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.

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.

I almost missed my connection. No one cared. Staff in airport were downright cranky - all due to late incoming aircraft and yet more de-icing... why ever don't they allow time for that in November!!!

The waiting area at the Boston airport is poor. It is very small, rundown and with limited access to refreshments. It's ok but certainly not a selling point.

Boarding and flight were fairly smooth, the crew were friendly and the seats were comfortable.

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.

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.
