I had to run from the end of terminal one to the end of terminal two to make the connecting flight....probably a kilometer. No electric carts were available. I'm 76 and literally had to run to make the connection at the last minute. The connecting time was absolutely unrealistic. When Last Call was announced, I tried to get other Copa gate staff to call Gate 221 to let them know I was on my way, but they said no. I came within 1 minute of missing the flight.

When Last Call was announced, I tried to get other Copa gate staff to call Gate 221 to let them know I was on my way, but they said no. I came within 1 minute of missing the flight.

I was flying business class, and the French fellow passengers were super noisy. It was not a comfortable flight. And the crew was not helpful.

Boarding was a mess, they call all priority members without distinction so gold, platinum, silver were all mixed together in a long line which defeats the purpose

Entire experience from check in to landing was amazing the flight crew was excellent and friendly. Seats were comfortable.

Avoid at all costs. My wife had to stay back on a connecting flight as her parents flight was delayed. 10 days later on the way back they cancelled all our flights. We had to rebook all four of us on the next days flight.

Friendly crew, good food options, food not the best and seats not as comfy but that’s typical.

The food is terrible I ask for water never got transport my mother we’re late and my sister from Lima was the worst waiting to long for wheelchair

Flight got delayed; had to go through security three times.

Copa staff at PTY and one particular crew member were unhelpful & rude.

Horrible. No TV or any type of entertainment on board. Passwnger listening to/watching stuff on their own phone with no headphones making it noise and uncomfortable for everyone else, little/tiny food portions, old seats, useless wifi (cant access anything). Horrible exlerience especially it was a lomg distance flight with kids.

This was my first time flying with you guys and my very last! This was the most horrible experience!!! There was not even tv in the plane! How cheap can this airline be!!! I paid so much for my suitcase!!! I would never fly with this airline again! The crew are very rude!

The worst experience I've ever had because the "people" @ Avianca wouldn't let me fly because they said I needed a round trip ticket

Seating was tight. Seats don't recline. Initial flight was cancelled. Lost two days of vacation.

I had bad experiences before now was excellent I am glad they have business class again

Provide free food and drinks on an international flight. Add updated head rests

Staff are the rudest in the industry … awful customer service … will never fly Avianca again

Pros: we leave and arrive on time Cons: the most uncomfortable seats ever. You cant recline at all your seats. No entertainment No TVs flight attendants didn't provide even a glass of water. You have to go to back of the airplane and ask for one. I am Colombian and I remember seeing the flight attendants very neat, elegants which is or was a staple of Avianca.it was one with tennis shoes, no male up, the hair was messy... that was really odd.

Last seat of Bussines Class it does recline but passenger seating behind kept pushing since they did not have space once my seat was reclined

I handed in my suitcase in perfect condition at SAL Airport. And in MIA Airport I received it with one corner broken and the wheels bent.

I like the crew members they're very friendly. Clean plane. The flight was on time. I dont like the comfort my car seat its better that the plane seats. They charge for everything. This airline was very good. Now it's a low cost airline
