I was in Comfort and we didn’t get any drinks, chips or anything! First Class got full service on the flight and Comfort got nothing. Seat was horrible and uncomfortable

I was in Comfort and we didn’t get any drinks, chips or anything! First Class got full service on the flight and Comfort got nothing. Seat was horrible and uncomfortable

Short trip, no food and therefore no expectation for much interaction with staff who were pleasant and professional. My critique is on comfort of the seats. Exit rows and comfort seats do not provide enough personal space for 3 side-by-side seats, especially when in the middle row. Some passengers are not considerate of the middle seat and there should be signs that state something to the effect of: "please consider giving middle seats use of the armrests."

The tray table was broken and the food was terrible.

THEY FAILED ME AND I NEVER GOT ON THE FLIGHT BECAUSE IT WAS SO DELAYED! I ENDED UP HAVING TO PAY OUT OF POCKET FOR A HOTEL AND STAY IN NASHVILLE TO CATCH A FLIGHT FOR THE FOLLOWING DAY. DELTA IS POOR CUSTOMER SERVICE>

It would’ve been nice for all that money to have a more substantial snack for free. I remember once upon a time getting a very nice turkey sandwich with Swiss cheese on whole wheat bread for no charge along with a drink. I guess those days are gone. it’s a little insulting being given a cookie or a bag of baked chips Going forward I’ll just bring my own.

The aircraft interior is old and tired on this aircraft. The entertainment system never worked despite the crews attempt to reset the system.

Lower number on this flight so spaced out passengers. Able to enjoy more room to relax during flight. It was lovely.

Canceled last minute. Also canceled another flight that my brother was supposed to be on. Delta is horrible now. Never flying them again.

Inconsiderate staff, plane was very hot, poor decision-making from the crew.

More filling food and more entertainment options would be cool.

One small cup of warm soda for a 4 hour flight. Disinterested, unfriendly flight attendants

Flight was canceled due to mechanical issues. After a considerable wait in the queue, Air Canada customer service was very helpful to get us on another flight. I am disappointed to report our rescheduled flight is for three days from now. Three days of extra expenses and inconvenience is unacceptable.

extremely cramped seating... absolutely no leg room and when person in front of me reclined... I was pinned in my seat... absolutely ridiculous

Take off and landing and also the crew were excellent, just we could not received one of our suitcases at Ottawa at the same time we got there, but the associate at Ottawa airport were very nice and helpful so we could receive it on 16th of September.

They served us 1.5 pieces of chicken nuggets with coleslaw..felt like a toddlers meal in business class. Why bother?

It's hard to separate the frustration and stress of delays, which may or may not have been due to AC, in my experience. My Nashville/Toronto flight was delayed due to baggage loading, to the point I missed my connection to Ottawa. I was automatically booked on another flight but it was the latest one of the day getting me into Ottawa the next day. Linda, Customer Service desk in Toronto, got me on an earlier flight AND made the calls to get my baggage on the same flight. (High marks for Linda and her efforts! ) I ended up in Ottawa about 2 hours late, but my carryon bag which I volunteered to gate check to make it easier for AC, got the retractable handle tore off. Sorry, but it was a mixed bag experience for me. Linda was definitely the highlight of the trip.

We were over 3 hours late leaving Nashville. I am a new traveller, so it was very stressful not knowing if I'd miss by connecting flight to Victoria.

In Nashville Airport air Canada employees very unprofessional and that leads to a last one of our luggage.Will NOT recommend to fly with air Canada from Nashville. Jerry

Both my planes were delayed. I missed my flight in Toronto and got into Montreal at 4:00 instead of 1:15.

Crew were great. No snacks available. No entertainment. Seats a bit crammed.

Crew was very friendly. Need lay flat beds! More snacks

Good. Rxception is the Entertainment - movies and TV shows all out of date…

I liked the crew but not the uncomfortable seats and lack of movie and tv selection.

They cancelled our connecting flight resulting in another layover reaching our final destination 8 hours later than scheduled.

On-time arrivals and departures. Crew helpful and friendly. Yet everything costs extra: seat selection, food, even airphones!

Second time with Saga Premium, everything was fab, but the entertainment centre on both my flights didn't work, plus the seat on the NY to Rek flight (Airbus) was so solid and so uncomfortable. The 737Max flight's seat was much, much better.

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.

Delays at check-in, seemed like they were short ground staff at the time and some passengers needed extra processing.

Food - Non-Existent. You pay for everything. It is strictly Pay-to-Play!

The crew was wonderful at check in, the gate and on board. Felt the luggage had more room than the passengers. The seats were smaller than most domestic U.S. airlines. I'm only 5'2" and I had little legroom. There were only 2 bathrooms in coach. Needed more. The flight was very smooth but not the most comfortable.
