It was on tine

My flight from SFO to SEA-TAC was rescheduled, 4 hrs after the original time, had an hour delay after boarding due to a faulty a/c system. Pretty much ruined the first day my trio.

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.

Even though I was disappointed by not being able to get the boarding passes from Delta for Aeromexico’s connecting flight to Bogota, I had an agent greet me after customs in Mexico to issue the boarding pass so I could use the transfer flight line. Excellent service throughout the entire trip.

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.
