Airline reviews

Our itinerary included a 1 hour and 30 minute layover, which should have been sufficient under normal circumstances. However, our original flight was delayed. Before we even deplaned, we were instructed to collect our checked bags from baggage claim, clear immigration and customs, and then recheck our bags for the connecting flight. The airline knew—or should have known—that this was impossible. Checked baggage acceptance closes one hour before departure, meaning there was no realistic way for passengers from the delayed flight to recheck their bags in time. Despite this, the airline gave us misleading instructions instead of informing us that we would likely miss our connection. We completed immigration and customs in approximately 10 minutes, but our checked bags did not arrive at the carousel for more than 30 minutes. After collecting them, we had another 10-minute walk to the baggage drop area, only to find that no airline attendant was present. We then went to another airline counter, where an employee told us this had happened before and that there was nothing they could do because the baggage acceptance window had already closed. At that point, there were still 40 minutes remaining before our flight's departure, yet no one was willing to assist or offer a practical solution. When we asked to be rebooked, we were simply told to call the airline's 800 number ourselves. There was no accountability or customer support at the airport, leaving us stranded in a foreign country with no immediate assistance. After finally reaching an agent on the 800 number, we were rebooked on a flight for the following day. However, we were initially told that the airline would not provide any hotel accommodation and that we would have to arrange and pay for it ourselves. Only after making multiple calls and speaking with several different agents did one representative finally issue a hotel voucher. The entire experience was an exhausting and frustrating ordeal. What should have been a 20-hour journey ultimately became more than 30 hours due to the airline's poor planning, misleading instructions, lack of accountability, and inadequate customer service. The unnecessary delays, confusion, and absence of meaningful assistance caused significant physical exhaustion and severe mental stress. This experience fell far below the level of service passengers should reasonably expect.

Switching flights in Halifax was a nightmare. There was no agent waiting us when we disembarked to provide my mom with gate to gate assistance as we arranged. Our flight was delayed so our window to catch the other flight was very tight. The airport was poorly marked as to where to go. The plane was fairly crowded and space available was cramped.

Good flight. We were all boarded in good time for departure time but baggage loading had barely begun. So left late. No food just snacks and basic drinks for free (food also for purchase). No entertainment as again, unable to connect with wifi on WestJet despite being a rewards member.

I like the idea of a non-overnight flight to Europe.

The food was very good. I was nit expecting a meal on a red eye trip. I was pleasantly surprised! Plus we arrived a few minutes earlier than expected!

There was no food but a singular cookie for a flight that was over 5hours??? Yeah not fun I was starving and again super cramped plane and you guys need to get planes with screens too, WiFi is nice but common we need more

The agents at the Kelowna YLW airport were really grumpy. Same with oversized baggage person. Staff on the plane were great.

They lost my bag. Hopefully it will be here tomorrow.

Lost my luggage. Filed a report and there is no response. Received a phone call from another airline that said they had the bag and they did not know what to do with it

Terrible! Delayed three times, landed at some corner of airport, walked in bitter cold night, took a bus, bad experience

Got denied my flight was told on Google that Air Canada was supposed to book me a flight back home because I never was able to go to my destination. They did not help me whatsoever. I had to book a whole new flight for that reason I would write this is zero

Air Canada cancelled our flight and reschedule it 26 hours later that completely interrupted my family's long waited Japan trip, it wasn't due to natural reason such as weather but under the company's control. On the day we wasted 9 hours of our time from 6am to 3pm, including a few hours in the customer counter waiting for supervisor to handle our rescheduling. When we came to the counter for rebooking help there were at least 4 employees on the counter but we were told they were not trained to handle customer rebooking, we were also told the supervisor could come 10:30 to handle our rebooking, but she showed up more than one hour later, the end result was exactly the same so the few hours we spent waiting for her was completely wasted; We already prepaid hotel and all the tickets for the our stay in Tokyo so all of the cost for the first day is completed wasted; The $80 meal voucher issues was far less than our financial loss due to the financial cancellation, and it was not surprisingly invalid (as Your company screw up everything possible along the flight), the vouchers were supposed to last 72 hours, when we tried to used it at our lounge next day less than 24 hours from its issuing at a designated restaurant, the worker there couldn't scan the vouchers after multiple tries on all 4 vouchers issued, so we had to pay the food from our own money; For the two return flights they were also full of unfortunate events that caused bad experience and further delay and waste of our time, both flights departed late and the last leg had another significant delay of more than half an hour after touchdown, the gate was for some reason not available so we waited more than half an hour, when we got out of plane it was almost one hour later than the supposed arrival time; The gate you arranged is the farthest in Vancouver airport, also was the luggage pickup location in Seattle airport; We also called customer service for rescheduling help and after a long time wait (more than an hour) we got a call back but the CS representative was equally clueless and unhelpful. Other than a fatal crash, your company couldn't do anything right and provided the worst service possible among the tons of flights we have taken in our lives.

Boarding was challenging as we had to use the stairs from the tarmac. Stairs are okay but a roller bag makes it challenging.

My one complaint was that while we boarded using the standard enclosed gangway, when we arrived at SEATAC, the ground crew were slow to hook up the stairs. After reaching the tarmac we had to walk up a long ramp all outside in 35° weather. We just came from Bali and did not have warm weather clothes. This was in addition to having to collect our bags in Vancouver, take them through security again and then having to show our passports 4 more times all within the Air Canada section.

3 hours late departure with no explanation. $160 luggage fee (two passengers) for less than 1 hour in the air!

After i biked my flights, i was informed my flight was rescheduled for later time

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.

Flight was cancelled. Still stuck at airport. Going on 2 days straight, no sleep. Never fly Air Canada

My husbands flight last night Vancouver/Sydney was 90 minutes late in leaving. My flight tonight Vancouver/Seattle was also late in departing.

Air Canada had a lot of delays on our flight going back to Seattle. So much inconvenience for a long trip.
