I find Air Canada has the most options but isn’t always the cheapest. The flight is quick and easy. If you can fly later at night, I would because your commute to your final destination will also be quick and easy.

If leaving from Halifax, I always give at least 30-45 mins extra as I find security there extremely bad. In addition depending on the time of year there are less companies who fly in the off (winter) season. That leaves Air Canada and Porter. Their fares are comparable usually.

Checking luggage can be done online 24 hours before flight departure and you receive your boarding tickets. Both save you time Bring snacks in the plane. Anything you buy in the duty free zone you can bring with you when you board the plane, even restaurants left-overs

Board early so you can actually secure a spot for your carry-on items near your seat. There's an $11 express bus from the airport to a major subway station downtown (and includes free transit service in the city for 24h), but the bus only takes exact change, so make sure you buy a ticket from the kiosk in the airport first.

If there is a connecting flight to the US register with the MCP app or have Nexus. Only 2 US customs stations open for a lot of people to check. Everyone was running to their flights. We had 2 hours in between our flights and we got thru just in time to board.

Boarding pass counter did not open until 2 hrs before flight. We were there 3 hrs before as we like to be early ( eat, relax etc). Due to this the line up was large , thus never got through security till 15 min before boarding. Other than that, everything was great

We were very offended Reserva check in agent in Calgary. Erroneously profiled and reprimanded for using Reserve line . Hadn't even looked at tickets. We were in fact Reserve passengers

Even tho the flight was a bit delayed the team was apologetic. Everyone was friendly and efficient.

On my e-boarding pass it shows free wifi, yet the plane I was on didn’t have wifi. Please remove false advertising from your website and boarding passes

Smaller plane. Food and bar service for free is amazing. Drinks were in glass not plastic cups.

I was not happy with AirfareAssist, the agency that kayak advised me would be handling my booking. I was advised by porter airlines that I had been overcharged for the Basic express , a option that I had asked airfare assist to help arrange after I realized that the basic fare I had chosen with porter did not include a carryon. At each checkin porter advised I had been overcharged for this . They advised that money would be refunded to my credit card, however, this is not likely to happen as it is not my name and credit card that appeared on the porter invoice, but that of another individual/agent. When airfare assist was arranging the basic express with porter on my behalf, they asked me to confirm that I agreed to pay $263 USD for this. I did agree, as I was advised this was needed to proceed. When I checked the invoice on the porter website and saw that it was not my name and credit card on the invoice, I was advised that this was how airfareassist processed the payment. The Porter invoice indicated a billed amount of $126USD I will not use Kayak or their designated AirfareAssist again

Everything was good except the fact you charge more for a carry on bag vs a check in bag and to top it off in US$ that was not impressive

Our flight was cancelled at the last minute for maintenance reasons and we were rebooked on a late flight when we purposefully booked our flight to be home early due to work.

Seemed like an old plane. Very noisy. The seat cushions were so old that the metal bracing of the seats were poking through. There was plenty of leg room though.

The whole experience from check in to deboarding was fantastic.

My screen was broken so now movies, etc, but I didn’t really mind. They did work on it, so good effort on their part.

i was not able to take my flight because the information i needed to book my dog correctly was not provided

They never sent me a confirmation to say my flight time had changed so I cut my holiday short by 6 hours Had to pay over 50 American for my luggage to be checked on the way home and that’s more that it cost on the way there. Arbitrarily charging more for the same thing when the passenger has no options is shady The cabin was an icebox going there and back, if all the passengers have their gloves on and their hoods up that should be an obvious sign to turn up the heat

The Turkish was good . I had a problem with air Transat terrible experience for me

Porter airlines was good. I didn't have the best experience when booking through airfare assist however, as I got no final confirmation from them that the flight was booked until I called them. Even then, the confirmation code they gave me was incorrect and couldn't be used for check in. On a positive note airfare assist was actually picked up the phone relatively quickly when calling

The flight crew were very good, polite, and professional. Unfortunately, the rest of the experience left much to be desired. The food was extremely bland—almost tasteless. We chose the non vegetarian .The lasagna was just plain pasta with a tiny garnish and no seasoning. It felt like eating starch only, The bigger issue was with luggage and space. We boarded with three tickets, and while the seats in front of us were nearly empty, all the overhead compartments had already been filled by passengers boarding to the back. This left us and many others with no overhead storage for our carry-ons. Our bags couldn’t fit well under the seats either, which meant we lost the little legroom we had. The result was a horrible, cramped experience—sore knees, no space to stretch, and no way to rest or sleep comfortably. According to the crew this was a rather normal thing. It is obviously normal that people board with handbag and carry on but they should be only allowed to use their overhead compartment and under their seat not the way it is managed that all the spaces in the front of the plane being occupied by the people sitting way back in the plane.

