Long delay die to pet mix up. Also bags took forever to get to carousel

Pros: "Crew did the best they could under the conditions"
Cons: "There was a broken toilet that was very loud and created long line ups because economy only had use of the 1 bathroom while the first class had 2 bathrooms for so few people"
Pros: "Crew and staff at gate fantastic. Accommodated me sitting with partner on both legs (booked flights separately)."
Cons: "Flight was delayed. Always tough late at night."
Pros: "flight was fine and on time, this leg of my trip was easy"
Pros: "All westjet workers are amazing. Starting from the people at the front desk, the crews on the plan and the people that give direction."
Pros: "Good crew and on time departure"
Cons: "Overnight flight. How nice it would have been to have blanket and pillows as provided by some airlines ."
Pros: "The attendant didn’t take any chance on rainy whether condition and got me on an earlyer flight to make sure I wasn’t goinig to miss my connections flights. It worked out perfectly."
Cons: "Everything was perfect. Thank you"
Cons: "Delays left us in the plane for almost 1 1/2 hours before leaving Toronto."
Pros: "Good price for long haul destination. Efficient check-in and boarding process. Decent leg room for a budget airline."
Cons: "Food choice a bit limited - especially the free offering. In-flight entertainment is only available from the WestJet app to view on your own device - you need to know this before you board - otherwise you are not able to access any of the movies etc."
Pros: "Joesph air host was amazing! Took care of numerous people with kindness & professionalism on our morning fright from Toronto to Vegas!"
Cons: "Lots of kids on the flight. Parents did a great job coupled with the staff. I very grateful! I needed a nap ! Iol"

Porter, like most airlines, need to improve their baggage policies. In reality, there are no longer 'cheap flights' because passengers pay exorbitant baggage fees.

Pros: "Amy was outstanding, she provided excellent service."
Cons: "I wasn’t notified that the basic fare didn’t include carry-on baggage. It was disappointing having to pay for checked baggage without notification."
Pros: "Really like the wine and chips included."
Cons: "No entertainment options, but not a big deal considering how short all their routes are."
Pros: "The cookies"
Cons: "They bumped our flight for no reason and we sat for 3 extra hours in Toronto as several flights to our destination passed"
Pros: "Beverages and variety of snacks on such a short flight - impressive"
Pros: "On time, loved the Porter Lounge at Billy Bishop. Crew was friendly and helpful."
Cons: "Didn’t realize that my fare didn’t include carryon, so had to pay extra to bring my briefcase."
Pros: "Nothing whatsoever!"
Cons: "Received e-mail about flight being cancelled on way to airport and could not get us on another flight for 4 hours. The cancellation was incredibly last minute and caused us to be stuck waiting in the airport almost 6 hours as the flight we got rebooked on was also delayed about an hour. The incredibly rude, unsympathetic and condescending associates that we experienced did not offer any solutions or show any compassion for the situation we, and others, were being put through. I will never fly Porter again and have told everyone I meet (and in my profession, that is a lot of people) never to fly Porter airlines. I was disgusted by the whole experienced. Shame on you!"
Pros: "First time in 10 flights in 3 months flying with Porter in time - what a miracle!"
Cons: "Original flight cancelled. Missed connection in Toronto. Rebooked flight was delayed departing Ottawa. Layover of 2 hours in Toronto. Flight to Windsor delayed as arrival from Montreal was late. 7:30 pm departure now delayed to 8:15 pm departure. I could have drived Ottawa to Windsor in same amount of time. Total waste of money! Still waiting at lounge in Billy Bishop Airport as I write this. And the weather was perfect today! What’s going on?"
Pros: "The crew was friendly and welcoming"
Cons: "Our flight was delayed once again. Once we landed our carry on baggage was not given to us right away. We were told to wait for it outside the plane. After waiting, we were told we would have to pick it up at the baggage carousel with the checked luggage. We had to wait over 30 minutes for our carry on luggage."

One United employee a little impatient, also on flight WiFi was out for some time. I was happy to receive a complimentary alcoholic beverage for volunteering to check my carry on bag.

Very rushed and stressful Transfer at Pearson. Baggage delayed, I have been advised is coming, but not sure when.

Boarding was a breeze and the attendants at the airport were very helpful

Not to long of a trip, crew where very good.

Took forever to board. Didn't leave until an hour past scheduled time.

