Pack a hoodie and wear pants. Don't purchase anything past initial security check- youll have to empty any drink- even a sealed cola can- before getting through a secondary screening at your gate.

GordonFlew with United Airlines-Apr 2024
Check your all or most of your luggage if you can. Take a small light carry for your must have items with you such as snacks, book and electronics on hand accessible during the flight.
SoukindaFlew with Singapore Airlines-Feb 2024
Bring a sweater, a mask and wear socks. Although they provided a blanket, it’s very chilly on a long flight. I caught a nasty cold from the flight and wasn’t masked up. Other than that our flight was great and comfortable.

The staff was great. I also like the movie selection was great. Lastly, it I appreciated the fact that wine was a drink selection.

The quality and the quantity of food was terrible. I was starving to death at the end of the flight. Used serve 3 meals long time ago, now reduced to 2 meals during the 17 hours flight. Never offered wine or tea to us. We have to ask . Extremely hard to get the attention of the flight attendants. They intentionally ignore us to minimize the service. Bathrooms were dirty

Never book through Kayak. They can offload booking to third parties that are completely horrible.

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

Everything was good except food , food choices was very less. Washrooms were closed.overall good experience.

When boarding, after business class should be premium economy, but economy class already lined-up at the gate blocking premium economy to board. Singapore airline crew should done a better job to organize this chaos :( Thank you.

They were able to assist my elderly father and myself after not being able to check in to scoot. The counter service was phenomenal. They did what they could to get us on the next plane so we could catch our Connecting flight. Scoot closed early on us so we ended up missing our flight.

They are great with every aspect of customer service. Helped my elderly father and aided him with using the restroom.

Excellent customer service from pre boarding to the end. Really enjoyed my flight. Very helpful crews during flight as well. Will definitely flight with Singapore airlines again.

Food quality and serving frequency was poor. Travel kit was not provided. Flight was very bumpy. Overall, not a good experience.

They overbooked the flight and reassigned my seat. To add insult they lied that my assigned seat was broken and promptly gave it to someone else

Jain veg meal I opted was super in taste but there was no sweet/desserts with it. I was a big missing in the meal...Please add some sweets to end the meal with 😊

I’ve flown 2 better Asian airlines in the past year.

Seat is too small. Food selection is limited and often ran out of selectable item.

The worst experience ever! Lots of flight delays and rerouting that ended up doubling the total time. . I had to recheck my luggage because I was rerouted to Tokyo and ended up on ANA flight. I missed connecting flight twice because of the delay at Cathy Pacific. Additional stop added, rerouted to a different country for connecting flight and ended up in long waits and delays.

My only suggestion is a way to not be woken up for food. … like maybe something you can place on you if you’d prefer to miss food than be woken up

I wish there were more bathrooms available on these larger carriers.

Not much of anything could have been done better unless I had a first class ticket. I was literally 15 hours with an airline in the economy class. Very professional friendly and attentive crew. Good airline food, clean cabin, seating area and bathrooms. I've been 4 times back-and-forth with Cathay Pacific, and I would not choose another airline for this trip. Five out of five stars.

Special request meals are really below average. Vegetarian options are very limited if you didn't prebook.

Horrible. No good food. Baggage missed to onboard and came after a day. No support to compensate the delay. Customer care cannot see the status of the complaint. No reply of the email.

Terrible flight attendant. Rushing me as I ate my salad and appetizer. Served my dinner while I was still eating my salad. My dinner was dry and very salty. He asked me what I wanted to drink, I said flavored sparkling water. He said we don’t have that we have plain sparkling water. I’ve flown United many times and I know exactly what they have. 10 minutes later he asked me what flavor sparkling water I wanted. Did this with an attitude as if he was being bothered!

Starlink internet made the flight time shrink and I was able to work.

The plane was so old. I paid a ridiculous amount to fly business and there was no internet for six hours! This can't be happening in 2026 and especially in cross country flights where there are a high volume of business travelers.

The food could have been better and the entertainment could have better movies or streaming.

My flight from Boston to SFO was fine. Crew was friendly and helpful. Food was mediocre. Fright from SFO to MNL was not as good. My flight attendant was friendly but didn’t seem to have a lot of experience. She seemed overwhelmed. Also, this was the only red eye business class flight I’ve flown which only served dinner 2 hours after takeoff in a 13 hr flight. When I woke up 1 hr before landing, everyone was eating so I assumed bkft was being served. I pushed my button for help and no one came so I approached my flight attendant and she said they don’t serve bkft but she gave me choices for lunch or dinner. I routinely fly business class but I was disappointed with the lack of service and attention I was given on this flight. Also, most airlines will offer a snack or coffee before bkft is served but this was not offered during this flight. Overall, it was disappointing.

The food could be much better. Also very unfortunate that most of business class seats were empty but I could not upgrade.

Bag got checked but I thought one personal item was guaranteed.

The seats are very small, that is all the staff did a good job.

The flight was for my mom in wheelchair the staff in Newark wer not friendly took a long time to even get a wheelchair she almost missed her flight because they finally got a chair few minutes before boarding they had to rush her to the gate. They took her carryon and checked it as a bag told her don’t worry free of charge but they charge the credit card anyway. She also told me the seats are not comfortable at all as if they were broken she could feel the bars in the seat SFO staff was much better overall she had the worst experience

First class flight crew was barely available. They came through 3 times while we were on the plane for nearly 4 hours.
