The earlier flight departure times are really good, the traffic is not jammed yet on the 401 and GEW. Custom waiting times are basically non existing in comparison to Pearson. Planes are relatively on time (only flew 4 times with Porte), staff is friendly. The turboprop planes have more legroom than most others. I do like them, and do recommend Porter.

It was overall a good experience, cannot complain about the service as it was great.

The weather caused a bumpy return flight but that is not the airlines fault.

Compared to the flight going the other way, this one was much more comfortable. I didn't have someone's seat back in my face the whole time, and was able to enjoy games on my own device. I like that both USB and normal power options were available, so I was able to play games and charge my phone so I could use it after landing. The food was passable as well, which was surprising.

It's unavoidable when flying between multi-lingual locations, but having movies and stuff pause three times for each announcement gets annoying. The rolls served with the meals were very dry. These are small nits, and the flight was generally enjoyable.

Mediocre 3.3

The baggage checkin was awful. The boarding check in was awful. The security check in was awful. The customs check in was awful. Understaffed and inefficient. The baggage conveyor backed up. The same staff that checked in our baggage was the same person who then ran upstairs to check us in at gate and it was all hand done and not computer scanned. No check in kiosks to make ticket checkin faster. Lines were all backed up and I barely made flight and my connection. Many either missed flights it connection or plane was held up to get people to flights. The lady at customs check in was good trying to handle the back ups but the shrine was severely backed up and understaffed. The pilots made good time and handle the turbulence well. Staff on board did well with timing of food and drinks Entertainment on board was awful. Didn't find out until on board on 8 hour international flight that needed an iPad with downloaded app for entertainment and therefore I had three kids that had nothing to do. Never did I have such an issue with an international flight that was so poorly managed. So disappointed.

I love the variety of entertainment, it never fails.

I didnt like how snacks werent included for my 6 hour flght. Also the amount of waste made with all those plastic cups is astonishingly ridiculous. Switch to a more green solution!!!

One of the crewmembers (regrettably, I did not catch his name) was incredibly kind when I moved seats to accommodate a couple that wanted to sit together. He really made this flight great.

Seats were comfortable but the row I moved to did not allow me to recline.

Crew overworked but pleasant and doing their best. Self check in works well with assistance

Management decisions meant assigned crew arrived after our flight supposed to depart. Needed 1 more person to service passengers. We waited a long time after serving started to get served. We did not know that food could be preordered online and served soon after takeoff. No TV screens on back of chairs...had to rent device to see movies. Have app but not able to book and get points. Wrote to WJ for help but oo response

I have flown on Porter numerous time but this was the first for my family. They enjoyed the Porter lounge and convenience of flying from the Toronto island right into EWR. We were able to take the NJ Train right to Penn Station (NYC) faster than any taxi.

Told that due to turbulence, no cart service would be available. There didn't seem to be a whole lot of turbulence that would prevent cart service. We did get a bag of terra chips and a small water.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
