They were unable to check my bag through my final destination thus I had to clear customs, secure my checked luggage, and recheck. If the agents had responded to my situation and taken charge, I would have made my connection.

Normally, getting on a plane in Colombia is an absolute nightmare. People pushing, standing right next to you, when you get on the plane all the old women who do not know how to read always walk to the back of the plane when they're supposed to be sitting in seat 7? Been there? Seen that? Yes ! Seen it a million times. What makes this particular flight so unbelievable, and maybe it was just a training day because there was a lot of airline personnel at the check in kiosk, but I have never processed on to a flight in Columbia, given up my baggage, and be walking to the gate so fast in my life! I truly hope this is something that will become standard, and I pray to God that the other airlines especially Viva will learn how to do!

Overall very good, good crew... minus point.. seats SO tiny, it makes Asian airline economy seats feel like 1st class!

My flight to Lima was delayed therefore I would miss the connecting flight to LAX. I learned of the delay by overhearing a conversation the employee was having with another passenger. No announcement was made, no options were presented to help the passengers with connection find a solution until we started demanding a solution. This ordeal started at 9pm and we did not make it out of the airport till 1:50am to a hotel for a 6am pickup back to the airport to start the process all over again.

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.