Pros: "Amazing crew and Ground staff. Check in and bag check in was really smooth and fast."
Cons: "Maybe some more options of snacks. In flight entertainment was not working so can’t say much about it."
Pros: "It's a direct flight."
Cons: "Everything - the plane was last updated in 1989 (you can still see where the cathode ray screens were bolted to the central overhead bins), the entertainment is laughable, several didn't work - passengers were given choice of putting up with that or getting off flight. A flight to endure, not enjoy"
Pros: "The seat was fine for economy"
Cons: "You should offer free wifi! Air Canada should lead the way and be above the rest!"
Pros: "The crew was friendly and tried to provide a good service."
Cons: "Wider seats and more leg room. The return trip from Ottawa to Vancouver was over $1200. I think that’s quite pricey given that any food or alcoholic beverage had to be purchased at an extra cost."
Cons: "There was no coffee or tea available on the flight"

Seats suck. Only one drink service in three hours with the flight attendants being more attendant to their phones than the customer. Painful in the extreme.

Pros: "The boarding and deplaning were well organized and handled very professionally"
Cons: "I had an aisle seat that was hard as a rock. The cabin crew repeatedly slammed into my shoulder with their hips and carts and never once excused themselves or asked if I was okay. The PA was muddy and difficult (near impossible) to understand."
Cons: "Last minute plane change due to incomplete repairs was a bummer, but I appreciate that they caught the issue before we took off"
Pros: "..."
Cons: "I got stuck in the airport through the whole night"
Pros: "The lady at the checkin was very considerate and suggested that I am only allowed to bring one baggage. So she suggested if I can combine my both luggage as one, then I should be all good otherwise they will charge double- scary."
Cons: "Light travellers like us should be given more latitude to choose 1 bag size 17x10x 5” and one laptop bag size 12” X 10” x 3”"
Pros: "Boarding"
Cons: "Direct tv sucks! Had to watch trailer 3 times before movie started. If switched to another movie it started part way. Flight attendants instead of one long announcement made three announcements few seconds between thus cutting in and out of movie."
Pros: "The crew was friendly and helpful."
Cons: "Better snacks would be nice, and there was no entertainment available, even for personal devices."
Cons: "It took 45 minutes for the luggage to arrive at the carousel, and they sent it to the wrong carousel. Not sure if it was at the other one the whole time, or just took that long."
Pros: "Everything went smoothly, AND the flight was pretty empty so I got to spread out over 3 seats to sleep. A treat!"
Pros: "Steward and Stewardess very nice and helpful"
Cons: "Walk between flights was extreme - tracked at about a mile! The video movie was incredibly choppy making entertainment frustrating."

I don't like anything. The crew was so bad. Misbehaved badly. The worst flight.

Long wait for baggage check in with only one on site attendant.

The worst airlines I have seen in my life they don’t respect anyone they don’t care about anyone they lost our luggage and no one is responding. We waited for five hours to get our luggage back.🤬🤬🤬👎🏻👎🏻👎🏻👎🏻

Great staff. Cramped seating for someone 5 feet, 2 inches and average weight. So if you're tall or heavy -- good luck. Even if you wait until the 24 hour checkin time, you still charge for seating. Really? So either it is a less-than-pleasant experience or pay the price of a "big name" airline. And if I'm going to pay their prices, why would I fly in your cramped seat? So, in the end, you want to give less comfort for the same prices as Air Canada. Go figure.

The airplane smokes and they think it's normal.... this is sign of deterioration

Flair aircraft smokes before takeoff... and this seem normal to air hostess..... smoking aircraft is not a good sign of safety

Flair’s customer service isn’t helpful at all and their refund is a scam

Everything was great. Got out 5 minutes early and had a nap on the overnight flight.

Wifi was down on this flight but I had a movie downloaded.

Horrific airline. This trip didn't even happen!! We got to the airport and were told at check-in that our tickets were canceled WITHOUT NOTICE! I begged the agents for more info and was told we were blacklisted for using a fraudulent credit card. The card was debit and the funds were already taken out! The desk agents all left, and we were left with zero solution. We had to book another flight with a different airline which cost us $2300 in addition to the $550 Flair already took from us. I have been on the line for 30 minutes to speak to an agent. Does not look promising. AVOID FLAIR AT ALL COSTS.
