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.

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.

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

So happy I flew with Singapore Airlines. The customer service is top notch. I am terrified of flying and the staff made me feel so at ease. Will only fly Singapore internationally moving forward.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

Everything was great keep up the good work 😁, can't ask for more.

Check in was easy through self-check-in kiosks just like domestic flights. Staff onboard were fantastic. Some "book the cook" good options weren't great, others really good. Entertainment options a bit limited to what I've experienced on Qantas. Overall a good flight though, especially for the price.

The staff on Singapore Airlines was incredible. I would like to commend LS Reuben from my SQ37 flight on November 19th, 2024, from LAX to Singapore, for his outstanding service and care. During the flight, one of my earbuds—brand new and valued at nearly $300—fell out and became lodged in the box controlling the in-flight entertainment system. I was understandably upset, but Reuben went above and beyond to assist me in this tough situation. Reuben demonstrated exceptional determination and empathy. Instead of suggesting we wait for an engineer, he immediately took action, spending almost 30 minutes searching for the earbud. He even got down on the floor to ensure it was recovered. His genuine concern and persistence made all the difference and turned a frustrating situation into one where I felt truly valued as a passenger. Reuben is a shining example of the remarkable service that sets Singapore Airlines apart. His dedication and willingness to go the extra mile left a lasting impression, and I want to sincerely thank him for his kindness and professionalism.

The food options and quality could use some more excitement and variety.

I very much liked and appreciated the service on board. The seating arrangement in Business feels uncomfortable. It's not made for tall people, in any case.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

The best ever, friendly and attentive cabin crew, amazing captains who utilised their expertise for less turbulence, just overall amazing

Overall I was quite pleased with the experience; the cleanliness; the polite and attentiveness of the cabin crew; and the delicious food options.

I would never have been able to make the transfer in time without asking for a wheelchair

Good food, real silverware, polite staff, smooth landing, charging plugs, good entertainment options.

Loved that I had an exit row seat, and there was no one else in the row! And again, I don' use on-line entertainment at all (I read or sleep) but I very much appreciate that I didn't hear anyone else's entertainment!

The entire crew was amazing. They went out of their way to make us enjoy a great travel experience.

Loved everything! This flight had premium economy and I didn't see an option to upgraded to premium economy OR buy premium economy tickets. How come?

We had to deboard using stairs. Why didnt you have the aero-bridge?

Some Crew were distinguishably fake in their interactions with passengers.

We was missed the flight They doesn’t lest us fly next flight without payment They charge me 606 hundred dollars What is very unacceptable,our first fight ticket was almost 2000 dollars, again paid 700 it’s hurt … airlines need to do something please

All the crew members were too slow and rude. Most of the times the registers were empty, while hundreds of customers were waiting in line, and it was impossible to get a supervisor. Despite being in line on time, I missed my freight, plus a some customers who were ahead and behind me.

Seats very small and unable to pre purchase internet or seat upgrades

I recently travelled with Qatar Airways from Doha to Dulles in the QSuite, and the experience was nothing short of exceptional. The QSuite truly feels like a First-Class experience, with its luxurious design, privacy, and comfort. The cabin crew, especially the lady in charge of the cabin, was remarkable—professional, attentive, and genuinely kind. The food was excellent, and the comfort of the seat was absolutely first-class, making the journey smooth and enjoyable. While the in-flight experience was outstanding, I have a few points of feedback. Firstly, the content available in the in-flight entertainment system could be expanded and upgraded to include a more diverse and updated collection. This would elevate the entertainment experience to match the premium standards of the QSuite. Secondly, regarding the Wi-Fi service: while QSuite passengers receive one hour of complimentary Wi-Fi, any additional usage requires a fee of USD 10. Considering the premium pricing of QSuite, it would be more fitting to include unlimited Wi-Fi as part of the experience, further enhancing the luxury offered to passengers. Lastly, I must highlight an issue with luggage handling. Unfortunately, my luggage did not make it through the transit, which was disappointing. While the ground crew assured me that it would be delivered to my home on the same day as it was arriving on the next flight, this promise was not fulfilled, and the delay added unnecessary inconvenience to an otherwise excellent experience. Overall, the QSuite experience was exceptional, but addressing these areas would further solidify Qatar Airways’ position as a leader in luxury air travel.

Seating is terrible, having seats so crammed is unacceptable for a 15-hour journey. I cannot stress enough how uncomfortable it is to sit in such an aircraft. Leg space is roomier in a domestic aircraft. I have not experienced this kind of crammy seating in domestic flights either in the US or other international airlines overseas.

Do not overbook flights and kick out confirmed ticketed passengers :-(

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

Do I need to repeat my complaints about my lost carry on bag?

Noice cancelling headphones would be better since it’s a crowded plane And kids behaviors are unavoidable

More facilities to transport to the gates......felt too much walking distance

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.
