No vegetarian options in first class.. and go go wouldn5 hook up. Flight was an hour late...but that was ok.

The pilot did a nice job of flying in and banking so we could see the view..

Entertainment and crew were great- comfortable seats, got to watch a couple of movies with headphones provided by Delta; forgot mine so I assumed I would be miserable thru the whole 4 hour flight. so glad I was wrong! Would definitely take another flight with Delta... looking into the frequent flyer program as we speak

The Delta check-in at RDU was terribly understaffed with only 2 agents handling baggage drop-off for a fully booked Boeing 757. I waited over 1 hour and got to the gate at the last minute. Poorly managed! The flight crew was great though! Very attentive service even in the economy class!

The food could be better.

Good 6.0

Staff were friendly and attentive. Boarding was good - efficient and quick.

Seats were not that comfortable. Aircraft very noisy. Competition offers a much better service. Transfer in Atlanta was a nightmare, taking almost two hours from landing to getting to the domestic gate for the next sector. only three immigration staff working.

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,
