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.

The friendliness of the attendants, and the quality of the service.
Food was terrible , uncomfortable seats, WiFi did not work, will never fly Singapore again.
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
Wish the underseat compartment don’t have a restriction, can fit a personal item such as backpack fully like most Boeing
Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options
Everything was great keep up the good work 😁, can't ask for more.
Overall, very good. The food was better than expected with the exception of the pork and potatoes dinner at the end of the flight. My family all selected that dish and did not set it. I tried a bite also and it was honestly terrible. Also, it would be helpful to know when the snacks in the back of the plane are available.
The crew and their service was top notch, but the plane itself seemed to be on the older side and worn out. Also, the food could’ve been better. 9 out of 10.
It was just fine. The sirlines did live up fully to my expectation.
I was traveling alone with an infant, so the crew was incredibly helpful. Both the international and subsequent domestic flights were impeccable.
The ticket was last minute buy so no concerns about the pricing this time, but the crew in general could have been more accommodating, helpful.
good flight. food is only so so. I actually did not eat the snack. it does not look too good on the passenger next to me.
Super surprised with the entire experience. Business class is incredible. Flight attendants around the world could learn customer service from these people. Simply fabulous experience all the way around.
Excellent! I had read some negative reviews but I found out that it was not all was not true! The staff was courteous and helpful. The flight take off and landing was nice & easy. The food was good! I asked for a second and I got it easily and without an attitude! All was wonderful!
I think it’s time that somebody set a standard for the temperature in the cabins. I would rather it be colder than anybody that wants to have a blanket have a blanket to keep it so warm at times is unbearable and quite uncomfortable. That’s the only thing I would add.
The flight was cancelled without any reason. But the next flight to Shanghai has to be cancelled to pay penalty.
Again, I was presented with birthday pastries two times as a celebrated my birthday on both legs of my trip. I will keep flying to China using China Eastern airlines. As they made this trip a special one thank you.
It was my birthday while I was on the flight on China eastern airlines. They celebrated my day by giving me a personalized birthday card and also a very delicious pastry. I was surprised and thankful by the China Eastern crew! The whole staff was kind and professional? My second flight into China and the most memorable! Thank you-
