Pros: "Return flight from Singapore to DC via Tokyo was more pleasant. The stewardesses were more service oriented."
Pros: "The 787-900 used is a great aircraft from passenger comfort and the overhead bins can take all your carryon bags."
Cons: "Our flight used a remote gate - so we had take a bus to the plane... therefore had to drag our carryon up and into the bus... then up the staircase into the aircraft.. it also made us :30 late departing"

Boarding was fast and efficient. Not a cramped plane and good comfort. Food was great and attendants were very nice.

Crew was professional. Never enough leg room for 12 hour overnight flight.

Fast boarding. Cabin temperature was a bit warm, but I guess this is the standard in ANA. The Room seats are spacious, but not long enough for me.

ANA crews are superb, very responsive and caring. Boarding was smooth and so as the landing. Great flights we had with ANA.

ANA was wonderful just needed to upgrade the food and the entertainment.

Crew were efficient and friendly. But my seat was very uncomfortable . Was seated at last row window seat 27. Too cramp

The crew was so accommodating. If I asked for extra snack they gave it to me. In economy the seats were wide and plenty of legroom. The backrest should have reclined a little more. Instead it barely moved. The footrest was helpful. Overall, my experience was good and I would recommend ANA as an alternative to other oversees low-cost airlines.

Older 777 - showing lots of wear - Premium econo seats that are difficult to recline and worn springs to they don't return to takeoff position without standing and pulling them forward

I booked a ANA flight, this was just a regular United flight — as always very bad, dirty, rude service, quite frankly really embarrassing to be flying with this after spending time in Japan.

Staff and crew are wonderful, professional and courteous. Meal is delicious and snacks can be improved. Entertainment needs improvement, pls update selections of movies. I appreciate that our flight was on time

The airline was very clean, and the crew very kind and thoughtful.

Service is excellent - crew all so respectful and friendly. Airline comfortable - lots of legroom even in economy. Food was great even came with ice cream!

Just a little puddle jumper from Los Angeles to Vegas. Not much can be said, I had to go ask for some water.

WiFi inflight was not working. Then they told everyone they had no beef for the steak option. So that left just sea food and snacks. So all I ate for the 11 hour flight, was an ice cream sundae. Gave out Casper mattress pads, which are always so nice.

Management of serious allergens despite advance notice. Did not know ingredients contained in their own food. Went as far as to have parents try to ‘take a look at the food’ to ‘see if it was Ok’ since they did not know ingredients. Will inevitably have a passenger with a severe incident if they do not train better.

Great service. Premium coach seat was uncomfortable. Food was non-descript.

Will definitely try to book with them again next time. FAs are very helpful and nice, bathroom always clean & flight was comfortable.

Very pleasant, look forward to flying with JAL again if the price is right.

All of the JAL flights in this itinerary were great. However the last leg of my flight from LAX to SFO was through Japan Air’s partner, AA which wqsn’t up to par. We were informed only minutes before boarding time of a delay despite the airlines knowing about the delay far earlier (the aircraft we would be taking arriving arrived and disembarked close to our boarding time, for all to see but AA still kept the original boarding time posted until last minute). Furthermore, once we boarded the taxi/wait time was also extended, with the pilot blaming “construction at SFO” for the delay, rather than taking accountability for the the plane’s late arrival coming into LAX. We took off approximately an hour later than scheduled. It’s for these reasons I adamantly avoid American Airlines when possible. Again, JAL was stellar.

Great service but food taste and options have gone down a few notches.

I had to change a flight date and it cost me $800.00 dollars. In the past, if there was room on the flight(which there was), Singapore Airlines simply re-booked me. This might have occurred because the office in Bali where I could interface with a human face to face is now closed since COVID. I naively figured the ability to change my flight into my decision to go with Singapore Airlines as it does cost a bit more. I will still fly on them as they are superior to the other carriers by a fairly large margin, especially for my needs.

I was traveling with my 3 minor children, one leg I was seated two aisles behind them. On the longest leg I would have preferred sitting across the aisle from them, not behind. My youngest is 4yos. I understand airplane seating configurations are not the airlines problem but seating the one adult with a reservation apart from the minors was very difficult.

Crews are not allowed to perform any service whenever the captain deems there’s a chance of turbulence. Even if it is perfectly smooth air.

They ran out of food for breakfast They did not offer tea or coffee The staff appeared very inexperienced The cabin was very cold, even with a blanket

Too many luggages for 1 passenger (4 bags) will make all the overhead luggage bins a challenge to fit them all. Some have oversized hand carry as in like back packer size bags shouldn’t be allowed as handcarry.

plus: service and personal assistance minus: online check-in did not work

My experience with Scoot is very good. Will have no issue flying with Scoot again.

My overall experience with Singapore Airlines is great. Will definitely fly Singapore airline again.

Good flight. Fiod was ready a bit late hence a hurry to finish before landing. Excellent crew and service

Great to have actual hot tastey meal on a flight. Well done

There were issues with the first segment but what really bothered me overall is that you rebooked me and put me in a seat away from my wife and then put her in another booking or boarding group. I don't like having to monitor every little thing you guys do in order to get what I paid for in the first place.

Calgary desperately needs a star alliance lounge in the transborder area for United.

Delays!!! Serious delays. I was told by a member of staff in LGA that I would miss my DEN to LAX flight connection, so I was put on a later flight. Due to delays I would have been able to have made my original flight, where I was sat in business class - seat 1A: I was put on my original flight but bumped from business - 1A to economy 33C. I want a refund for paying business class but only flying economy

Miserable. Active military on orders turned away from Lounge because not in uniform. This is completely contrary to United’s online lounge access policy. Sad that employees aren’t trained better. This is not the United Airlines my parents used to regularly fly with.

Too many canceled flights and kept my wife and I separated on alternate flights. We did not fly out of Denver. We paid a lot of money for the seats we wanted and now that money is gone and we did not sit together. That being said, the many agents were very friendly and did everything possible to help us.

3.5 hour delay known 12-16 hours before departure $15 meal vouchers which did not even cover cost of sandwich. Unable to reach agent for 1.5 hours, only then to be informed any rerouting to my destination would cost an additional $1000. Finally got rebooked on a 7.5 layover in Denver only to find out my original connecting flight was also delayed so I stood by and got on my original connection arriving only 3 hours late instead of 5 hours late. Overall journey was unnecessarily stressful and lenngthy!

When I got our tickets, my husband and I were easily able to get seats together (including a window seat). When we checked in at the airport all the seats were reset and we had to pick new ones, so we couldn’t sit together because there were only middle seats! Ugh that’s the worst. We were back so far we had to check our carry ons which was annoying because I bring an expensive camera that I don’t/cant check so I had to reorganize my items. Once we were seated on the plane we had to wait an hour to take off and they said there was some weather/air traffic in Denver but it was unclear. The lady I sat next to complained that our seats didn’t go back and we both got free complimentary snack boxes which were quite good. I wasn’t going to say anything about the seats, they were the typical uncomfortable kind. It would have been fine if the 2 hr flight hadn’t turned into 3 hrs. Not the best flight but also not the worst.

We love United Premium Plus! So comfortable without the cost of Polaris Club. The crew was so attentive and friendly!!

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Not worth the price of premium class ticket paid, felt more like steerage.
