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.

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 ?

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,
please send us an and someone from our team will get back to you promptly.
