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.

They are very proactive and made our boarding easy and always notified us about any changes well in advance.

My seat was covered in vomit and I will be reaching out to Air Canada

It's kindof ridiculous that your system is even asking me about this since my flight was canceled and I wasn't rescheduled.

3 hr delay at the gate while they were doing maintenance. Next time, do not board passengers while maintenance is being performed

Digital check in is very poor with air canada compaired to other airlines

Baggage delayed we had to catch our cruise without any clothes 😒

Air Canada Rouge is great. Toronto Airport is the usual nightmare

Good but need to be better with the flight times.

The staff could not have been any friendlier. Lots of usb ports on our aircraft.

The staff was great and made the long trip easy peasy!
