It was good delayed again but once on board the flight crew were very good the entertainment and wifi worked on this plane and we were offered snacks and drinks

The second half of terminal C at Hartsfield was 80 something degrees. I was sweating just sitting at the gate.

Seat was too small for someone as tall as I am. I was behind an exit row making my leg room even less. There flights were delayed by multiple hours. Some weather related and others staff related. The plane was hot. Horrible experience.

Flight was delayed and then "they did not have time to load food". No snack or drink at all for 1.5 how flight. Somebody wasn't prepared.

Friendly flight attendant Quick checking for baggage drop Quick TSA lines

It was okay. We were delayed for weather reasons, but the pilots and the flight control staff figured a way around the storm and were able to get us to Los Angeles safely. Not all the staff members were polite, but the entertainment on the flight was good.

So terrible. My flight was 4 hours delayed and we weren't notified til last second within an hour of boarding. WE had to sit on the plane for 4 hours. ridiculous.

Missed the Flight from Atlanta to Roanoke due to initial flight from Houston being 2hr. late. Now waiting 17hrs. till my first available flight.

Internet didn’t work for this leg either. The seat was fine but didn’t have seatback screen, which I knew when I booked it. The biggest letdown is Deltas new policy on beverage/snack service not being served for flights less than 350 miles. I know this is a cost cutting measure, but how much does it really cost to give a drink and a snack for inflated airfare? I really am surprised that with Delta Comfort they don’t provide beverage/snack service given these seats cost extra to purchase. Really need to reconsider this, even if it’s for the Delta Comfort and above.

Did not get a vegetarian option in 1st class and the video was not working.

The personal item sizer cannot take a standard backpack, and the cabin luggage sizer cannot take a standard carry-on. Designed for people from the island of Lilliput!!. and also compels people to pay additional fees to check their bags. Making money by ticking off the passengers is a very short-sighted business strategy, especially since they have a choice of carriers

We got delayed to the point of having a 20 hour layover. That is absurd. I couldn’t believe it. I’m furious.

Delayed boarding. Delayed taking off. Delayed landing. Missed our connecting flight. Our seats on this plane were not assigned until last minute, splitting up our family with kids. I sat in the last row next to the bathroom with so many people rubbing up against me to get to the bathroom the entire flight.

Another delayed flight. Then got bumped to a later connecting flight, over two hours later! Plane was hot and uncomfortable.

Crew was nice especially by North American standards. Bad good. No entertainment screens. Terrible WiFi

Terrible decision to take a night flight. Not enough time to sleep and premium seat has no foot rest ao couldn’t get comfortable!

Westjet is one of the worst airlines in the world. 100% guaranteed to have flight delays and flight cancellations. Will never book again with Westjet.

See review from the other leg San Antonio to Atlanta.. basically the same experience as the flight was operated by Delta.

20+imite delay on the plane with no air. Part of our group had no seats assigned and took a long time to get fixed. Again no wifi and snacks were sad

Flight booked from Montreal via Toronto to Huatulco. Toronto to Huatulco flight was cancelled, lost one day of vacation in Toronto waiting for next flight. Flight from Huatulco to Toronto delayed, missed connection to Montreal. Westjet counter closed. No hotel, no connection flight for 4 days to Montreal to finish the journey. I shall go to Small Claims Court to get compensation for all these troubles. Westjet never again.

It’s a good airline. Polite service and good communication.

We ran into trouble in Montreal. Exited the plane and Air Canada was excellent getting everyone quickly to their destinations. I give Air Canada a 100%.

The flight was delayed and we would have missed our connection. We had to switch to a different airline in another airport

The plane was dirty. It appeared that Air Canada did not know vacuum cleaners had been invented. Second, the overhead bins were about 1/3 or 1/2 the size of "normal" bins. That was a problem. The worst was disembarking in the weather in Montreal. I have cold agglutinin disease. That means my red blood cells clump together and then are destroyed when exposed, even by breathing to cold air. A few seconds of exposure can be dangerous. I am now experiencing extreme fatigue caused by the anemia from that experience. I should have had more assistance descending a narrow ramp and then traversing, even if only a few feet, of icy pavement. The blowing snow penetrated my facial covering and has caused problems.

Nice small trip, No food included in ticket, but beverages were for free.

Entertainment was not working. No free snacks. Seats weren’t comfortable

We were on a Canadian fishing expedition, and Air Canada lost our Sport Fishing Bag. They said it was delayed and said it would be delivered that night, but that never happened, and we haven't seen it yet, which is 5 days later. We had to rent fishing gear to enjoy our trip. We are extremely disappointed with Air Canada oversize luggage personnel. With the sport bad and 6 rods and reels, we are out over $1500.

Very bad flight - delayed by 4 hours little information provided flight crew all stressed

I liked the staff but the plane arrived late to Atlanta and when we landed in Montreal there was a plane already at the arrival gate causing me to miss my flight to London. This resulted in an extra stop in Lyon, France and the airline lost my bag. I arrived finally on the 15th of December and now it is currently the 19th and I still do not even know where my bag is after days of calling and tracking to find it.

The entire boarding process was delayed by a half hour due to the ground crew not being present. The crew was occupied with getting coffee from Starbucks rather than getting on the plane on time. So the flight arrived almost an hour late in Montreal, making several connections virtually impossible. But Air Canada made up a different story in their updates to passengers. Plus there was no person there at the arrival gate to provide wheelchair assistance as promised.
