Food was just okay, need to improve for other menu variations
Food was just okay, need to improve for other menu variations
The consistency with Singapore Airlines is fantastic. Crew are always brilliant and food delicious in business class
Wish the seat don’t have restrictions, can’t fully insert backpack all the way inside.
Service was top notch and the attention to passengers is great. Takeoff and landing was on schedule. Food selection is good
I have difficulties to book wheelchair for my parents returned flight
I was in a middle seat where I felt a bit too cramped otherwise the trip was good
The business class seats were very uncomfortable. When in lie flat position my legs were very restricted.
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.
Food from Surabaya was below average but from Singapore is much better
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.
