The checkin supervisor at Ohare gave me a hard time given that am the only checking in. I felt I was profiled. Very unprofessional

I guess I can't expect much from what seems to be a low budget airline. The food was OK and the movie selection was excellent. I didn't have any issues with boarding or baggage check in. There was a mix of good and bad flight staff. Sadly, the staff in bad moods were servicing me.

The bad mood in-flight staff and the uncomfortable seats. During boarding, I asked one of the staff if I can have a window seat because I have motion sickness and aisle seats make me feel ill. She looked at me flustered and said all seats are booked and that I'll be Ok with the aisle seat. On a different CP flight, a different staff was helping a couple switch with other passengers so they can sit next to each other. That would have been nice if they did that for me when I asked for a window seat.

The crew is nice. You can order snacks in between meals.

Our flight was cancelled and we were automatically placed on another EARLIER flight and we weren't notified. I found out the morning of our original flight, as our new flight was about to board. I still haven't figured out who was responsible for this snafu - the airline or Webjet.com. Webjet customer service was horrible and offensive when I tried to explain to them what happened; they said it was my responsibility to check the time. I would disagree - the customer is ultimately supposed to get an email notifying them of the flight change, giving them options. Based on that phone call with Webjet, I will NEVER do business with them again. As for the flight cancellation issue - if Kayak could help me get to the bottom of this, that would be appreciated.

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.

Nothing, they didn’t care about you or to help, the llady was so rude and unfriendly, this situation ruin my whole trip

I call in advance to paid the fees for baggage, I call Aeromexico because was the main airline for the fly, but Delta at Seattle made me paid again the fees for baggage’s even by phone they said that I didn’t need to paid. BE AWARE AND CAREFUL BECAUSE THE LADIES IN THE FRONT DESK didn’t even look the paperwork that you have in hand, they only want to charge you saying that your payment thru Aeromexico didn’t help you in the 1st fly. How this can happen when Delta and Aeromexico are two subsidiary one of another ?

Not sure who thought every passenger is 5'6 but for the rest of us, the seat pitch is ridiculously close. Like knees to the seat in front close. I'm 5'10 and I was very uncomfortable the entire flight.

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.

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,
