Original flight was delayed, then cancelled and the gate staff did not expedite rebooking. Also, no instructions were given that a ticket number was needed before being called to facilitate rebooking. This could have been much more organized.

Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

Five hour delays every hour, I wish it were all at once

Flight delayed four separate times. I’m now one hour hours late to landing.

worst flight ever from Delta, it got delayed and kept on delaying..

Should never have had to go to Detroit from Orlando back to Tennessee!

Got rerouted from a straight flight from Orlando to Atlanta to Knoxville to a flight from Orlando to Detroit to Knoxville! Seriously!! Flight delay out of Detroit! Long day for what should have been a pretty easy travel day!

Two delays on two separate planes with parts they could not easily find and replace.

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

Packed flight, which makes it tough on crew and boarding staff (and the customers of course). But this was great boarding, clear instructions, etc. Traveling on the weekends are always fraught with danger as you have families and less frequent flyers thus more confusion. But this flight went as planned.

Boarded early, left early, arrived 40 mins early! A win win for me!

I felt scammed. The priced advertised was different than what I paid. I paid the whole some online. I then got a call 20 minutes later saying I need to paid 70 more person. She said the price online is not the guaranteed price.

We had a delay, but thankfully I made it to my connection. Overall it went smooth

Left an hour and a half after the listed time. Up side was it had TV screens on the seat.

It's a long flight and I would have liked better snacks between lunch and the arrival meal. It's fine to have fruit and nuts but I really don't like ramen because it's salty junk soup. I'd suggest sandwiches. They're not expensive nor are they hard to store for a long flight. The FA's had a couple of big services and they were super busy preparing, executing and then cleaning up. Then they disappeared.

Great flight. Got to watch a movie. Smooth flight and early arrival at ORD.

I've been flying American mostly, and it's been very frustrating. This united flight makes me realize maybe the issue isn't flying, but the airline. United was a significantly better experience. The plane was more comfortable, with a normal amount of leg room (vs the ridiculous reductions AA has made), more comfortable seats, screens to watch movies. It was a much better experience!

We had excellent customer service despite the chaos at George Bush airport in Houston!

It isvvery small flight. No leg room . No space to put my personal item at feet.

This airline would not refund my money and I had a physician note that I could not fly. They are crooks

I like that we landed safely and that my dog was safe underneath as well. Outside of that, we were 45 mins late for a direct flight that is 1.5 hours long. And 2 of my 3 bags did not make the flight. Only my dog was onboard.

Decent entertainment although my wife was not offered any ear buds so couldn’t enjoy. Real issue was the appalling food. Presentation was unacceptable with cheap hard to open packaged bread, plastic cheese again in hard to open shrink wrap, main course in small cardboard box again hard to open, wooden utensils which lack substance making the whole experience poor. Surprised I didn’t cover myself or neighbour as the food moved all over the place. Breakfast calzone was dry and unappealing with the staff basically throwing them around. Very disappointed

The flight didn’t happen because they apparently lost my check in and wouldn’t let me board.

I wasn’t checked in for the third leg of my flight, my bag was checked through to Dublin but when I went to the gate in Toronto they said I wasn’t on the flight and had given my seat away. I had to wait 24 hours for another flight and instead on the one I had booked it was now 2 flights.

Flight was delayed by 3/4 of an hour. Overall flight was good.

No pre boarding kiosk to check in, baggage claim detected luggage didn’t leave the airport, poorly managed recovery of lost luggage, and blame lost tag from conveyor to TSA/security, very poor from TSA/security check to delivery, crucial if compensation will go thru and will likely wait for months unlike United,

Waited at airport from 10 am till 4 pm and no flight due to fog. Ugh.

Plane was one hour late. Hardly any space for our carry-ons. Stressful to catch connections.

Plane seating was uncomfortable, very tight fitting for someone my height, did not recline and overall un enjoyable

Flight was overbooked and seats assigned to multiple passengers. Delay 1 hour to sort out.

Staff were very friendly. Plane left on time and arrived on time.

The TV screen at my seat was not functioning for the entire duration of the flight. I informed a flight attendant about the issue, and I was told that I would receive a voucher as compensation. However, I never received this voucher afterward. I therefore kindly request to still receive the voucher that was promised to me.

Our original flight was cancelled due to mechanical reasons. This cancellation caused us to miss our connection and we were not able to get another flight for 3 days and then needed to make an extra connection to get there. Air Canada did not rebook our flight for us, it took several hours of talking with staff in the airport and making phone calls to get the flights rebooked. We never received a voucher for our hotel and meals while we were waiting for our next flight and it was only after talking to several staff that we were provided some general information about how we could be reimbursed. We tried entering our ticket information in the website provided, but it did not recognize our flight information. When we asked someone on the phone about this they said we'd need to contact the customer relations department, but that it's not possible to reach them on the phone. I don't understand what company would have a customer relations department that you can't talk to. We spent about $1,000 for hotels and meals for our family while waiting for a flight home and I'm not confident we will ever get reimbursed for this. I understand that mechanical issues can happen to any airline, but this is the 4th time that this has happened to my wife and I on Air Canada and we have only flown Air Canada about 8 times, so this is not a good track record. Also, when we did finally get a flight home (which was also delayed due to mechanical problems), we were told we couldn't bring a standard carry on even though the information on our ticket clearly indicated that we could bring a carry on bag. The staff at the gate were not understanding about this situation.

We were happy with the service and cost of checking a bag

Very nice staff members are very nice and friendly helpful

The internet connection was perfect, and the updated entertainment systems that allow me to connect my Bluetooth earbuds was excellent

It was good to receive a card for my birthday

It would have been better if it wasn’t cancelled

Flying in the Dreamliner is always comfortable. Though the food options for Air Canada aren't great.