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.

Not so much porter it's your site! Not good

The connecting flight lay over was 4.00 hours, the gate agent booked me on the next flight which was about to depart at no extra cost.

I think as another discount flyer they stepped up the bar. I think they should stay around for awhile

I didn’t have any food but my Prosecco hit the spot. We left on time and the crew was friendly.

I wasn’t able to book or pay for a seat and they forgot to check me in for my third flight so I spent 24 hours in Toronto waiting for another one.

I like the wider seats, Plus lots of legroom, Lacking entertainment, no tv or screen to play with

The keg from Edmonton to Toronto My wife found it very cold. Other than that great flight.

Flight itself good .Landing at terminal3 and connections to terminal1,it is connections nightmare,specially for disable person

The seats very Uncomfortable, no meal and no entertainment for a 4Hours flight. Smooth Flight, Great Take off and landing. Superb crew!

It was good, flight was on time, boarding was smooth and done in zones, food was good too but there was no form of entertainment. Luggage’s were intact. So an overall good flight

Too squished in seats. I'm 110 lbs and 5'6....can't imagine being any bigger and flying

Original flight canceled and communicated poorly. A series of gate changes , delays and plane changes followed. Even after the entire flight boarded there was another plane changes followed. Food vouchers provided to my travel companion but not to me despite being on the same reservation. No in flight entertainment. The entire experience was terrible although the flight crew were great.

Check in agent was good, stewardess was unfriendly and certainly did not have the care of the passengers in mind Spent the whole time on her phone

Flight was late missed our connection to Indianapolis no hotel rooms really difficult finding a room hope to be in Indianapolis one day late and multiple flights to even get there.

No charger and no entertainment on the way back. The plane's super old-like 80s old-with zero TVs. At least the free Wi-Fi works, so definitely bring your iPad. Also, no meal on this 7-hour flight.

I have flown this route before, so far they have been unable to depart on time, then my connecting flight was canceled, likely due to this vs fake mechanical issues

Cancelled flight, had to rearrange plans independently and no vouchers offered

My experience was good. On my return my screen had a glitch but the movie, show and internet options were good. Seats were comfortable, as comfortable as a plane could get in economy. Friendly service. Only complaint would be high price.

Every flight was canceled and they didn’t care much about their passengers

this flight was exceptional due to the plane itself being updated with longer seat belts so no need for the extender and access to a tv.

Comfortable seats with good leg room. But not screens on seat backs.

Air Canada has very professional , friendly and co operative crew.

I liked the fact that we arrived on time. What I did not like, I paid for a seat. Unfortunately a very large women sat beside me (required a belt extension). Her body spilled to my side. Not her fault but I had to lean to the left because her body was literally on my side of the seat. This caused a back ache. I was unable to sit straight the entire flight. There should be some form allowance (wider seat) for morbidly obese passengers. These seats are not designed for extremely obese people. I feel compassionate towards these obese passengers but I got off the plane with a substantial lower back ache. I myself have a degenerative disk disease and this did not help me

Their "free personal" requirement is to have your bag fit in a containment frame that is way too narrow and slender than the space under the actual plane seat (the length of my vitamin water was longer than the width of the containment frame. They had personel at the gate literally designated to hounding people's bags in the zone line up, and forcing them to measure their bag again if he felt "the bag might be too big for personal item". If your bag was too big for their scamming measurement criteria you had to fork up $110 CAD for the carry on cost ($85 at the 24hr online pre-check in). Plane had no entertainment, seats did not recline, and no complimentary snacks or drinks. Unless I have a short flight with zero bags, I won't be flying Flair ever again.

Flight attendant said bye bud. Lol peak flair right there

On time flight. Reasonably comfortable seats. Disliked having to pay for refreshment and snacks.

Not good Even after I made my booking, I was charged $90 for my boarding pass. I have collected boarding pass i pay $90 near . Flair airline not good. Without pay no boarding pass.

Personally, I will not use this fight again. The service is poor, you have to buy even water. They don't provide anything even sneak, you have to buy. They said Personally items for 7 kg. Then they use some measurements, if you have 7kg and if it's not getting inside of their measurements, you have to pay 80$ this is robbery. I will prefer other flight then this. I am désappointement taking this airplane.

It’s a shameful company. It ask as to go to counter to take the boarding pass, they simply send it by email, just to check the bags’ size in a smaller than normal template. DONT USE FLAIR! It will be more expensive than normal airlines at the end.

The flight was safe (priority). Everything else is low-cost: too hard, delays, mediocre boarding, cost for carry-on and checked luggage.

Flair did not notify you when they changed gate number!

There was no entertainment There was no food or beverage service , not even a glass of water The plane door could not be opened upon arrival

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