No food at all so it was a bit of a culture shock for international travellers with connecting domestic flights.

The foods were lacking in both quality and quantity. I was starving.

My only complaint is that the flight attendant that I encountered was not receptive, unhappy to help me out prompted for help with my carry-on luggage to be put up into the over-head compartment. At time of booking, I’ve informed the customer service about my medical-surgical history necessitating assistance in carrying luggage(s)/baggage(s) especially lifting over head. I know crews’ policy of doing such. But, there should be exception(s) to that rule; a consideration for disabled people.. Especially noting given the passenger’s med/surg’s history. Hope, something will come out of this survey. Thank you for your kind understanding and cooperation regarding this issue. So I can still continue flying with any airlines in the near future.

American Airlines has horrible food. Also, since I booked a trip with JAL for all segments, I was surprised and disappointed I was on American Airlines from LAX to Haneda. I paid for JAL and received a much lower quality.

American Airlines Business Class does not meet the standard it should when compared with Japan Airlines, Qatar Airways, or Air France. The flight attendants often appear disengaged and fatigued, with forced smiles, noticeable attitude, and occasional rudeness. Food options are subpar, the overall ambiance feels cheap and outdated, and the cabin design reflects a past era rather than current premium expectations. Lastly, the aircraft itself felt old and uncomfortable. Overall, the experience is not competitive with what peer airlines are offering today.

This was serviced by American Airlines. Not as great as Japan Airlines. The LAX domestic airport is not a great airport. We needed to take a shuttle to go to the gate. Mind you, this is just a connection, but we had to go to security again, which is a hassle after a very long flight from Japan. It makes sense, for our checked baggage to be picked up and moved to the other carousel for our final destination, but for us doing the security all over again, pointless. We had our boarding passes already when we were still in Japan, yet we had to start from zero again when we arrived LAX. There should at least be a different line for connecting passengers without going out like it’s our final destination. Next time, I will try to book our flights from any foreign countries non stop to my destination.

I really love their services! From checking-in to deplaning, superb! Highly recommended!

The flights were on time and the cabin crew were very nice. The only downside was that the food was not good

I like the intention and service of the flight crew. Japanese values were observed and appreciated as a customer.

Our flight was delayed by one hour. Luckily, we were still able to make our connection. This flight is really an Alaska Airlines flight and not the same excellent service and comfort as Japan Airlines.

Crew is excellent Wifi needs to be improved in order to connect to the internet.

The flight arrived on time. 2×2 seating meant no one needed to sit in the middle. This was a connectibf flight from Singapore and required going to 3 counters in different levels to check a golf bag

Service was top notch and the attention to passengers is great. Takeoff and landing was on schedule. Food selection is good

Lounge a access was excellent as was the attentiveness and service from the crew as always. The food and drink supplied were of good quality. The entertainment system had a good selection and I liked the mapping system supplied. However the screen wild have been bigger and the operation a little smoother to navigate. The seats were barely comfortable, but adequate.

The staff on the plane were attentive and friendly. The frustration with the cabin crew was that we were served second to special diet people. And, we were in economy section. The boarding staff was mediocre. Got scolded for requesting to sit with spouse on 14 hours long flight home. Was told they cannot break up families for us. Didn’t understand how we were denied sitting together as we are husband and wife. After many words of exchange, we were accommodated. Cleaning crew did a horrible job! Bathrooms were unsanitary or dirty from beginning of flight! Didn’t expect sparkling as its economy, but did except decent.

Headwind delayed our flight which wasn’t the airlines fault

The usual excellent experience with Singapore Airlines. The airplane was on time and actually early to Haneda Airport. The onboarding experience was pleasant with no delays, perhaps owing to the fact that the flight was not full. Nevertheless, the air crew were their usual outstanding standards in serving the passengers.

Horrendous. We upgraded and they took the money but cancelled one of our tickets. The recline action didn’t work on the seats for the flight from Singapore to London, pre booked meals but they seemed to have disappeared as well.. Phone customer service was horrendous. Took 5 phone calls and no fix. Craig at the airport was the only one who seemed to be able to get the ticket back.

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.

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.

We booked with Qantas instead of Delta and we instead flew on American Airlines. American is not our favorite to go on. No leg room and the width of seats are a joke. Your are packed like sardines on American flights.

My experience was great overall. Tanya was particularly friendly and helpful the entire trip. I was very pleased with her customer service skills. The plane was an older aircraft but the entire way was comfortable with barely any turbulence at all. Qantas should speed up its fleet renovation. Totally recommend using this airline.

When I originally booked this flight, I was expecting to travel on Qantas. When the itinerary changed and the long-haul segment was operated by American Airlines, we were disappointed but remained open-minded. Unfortunately, the overall service experience fell far short of expectations. This was a long-haul international flight. Getting up periodically to use the restroom or stretch is inevitable, especially on flights of this duration. However, each time we stood up, we felt as though we were inconveniencing the crew. The tone and body language often suggested that we were in the way or disrupting something simply by moving about the cabin. As a result, I avoided getting up as often as I needed to and was physically very sore upon arrival. Meal service was similarly impersonal. The options were presented in single words “beef or veggie,” “pasta or beef” without any description of what was actually being served. There was little engagement or courtesy beyond that. Even simple expressions of gratitude were often not acknowledged. I am accustomed to no-frills travel and do not expect luxury. What was disappointing was not the absence of extras, but the absence of basic warmth and professionalism. On a long-haul international flight, small moments of courtesy and humanity make a significant difference. In this case, the experience felt transactional and dismissive rather than welcoming. I hope this feedback is taken constructively, as there is a meaningful difference between efficient service and indifferent service.

Qantas is always subpar beyond comfy chairs for a domestic flight

an hour late, then had to disembark on back stairs and take 4 flights up to get to main airport. No warning, and difficulty for those with canes and poor knees.

Flight arrived late with no one to help over 30 people rebook. I slept at the airport.

Business seats not as comfortable or private as most competitors (e.g. Qantas was outstanding), and movie selection was much more limited than Qantas or United has been recently

Hard to move and get out of my seat when the passenger in front is in recline position.

It was a good flight and no complaints. It just wasn't anything that was better than any other flight.

The crew were wonderful - if only the customers were as well behaved as the attendants!! Ha ha! If you could just talk to God and ask for less turbulence next time.... Juuuuust kidding....
