Don't take the 6am flight. Airport security and customs only open at 430am. So if you show up the recommended 3 hours before, you're waiting in line for nothing

The check-in staff, boarding staff, and flight crew were all very friendly. Really miss the Porter lounge in Ottawa.

The check-in staff, boarding staff, and flight crew were all very friendly. Really miss the Porter lounge in Ottawa.

Thanks for giving a beer to everyone in the seat infront of me and then telling me that I can’t have one because they are going to land. I guess I need to pay for a seat and then pick one in the very front of the plane

The flight was delayed by more than one hour. The terminal was consequently overcrowded and hot. We lost our car reservation and hit rush hour traffic in Boston, which added two hours stuck in traffic to our trip.

Awesome, the whole way through. Thank you, this is the new Canadian Airline benchmark.

We were given a complimentary seat upgrade which was so unexpected but so lovely!

Porter was excellent. Boarding was a breeze. The seats were a little uncomfortably but the overall trip was excellent.

Only packaged snacks were served. It was a flight at lunchtime and a hot meal would have been a great.

Reserve check-in was very slow compared to regular check-in. Internet was slow

Lavatories broke with an hour to go. At least we were on time.

Chaotic boarding, but mostly my issues are with Toronto airport

HORRIBLE WITH THEIR WEBSITE!!! WORST WEBSITE IN THE WHOLE AIRLINE INDUSTRY

Did not even get on board. Was told I needed an esta agreement. Was not aware of this when I booked the fare and not told about them

Cramped seats. Audio jack for the in -flight entertainment was broken.

Flight was great albeit the long line before the int’l immigration given the timing of the year.

They canceled our flight and left us stranded to figure it out

We appreciated the friendly, efficient, and professional flight attendants. A wider selection of hot foods would be nice.

There was no room in overhead bin to place our luggage despite we had tree seats. It means a lot of people had more than 1 carry on bags. When I asked a crew member to help she said that it was not her responsibility.

Did not have enough time from Venice seaport at Ravenna to get to Venice airport in order to make the scheduled flights. Need to have at least 3+ hours from ship docking to airport.

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

Very old planes. Seats were not comfortable. Air was not on during the flight leading to incredibly stuffy conditions.

It was so bad experience they wanted just charged passengers for any reason.

Delta was great. West Jet was not. I booked my flight in Sept (well over two months ago), but was told there were 2 reservations and NO tickets for me, my husband and 16mo daughter. We were unable to go ahold of West Jet over the phone and the kiosk was unhelpful so we had to buy completely new tickets in order to get home that day. I’ve called West Jet twice since and sat on the phone for over an hour without speaking to any representatives.

The seats were some of the most uncomfortable I've ever been on. Other similar-sized jets with the same seating arangement have been far more comfortable. This interfered with sleeping, so it was a big issue. Moreover, the lack of a digital boarding pass forced an extra trip to print one, and the overall digital experience was poor. WestJet's website could not figure out one of my flights existed.

flight was delayed and stewards were preoccupied and not helping passengers. The pilot was very communicative which was great. The window was dirty as were the back of the front seats with chewed gum and slime on it. I hope this helps.

Traveling on two legs the food was identical and not very good

Agent checking me in was great. Plane was nice. Problem was with the handling of my fragile check in. They damaged my steel drum, waiting to hear back from them to see if they will take any responsibility. Think twice about travelling with something fragile, they don't seem to treat it any different than normal luggage

I had a problem checking in as I didn’t have the correct code. I had to phone BudgetAir.com. They charged me an additional 174US for some tax or something in order to provide me with my booking number. I will never use a third party seller again. Absolutely criminal activity. But I did get to where I wanted to go

Still sitting in a hotel when I'm due for work

Other than being delayed 5.5 hours and having to get a hotel because I missed my connecting flight, it was an okay flight. No in-flight Wi-Fi or entertainment.

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

3hour delay In the last 3 months i had 3 flights and 2 of these had a more than 2:40 hrs delayed

My initial flight to ORD was extended without reason. We circled the airport a few time and then drove on the ground for at least 20 minutes. These kinds of delays are annoying but somewhat expected… it would be nice if the crew would make an announcement to give updates on how long we could expect to be delayed.

Fantastic. I am low vision and was impressed with how helpful and accommodating the service tam was. It was super appreciated! I was pleasantly surprised about how delicious the food was. Like, “I wish I had more even though I’m no longer hungry” delicious. 100% enjoyable trip.

The flight was uneventful. What was a problem was I was delayed getting home one entire day because the flight from Sacramento was delayed. That made getting to my connecting flight impossible. I had to stay another night at the hotel and incur that expense as a result.

Flights were on time both ways, such a big plus! Staff was very accommodating and friendly. Question the choice of snacks that, which on both flights was dairy based. Appreciated using bottled water.

The TSA people or whatever you call them were a bit rude- I asked why I had to take my shoes off bc I'm 75 and in the USA, I don't have to. The man didn't need to snap at me. It wasn't even busy! The plane was ok, a bit small for such a long flight, but I'm very familiar with the 737 used ( I fly it often between SFO and SAN) service was ok-nothing special. If I drank alcohol I guess I would be happy with free choices. the plane was HOT and even the FA commented on it. They tried to get it cooler, but it never happened.

I have flown on many airlines all over the world, and this plane flight was the most uncomfortable I have ever experienced.

Flight from Minneapolis to Montreal was easy, breezy. Small plane, so not much overhead space. The seats felt slightly smaller than normal, but not uncomfortable for my body type. No screens in the seats for watching movies or shows, but I don't mind, I'm more of a reader.

Excellent overall experience. Seats were comfortable and ample leg room.

Con: Travelers shouldn't have to pay a fee for first checked bag, in any fare class. Pro: Plane was new and comfortable, even for the seats that didn't cost extra.

Wheelchair help is not reliable & chaotic. No food and minimal liquids for a flight at 6;25.

I wasnt able to choose my seat during booking my flight _months_ in advance and then when I checked in for my flight, I _still_ couldnt choose my seat. I was finally able to get a seat when I got to the gate, and they stuck me in a middle seat next to a jerk. This was my return flight, and on my departing flight I was able to choose my seat, so I dont understand what the issue was but it was very annoying and a miserable ~6.5 hours on the return flight.

Gate changed twice, boarding late. However, there was more than usual leg room. Crew was fine. No entertainment due to computer problem.

I don’t think the on-board testing worked on any of the 4 Air Canada flights for this trip. And in this particular flight, the entertainment and WiFi was out for a portion of the journey.

Ok, a very small soda in a small glass was all that was served. Pitiful. Comfort seat was not, no legroom at all would not recommend comfort class, not worth the extra.
