We arrived on time.

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.

Left and arrived on time. Crew was friendly and professional.

Passengers are packed in like sardines. All carry on bags must be checked at the gate as the overhead bins are too small to accommodate anything except a small personal bag or jacket.

The crew was nice, quick check ins and boarding. They were very accommodating during the flight.

Although it was breakfast, not everyone wants sausage or the other option of fruit and yogurt. Meals should be offered in the literature provided by time, as in reality, if you're not going to sever the expansive US menu throughout the day. I was unable to order a salad at 9 am, regardless of being starving. Also I'm 5'1, there isn't enough leg room. Power outlets should not be a first class luxury, that is rediculous. We all need to charge our devices. TV should not come as an extra charge.

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,
