The flight was on time. Family boarding was super helpful when traveling with a toddler. The plane was clean.

The seat assigned to my daughter had a faulty life jacket and the crew wanted our family to split up. My daughter is 2 and didn't like that her dad was moving somewhere else as we were taking off. Since the crew member didn't want to ask the individual sitting next to me, I asked if she would mind moving so that our family could stay together.

With over an hour in line to enter the International portion of the airport everyone was extremely stressed. Immigration personal were very snappy and rude (Not Avianca, Colombia). We had over an hour wait to get inside then it was a long run to get the the gate on time. The problems that Avianca is having with its flights, on time percentage and upset passengers is very Sad. Normally Avianca is the best airline in the American Zone! They need to fix their internal problems quickly or their bottom line will get punished.

Avianca overbooked the flight by 10 passengers. They would not board the flight until they got 10 volunteers to except only $240 voucher for delaying their flight by one day. It took them three hours to accomplish that. The hot food had been delivered on time to the plane, so that also sat for three hours. By the time it was served during the flight it had turned to rubber. This was all together a dreadful experience. We missed our connecting flight in Los Angeles and Avianca airlines provided no help on that. .

*
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. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
