I had made a change to my return flight reservation after calling a customer care representative. Nevertheless when I tried to check in for my flight I couldn't do it online and was asked to contact a help desk. There, they couldn't find my reservation for the longest time. After waiting around 45 minutes - 1 hour they were finally able to give me a boarding pass.

I never got to Cabo. It took 2 hours for Delta to de-ice the plane in Milwaukee. Because of the long delay we missed the flight to Cabo. We asked Delta to book us on another flight to get us to Cabo today, Delta reps said nothing was available. Delta gave us a discounted coupon for a hotel in Atlanta and rebooked us on a flight to Cabo tomorrow.

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
