left me in pain in my tailbone area. I got about one hour of sleep.

Phx - ORD was nice 737 with starlink and the ORD - grr was ancient bare bones airbus with not even a power port lol

No white linens in premium economy . Salad was literally frozen. Food was terrible. No snacks. Ran out of food. I asked a flight attendant for snack on hour 8!of 16 hour flight and she said they don’t offer snacks and called me crazy for not having my own snacks for the flight.

It was easy to board, and the staff was friendly and helpful. What could have been better is that I shouldn't have to pay extra for a seat that doesn't recline.

Was on the plane sitting longer than the actual flight in air was, boarded at 5:45p and didn't take off until 6:50p flight was only about 30 minutes long. Just was poor experience will booking more with American Airlines.

Pretty much the exact same comments for this flight, there was crazy weather!

The guy in front of me was talking constantly, even when the pilot was making announcements. I found this very disrespectful to the pilot and to others.

The couple in front of me were constantly talking over the announcement from the captain and this was annoying me.

It was great. I really love the app. User friendly and very comprehensive when it comes to having information at my fingertips tips related my travel.

The plane was FREEZING COLD. Like I was wishing I'd brought gloves. Is this how JetBlue sells more blankets? Other than that, all fine. Crew just as nice as usual. A flight attendant asked (who? The pilot?) to have the air turned down for a great number of passengers who were as cold as I was. They (again -- who is "they") did not.

Flight was fine, but I was annoyed to have to pay for luggage again. We had paid for our luggage on our first two connecting flights with SATA Azores Airlines, but had to pay for luggage again with JetBlue at JFK airport. For one trip we paid over $500 for two suitcases to travel from Azores to San Francisco.

Everything was great the only issue was lack of Wi-Fi

Left a bit late duee to a technical issue, but got in early

Wonderful aircraft Crew was tired,but great considering On time No complaints

I am always very pleased with the service u receive from JetBlue employees

Your Jet Blue representative at the check in desk in Boston on Sunday morning, October 13, was unkind and unhelpful. For that reason alone I will avoid JetBlue airlines in the future. No food or beverage on the flight due to turbulence (not your fault). However I paid extra to sit in the upgraded section in the front and did not benefit from most amenities.

we used to fly with a different airline but it shut down. We had to find an alternative airline that we like in order to make domestic trips and this fits the bill. Not only is it a similar price but the customer service and the experience overall is much much better. We will be using JetBlue again.

Uncomfortable seat. No help for my disability. Staff refused to help me put my carry-on in the overhead bin. So I had to check the bag.

Terrible. Quality has gone down significantly. Plane was delayed. No instructions from the staff. Will try to avoid in the future!
