3.5 hr delay for a 1 hr work flight. No information as to why the delay until 20 mins before boarding.

Organization and the adjusted times but the snacks could be of a bigger portion

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

Poor landing as we overshot the runway and had to re land the plane. Lost both of my luggage not found as of yet. Had to pay extra money for my luggage in USD, now great my luggage is gone. Will not fly with Porter again.

This flight to St. Johns was really good. Boarding was a breeze. We left spot on time. Seats were actually pretty good. Recliner further than I expected. Three more flights to go we will see if this is the status quo for Porter.👍

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

Our flight was delayed by a bit. I appreciated that we were kept informed on why periodically. Boarding was fine. I overheard one flight attendant sounding very rude to a passenger who was not paying attention to the safety demonstration. The snacks were minimal as it was a short flight. There was no entertainment. Overall the flight was good back to LGA.

There was a 5 hour delay. Missed connection and now an almost 21 hour lay over!

The flight was fine see earlier note for the problem

All good the seats a little tight and no I pad screen

Flight delayed missed connecting flight crew not very helpful very frustrating customer service

Our biggest complaint was a major schedule change that was not communicated to us in any way. Luckily the time change went later not earlier so we did not miss the flight. Our email addresses and phone numbers were on file but we received no email no text message no nothing. Short flight so not much to say.

Airplane is too small. Crew, especially the flight attendant who looked after our area, was not at all friendly and a touch authoratative. She may have been the most gruff flight attendant i've come across in 40 years of business travel

I when to Jamaica for my dad funeral and I did not get my luggage from westjet . I add to buy clothes putting me financial debt i did no want to be in Westjet did not call me to apologize are to inquire about my luggage I am still angry about it

Ground staff was not helpful, but staff at the business counter were excellent.

I selected "carry-on" for a round trip on Kayak, but my return flight on WestJet did not include a carry-on and they would not allow me to add one. My only option was to add a "checked bag" which I had to wait for on the luggage carousel after landing. Not a good experience.

The plug in to charge our phones are all loose my block would not stay in!!

My flight was cancelled due to weather but Westjet got me on a new flight in a timely and efficient manor.

It was disappointing to see the huge number of people who were allowed to board who were claiming to either be disabled or needed extra time to board who practically ran to the gate as soon as boarding opened. One of the female flight attendants in the premium economy section refused to let a lady with an infant use the toilet next to row 9 to change her baby even though the path back to the rear toilets was blocked by staff and trolleys and said she would have to carry the baby to the toilet during the descent phase when turbulence was present. The passenger refused and the baby had to wait until landing. It would have been no problem to allow this infringement of weathers petty rules. The flight was also very cold due to a cold draft throughout the flight from the bulkhead ceiling which was not controllable.

Food good . No entertainment. Need to use wifi to access your own apps. Eg Amazon Prime, YouTube. They don't tell you unless you ask.

I would like to review the next flight from Toronto to Fort Myers as it was a disaster!!

This flight with a lot empty place , and I have more room, feeling comfortable.

It's kindof ridiculous that your system is even asking me about this since my flight was canceled and I wasn't rescheduled.

Flight was cancelled. Not enough agents to deal with the people in the line. We left and found our own way to Vancouver.

Flight was good, breakfast could be much better. We had come from a domestic flight on the same aircraft and the domestic flight was much better regarding service compared to this international flight.

Flight was great. Meal was really good. Boarding was terrible. Too many people in a small boarding lounge, zones not clearly marked.

3 hr delay at the gate while they were doing maintenance. Next time, do not board passengers while maintenance is being performed

Digital check in is very poor with air canada compaired to other airlines

Flight was delayed 3 times. My luggage was sent to Saskatoon instead of Casablanca - airline got it sorted out in two days. Received $45 in meal vouchers to use in the airport.

Seats were so small. I’m 6ft and a good 20% of me hung out into the aisle and the flight attendants come dashing with the cart. On multiple occasions they hit me before saying mind your elbows and knees. I’m like, yes, but where do i put them. There isn’t a space that exists that i can fold into. The carts are so close to the seats when they pass through that i regularly felt water dripping on me as they poured drinks. Overall 3/10 experience. Highly unlikely to recommend
