I find it was a bit hot before take off. If there is a way to improve the airflow it would be great

I find it was a bit hot before take off. If there is a way to improve the airflow it would be great

Excellent service. I pre-ordered gluten intolerant meal and they handle it with care. They served me my meal before other people's to avoid crossed contamination. Thank you 🙏

No frills airline with minimal leg room and no entertainment

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

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

Better entertainment & food options more may be adding chicken option or on vegetarian side good quality pasta

My seat was not comfortable. Flight was smooth. Regretfully we had two delays before takeoff

Amazing service, with enthusiastic crew members, and some breathtaking views of Vancouver. No IFE though, as it is only a 1 hour flight on a regional Turboprop jet.

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
