Overall it was another positive experience and great value.

Flight attendant told me I couldn’t sit in the exit row because I chose to wear a seatbelt extension. Is this a new rule? I’ve sat there many times without an issue. I can perform all the functions needed to open the exit hatch and help people escape. Why does being a little more comfortable mean I can’t sit there? The seat belt comes off the same way. What am I missing? I moved without questioning her but the rule, if there is one, makes no sence.

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.

Not a single part has a positive remark

Well - this partner of westjet was terrible. The amount of re direction to get to the final terminal was absurd .. that's just my venting My real problem is that then "crew" or team that represent s the American Airlines / compass part was just useless. A hand full of people - myself included didn't get a chance to board the plane as they didn't make any announcements. Beyond disappointing. When you check in they take your cell phone "in case " well no call no txt no nothing. It was a joke the level of service No apologies or anything just a group of any tired patrons getting the worst customer experience. I'll never EVER book a flight that has anything to do with American Airlines or its partners

The scheduled plane had a mechanical problem so we deplaned for alternative plan. It took six long hours to get another plane in. Meantime passengers stood in line for hours to make other arrangements. It would have been appropriate for the airline to call in extra staff to help stranded passengers. We missed the scheduled connecting flight and a tour. We got in at 1:00 am, 12 hours later than planned. We had meetings next day and were very tired because we got in so late

Considerate flight attendants. Turned lights down for evening flight, so we could get some rest.

Flight was not on time. Time was changed a day prior with no reason explained. No in flight entertainment on this flight.

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.

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.

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.

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.
