No baggage controls from seat 18 to 28 no bags would fit. As we exited all the front rows we're waiting to get there bags stored in back of planes overhead bins. That's just not right, especially when they charge us extra to take a bag for overhead bins storage.

These planes feel like they are made of Legos. They are absurdly tiny and uncomfortable (and I am a small woman). Hot and stinky when boarding and no room for you or your carry on luggage. The days of glamorous air travel seem very far away.

The bag search was very thorough and many employees were wearing their Peru jerseys under their uniforms.

Everything else. Flight was delayed almost four hours with no explanation. Received multiple calls from Avianca but all in Spanish until fifth one in English hung up once we confirmed we understood there was a delay. Staff communicated different directions. Only one cafe to wait in. Substitute breakfast served was underwhelming. Plane was incredibly dated with life vests strewn about/not tucked away. Upon deboarding, incredibly unclear that we had to completely exit and go back through security, meaning we had no time between flights for the restroom or to buy water.

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.
