The flight attendants were pleasant and courteous

The boarding was delayed and the boarding area was crowded, Boarding was delayed due to high number of wheelchair passengers. I was seated in an Even More Space seat, yet was placed beside a woman who was obviously suffering from some degenerative condition, and was slumped over towards my seat. The result was that I was uncomfortable the whole way back to Kingston.

Once again the system for my seat did not work. Fortunately, the middle seat was empty and I wa able to watch that screen.

Entertainment System did not work at my seat. WiFi signal was not strong enough for me to watch any videos on my device.

The departure and arrival times were accurate. Actually we arrived about 15 minutes early.

There was only one individual checking people boarding. Two individuals at the boarding gate would have been even more efficient.

On two of the legs of the trip they notice I was a tall person with long legs and upgraded me to seats with more leg room!! I didn't even ask. Thank you.

On the way back there were open seats with extra leg room and I asked the gate attendant if it was possible to switch my seat to one with more room and they said they only could if I paid extra.

There was a huge glitch in your ticketing, resulting in me confirming the same ticket 3 times. After calling Jetblue for customer service per your advice, they first suggested to give Jetblue credits for extra tickets. When I insisted that the issue was solely caused by kayak-jetblue ticketing connection issues, they supervisor approved to cancel 2 credit card payments... BUT I have to wait for 2 weeks to see the cancellation on my credit card. Unfair and ridiculous, if you as me.

I know it's hard to make a 14+ hour flight in economy enjoyable, but more varied food selections and better/more current movies to choose from would have helped.

Everything. We have flown over 6 flights with Avianca this month. Every single one of them was delayed or cancelled. Not one apology. Not one upgrade. Nothing. We missed 4 days out of our family vacation due to Avianca's terrible service and airline. We went to 3 different offices and called the call center 3 times, we sent 4 emails to no response. Do not fly with them ever.

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,
