The flight was terrible based off the temperature in the plane and the air smelled so stale and gross. I have never wanted to hosed lore in my life after I got off. The food was disgusting and seemingly low quality. The staff was friendly. The bathrooms were so gross after a couple of hours. I will definitely never book with them again.

The food was disgusting and seemingly low quality. The staff was friendly. The bathrooms were so gross after a couple of hours. I will definitely never book with them again.

The crew was great. There was no entertainment and the internet wasn't working. We sat in the run way for a LONG time which is always so upsetting. The seats are very close together and the flights are completely full which makes for a tough flight. Flying is just an uncomfortable experience.

Very kind crew. Vegetarian food better than usual. Prompt take off. Entertainment worked well. Could always do with more room!

The dinner was bland and boring, but the economy seats were surprisingly comfortable. The flight was very packed.

Great crew and entertaining Captain. Seats were not what we had expected based on my booking but things worked out in the end. Of course, like all airlines these days not enough leg or elbow room.

The entertainment system was down; food by purchase only; several people did not receive their luggage. No one answers at the local office or online about the luggage.

This has been the worst experience I’ve ever had. Basically, I lost my round-trip tickets because one of my last names was missing, and you didn’t allow me to correct it. I had to purchase a full ticket again. Once I get home, I will start legal proceedings against you.

It’s ok just the boarding point is far too far

They are a sister company with Air Transat and the two companies do not work well together. If you have any issues the two companies will blame each other and you will miss your flights. The help line does not help

Flight delayed any hour and couple of big gate changes

Maybe glass of wine would be nice at no charge

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

Access to movies was rather confusing. Apart from that, I have no complaints.

As someone who never flies WestJet unless there is no other viable option I have to give this crew credit where credit is due. Extremely well done everyone.

Flight left on time. The crew was very friendly. I had to buy a proper meal. Small cookie and a drink just doesn’t cut it for a 4.5 hours flight.

Experience was good, the wifi hook up is somewhat tough

No dogs! Can we have no dogs in the cabin? Why was there a yappy little dog behind me? Lucky I had ear plugs. Sorry for others without

Arrival at Comox from, London,ON 6 hours later... No bueano

Flight delayed, missed my pick-up had to Uber, plus missed dinner and medication, so sad!

I booked through westjet. The first flight left late and cost us the connection to the second flight. The second flight after a 4 hour delay was again late because they were short an attendant. Then a door malfunctioned on the plane which led to yet another plane. So by the time we left Calgary we missed the BC ferry and had to pay a charge to get a later one. It ended up being a 24 hour day. That wrecked our first day and part of the second day in BC because we were so overtired.

Delayed on the way in 2 hours!!! And now on the way home delayed then cancelled!!!!!

Delay in luggage again for the second time of the trip. I would not advise using air Canada or at least I will never check in a luggage. Luggage issue overshadows the nice crew members unfortunately.

Air Canada was fine but air Canada rouge and air Canada express was terrible with luggage delays. First flight was cancelled so my luggage did not make it to my destination with me. The second flight returning not sure why but my luggage did not make it on my connecting flight. Overall terrible with handling luggage.

The baggage drop-off for Air Canada in Toronto for passengers flying international was terrible. One of the worst experiences I have ever had. The line was ridiculous; there was no one to help facilitate people avoid confusion, and the baggage system for the line I finally ended up in had to be re-booted right as I got to it.

Flight got canceled. Instead of the booking me for the next flight at night I was booked for the following day at a later time. I was able to fly out that night because I had to call and deal with a human!!!

My flight was delayed My connection was almost missed. My bag was lost My valuable items get damaged

Too many delays. Seats too small. A budget airline. Will never fly Air Canada again.

Horrible, we were on a little DeHaviland 400 that was really small and shaky. I am 5' 4" and I had to duck my head to get in it felt like an old war plane.

It might have been closer to being on time. Maybe next time I could fly from London to Toronto?

Air Canada canceled my flight last minute and I gave me next’s day night time my flight. No accommodations at all. I have a function on Xmas eve. So I had to took rental car last minute.i never ever book a ticket with Canadian airlines at all.

In business on the top-deck of an overnight transatlantic flight. A family with uncontrolled young children were there too. All night they were running around up and down the walkway while squealing . . .

Boarding was weird. They boarded two flights at the same gate at the same time. So mass confusion for the non English/French speakers. So many people at such a small gate. Like every other part of this airport you have to walk miles between everything. Gate to plane was a 5 min walk :) several long flights so I was worried about my steps but ended up walking several miles here so worked out.

The service and food was excellent. The remote control for entertainment did not function properly.

All was good, except my USB charging did not work, so my phone got drained and I could not charge it. Same happened to my neighbour.

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

Everything well done and customer oriented There entertainment system is difficult to navigate

They delayed my flight from Toronto Pearson for one hour and Frankfurt to Abuja for 2HRS, So sad

The aircraft was old, there was no charging sockets, and the seats were narrow and uncomfortable even though I had exit row premium seats.

The service was really good. The breakfast food could’ve been better as I don’t eat sweets for breakfast and the only choice was a muffin. Overall, good experience though. Thank you.

my flight was cancelled. next one scheduled 2 days later. no hotel provided. worst airline experience ever
