Smooth flying and lots of respects to the pilots for their dedicated work. The entertainment really works very well.

Poor Service. The service of drinks is done very poorly. Really concerned with the attitude. Never need those complimentary drinks.

I did like that "new plane" smell. Good pretzels.

Plane was too new; computer system hadn't been set right. Left 45 minutes late, though made up some lost time in the air. Very rude passengers (obviously not the airline's fault, I know). Everyone thinks they should be the first to get off the plane!

Potable water was down so no coffee, tea, or more important... water to wash hands. Then they didn’t have my second choice of beverages after coffee either.

The cabin crew was great at boarding and organizing the overhead bin space. Also, ground staff didn’t start check roll aboards before the overheads bins were full. There is nothing more frustrating than getting on after forced to gate check your bag to empty bin space (ahem, United at SFO).

Couldn’t get the entertainment to work.

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.

This was my first time flying Porter. The flight was a reasonable price, the service was great. The aircraft was a little on the smaller side but still spacious enough for comfortable travel.

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.

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.

We compile tonnes of data for you
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.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
