Over the wing seat at emergency exit only downside people using lavatory have no respect and wait in the space

Flight delayed any hour and couple of big gate changes

The pilot came out and chatted with the passengers. He explained why there was a slight delay. The crew was excellent. Very helpful. I had to buy meals for my whole family and they were in different seats, so the crew had to deal with that. They were very pleasant and accommodating and did a great job!

We were unable to land in Liberia. It was not the airline’s fault, but we had to be diverted to SJO.

We had things stolen from our luggage, we also were refused an upgrade on a flight that was not full.

When we left, it wasn't Great . People were drinking heavily, very disrespectful Extremely loud, the entire trip. I think the crew members, should have get their attention. Coming back was great.

I sat in the club. The seeds were fantastic. The meal was great and Entertainment was good. The crew was fantastic. I recommend it to everybody.

The food was small portions and not fresh. I was seated at the back of the plane so by the time the cart approached me most of the food options were sold out. The cabin crew was fantastic however.

Great flight and crew. Food isn't free and neither are headphones...

We were in economy class but paid for option Plus which offer you an extra snack after take off, free earplugs & blanket. The crew were very attentive. The comfort however wasn’t great, hard to be comfortable in such restraint place. Wasn’t able to sleep through out the 7hrs flight and was exhausted upon arrival.

Three of four legs of our trip to and from Japan involved delayed flights. Hours and hours of delay. Food poor quality and inedible particularly on the Japan to Toronto segment. Two planes on the Japan to Washington return trip required replacement aircraft to be flown in from somewhere. Boarding in the dark on the field, one passenger fell and was injured. Overall bad experience.

2.5 hour delay sitting in the plane on the tarmac, you tell me how the experience was

This was my first time flying Air Canada. My first flight was delayed and then cancelled due to maintenance issues. They kept us informed and put me up in a nice hotel along with 2 food vouchers for my flight the next day. I understand things happen and they took care of the problem very well.I also like the fact that they don't charge for your first checked bag. The food was also hot, fresh and good.

There is not enough room for people over 6 feet in the seats for a flight that long. Crew only came by when it was meal/snake time, in the 11 plus hour flight we did not see anyone walk around, on our flight to Japan we did not know where the call button was to ask for water, on the flight back we finally pushed enough buttons to find the call button

I hope these comments will find their way to AC customer experience team. Me and my spouse 50 years of aged coming back from 7 days perfect vacation... While boarding in FLL flight AC1621, one of the boarding agents (tall aged african american) man literelly yeld at my wife during the picture talking process. MAM ! STEP !! BACK !!! We are not illegal immegrants beying deported, nor are we in the millitary. We are customers returning home. This was unacceptable. While boarding in YYZ flight AC1154, one of the boarding agents (tall aged caucasian) man criticied with several complesant remarks my passport condition saying that I could not travel intl with it due to stain, decoloration, and BLOOD. My passport does not have blood on it! Yes it might be in less than perfect condition, but their are ways to talk to customer that does not imply not allow a boarding agent to be angry fathery like, or a custom agent looking at a suspicious individual. Both experience were less than acceptable for might I remind you a paying CUSTOMER returning home.

Lynda was rude and unhelpful. We asked for tea wiht a slice of lemon. She served us Coffee instead. When we spoke to her she made it seem as if we were lying. I asked if she would like to taste it and see - her reply was I don’t need to be rude. After this incident we were treated with subpar service for all beverages and food items after. We’re were purposely left out when they did garbage collection.

They lost my checked in luggage, why do I pay for my cargo not arriving at the same destination as me?

This flight didn't happen for me because of overbooking.

Terrible experience, flight was delayed both ways. Limited compensation for the 5+ hour delay. Will not be flying Air Canada Rouge, and don’t recommend you do either.

The boarding was relatively quick, the crew welcoming and flight uneventful. The omission of meals on all airlines is unacceptable especially when the flight is during a mealtime such as this one, (lunchtime), is unacceptable.
