Long wait for de-Icing. Got on and off the plane 3 times. First wait was 1 hour, but plane aborted takeoff. Second plane waited at gate with all aboard for 2-1/2 hours and never got slot and de-planed. Third plane waited 1-1/2 hours for de-Icing and finally we were headed home. Arrived 8.5 hours after schedule.

As always, the crew and amenities were first rate.

We were initially told that our flight would arrive early. Then we sat on the tarmac for a half hour before anyone could be bothered to tell us we were waiting for the plane to be de-iced.

I was traveling for medical reasons and the Delta crew took great care of me, made sure I was at my connecting gate on time, and even put me in a better seat on the plane. Not sure if that was a coincidental upgrade, or intentional, but it was perfect.

Seats were comfortable ... enough. Boarding process, once underway allowed me to get overhead bin and stash my other luggage in the seat below me. Flight wasn't overly booked (85-95%) so there appeared to be room for others to stretch out. Now about that crying kid...

Ugh. Weather delays. The flight was scheduled to board about 7P but it arrived late and they had to not only unload the self-loading cargo, but clean up afterwards. Would be nice to get a better estimate as to how long it would take to board so that I could hang out in the lounge. In addition, departure from JFK was delayed as well, either we missed the IFR window or got stuck behind some traffic and I fell asleep on the plane only to wake up what seemed an hour later just getting ready to hit V1. No upgrade.

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

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.
