the food served was an embarrassment. No connection for charging the cellphone... What a crappy airline.

the food served was an embarrassment. No connection for charging the cellphone... What a crappy airline.

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

Did upgrade, travel in business it was great (more room I could sleep)

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 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.

Placed us in the last rear row of the plane so could not recline seats because of the rear wall, and also made it more of a tight space when the passenger in front reclined their seat. While understand seat assignments, every passenger should be afforded a reclining seat. The odor control scent from the restrooms was overwhelming strong. My wife and I could not deal with it, and she suffered a terrible headache as a result. I kept getting hit by the crew since I was on the ilse seat. No apologies, nothing. They made me feel like I was supposed to take the beating for a 3 hr flight.

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

It would have been better if they don't separate families in seating. We were seated in the aile row in the middle of a family of four. It would have been better if they they seat the family of four together than separated.

3 hour weather delay followed by 1 hour (and counting) maintenance delay. UGH!

After we'd boarded , they canceled the flight. The crew didn't even know , we just all received text messages. Then after they deplaned us , AA was just like "too bad, go F your self, we sure ain't gonna help you"

After a two hour delay, my flight was CANCELLED! No pilot available. Such BS.

Amazing food, great staff, with one noticable detail missing ...but no seat entertainment in any of aircraft ...I am not a fan

I wish American Airlines would change the airline industry by loading the plane back to front instead of front to back. Planes would board so much more smoothly and quickly.

I have long legs, my foot was out in the aisle and when a flight attendant came walking by and I didn't notice, instead of saying "excuse me" or anything like that, she kicked my foot. Extremely rude

Excellent! The gate agents were kind enough to rebook me on an earlier flight saving me from a 6 hour layover. Even my luggage made it despite the fact that the connection was technically too narrow. The flight itself was very comfortable, roomy, and clean. Plenty of space for my carryon items with plugs to charge my phone. After a long international flight of 14 hours, this was an excellent way to end my travels!

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

This particular flight wasn't very full at the back, so there were three seats available for spreading out and getting relatively comfortable

Most of the delay was due to weather which is not what was at issue here. One delay was due to a missing flashlight and in the end the flashlight was actually found on the plane. The entertainment system is very limited. Live TV options offer only a few channels that are not very appealing. Boarding and deplaning are always difficult. It just takes too much time to get on and off the plane. On the plus side, I missed my connecting flight, but was easily able to book a later flight from the app while enroute.

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

The incoming plane was late and no information was shared. They even announced we would board in 10 muntes 40 minutes prior to the plane arriving, and the website said until takeoff that we had taken off an hour earlier

Boarding was excessively slow. They do it by groups in a way that it doesn’t make sense. After business class , ppl that need assistance and any other priority group they should have ppl board from the back to the front. First rows 20+. Then 15+. Then 10, etc. having ppl sitting in the back board last makes no sense. The libe backame long as soon as ppl on rows 10 or so where told to board. The line went all the way up the ramp and tunnel for 25 mins.

Seats are very tight even in Plus, no complimentary snacks or beverage

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.

There isn't much space in-between seats and even water needs to be paid for during the flight.

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.

Lounge for business was closed. Boarding was rush and stand by. Seat for business is just the middle seat blocked and some more leg room.

Flew with our two children. Paid $380 to check two bags (one was overweight). They then left the bags behind on Sunday, December 21st, with all our family’s clothes and family Christmas presents. When we arrived at our destination they told us the bags had not arrived, and they thought (but didn’t know) they were still in Boston, but that there’d be a flight the next day and the bags would arrive the next day. The next day we found out there was no flight, now we’re hoping we get our bags before we fly back out. Meanwhile, trying to get any engagement or accurate information is a waste of time. The folks at the call center are just gatekeepers, who can’t connect with any departments that actually do things to solve a problem. Getting information is made deliberately difficult. My biggest regret is that I’ve had a number of awful experiences with Avianca traveling between the US and Colombia, and still let myself get suckered into buying these tickets because the schedule was great. Never again.
