We had a great flight just wished they had a tv so we can see a movie that would of made my trip excellent.

The flighr attandants were very rude they ignored me didnt offer me anything to drink throughoit the 4 hour flight i feel i was targeted and ignored because i was a darkskin latino man.

Very happy with my flight. I would definitely recommend it.

Seats not reclining, no vegetarian food option, no snacks. 7.5 hr flight should have been more comfortable. Luggage limits are unusually small. Will never fly Copa again and will tell friends and family to avoid this airline.

We paid extra with copa for seats near one another The plane was changed and we lost our seats We were all Separated. We have not received a refund for our seats despite emailing and calling.

We had a five hour layover in the way home from Colombia. I read the "bout your flight" email carefully before we checked bags. We had to go through security right at the gate. Almost lost our ground coffee because that airport only allows 16 ounce of coffee and we had 18. I've been to 48 countries and never heard of a coffee restriction. I can't follow a rule I don't know about. I requested they bring our coffee to our checked luggage. Instead tey gate checked our bag for free. Back to planning transfers in Dallas I guess

Tell people to remain in their seats during the meal/beverage distribution. Enforce boarding by group numbers. No one was checking. Tell people to turn their electronics speakers off. Bigger cups for drinks.

Enforce the boarding process by group numbers. Tell people to stay seated during the meal/drink distribution. It took forever to get food and drinks because people would not stay out the isle and let the crew do their jobs. Everyone wanted to go to the bathroom forcing the crew to enter and leave the isle constantly so people can pass. Tell people to keep their electronics off speaker mode. No one wants to hear phone conversations and music playing.

There was no individual at the front check in when I arrived. I waited for at least 15 minutes and walked around asking security/janitors if they could help and they did not have a solution. So I had to take my checked bag through security and they threw away some of my items. I ended up making it to the gate only a few minutes before it closed due to my waiting for an agent at check in.

The flight was delayed twice and I could not speak with anyone at the airport about checking in. The phone number to Copa - the customer service agents were polite. They are just limited at helping because they are not at the airport

Very uncomfortable planes , poor service on the plane , take your own water so you don’t dehydrate , in a 6 hs flight they sold one time food and beverage . 1 plane was delayed 6 hs , I lost a connecting flight . Then in the way back they announce a delay of 2 hs so I had to take a different flight to arrive on time for my connecting flight . Avoid this airline .

Avianca is not what it used to be. So disappointing

It was horrible. My experience with Avianca. I didn’t know it was Pakistan international Airlines but anyway, whatever it is it is bad horrible you guys need to upgrade everything in those planes. And you guys charge $130 for a carry-on did they wanna let me in with my carry-on that I travel everywhere with the luggage you guys are such a dog thank you

Flight to Bogotá delayed by 3 h Missed connection from Bogotá to Guayaquil. Avianca unable to bring us to Baltra on time Overall delay 36h. We missed boat departure from galagos. Overall 10 day trip needed to be cancelled. Avianca was completely un-professional.

I receive a service for what I pay, so it is fair.

i think the flight was late because they were so strict about measuring everyone's personal items to try and charge them $119. It was really petty and made us late.

Terrible, We had to stay in Bogota for two days due to weather but the airline did not provide for the same day flight. Only two days later

Business class seats did not lie flat. There was only powdered milk for your coffee....in Business Class!! Food was good.

We did not know about the bag fees until check in. They are way too high. It’s insane. We also had a huge delay and everything costed extra which was very annoying.

Boarding was somewhat confusing in that the wrong messages were being displayed at the gate. It was somewhat annoying that I got off one flight and straight onto another (from the same gate), but in between they re-checked my hand luggage and made me get rid of my water (which they charge for on the plane). I was sitting in their 'Plus' seating, but the leg room was still too small to be able to sit square. The food options on the flights are pretty cheap quality (but not price). They got me from 'A' to 'B' on-time and for a relatively good price, but the experience itself was below average.
