There should be a warning regarding the quality of the aircraft on the website as we reserve the tickets. There was no TV or any type of screen onboard. The wifi they offer is good for nothing. Traveling 9 hours straight with kids and no type of entetainment was horrible. I wish I had been informed prior so I could buy a ticket with another airline. The food was a joke too. A very tiny portion per passenger. They also charged $100 per checked bag. With United I used to pay $60. So, fair to say that I wont be flying Copa anymore. Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.

Very strict carry on rules meant most of the plane had to gate check their luggage. As is often the case had things that were broken because of this, but I appreciated not being charged to gate check. Otherwise good flight and great crew once on the plane

I liked the meatloaf the chicken was awful but the plane was on time and got there and the staff was nice.

Boarding was quick & efficient; they gave boarding groups due priority; staff & air crew were very cordial and helpful, pleasant flight.

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

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

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.

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.

Boarding groups were called up in Spanish only. Luckily I know some of the language. They gave out grilled cheese sandwiches and a cup of fruit. I was very disappointed. I could only eat the cup of fruit because the only other option was vanilla pudding. The entertainment system and seating were great though.

This airline always trick us so we end up paying again for the luggage’s. This airline is worthless and take advantage of travelers .

Now days most airlines flying to Central America have a really poor service, but if you buy first class they will treat you better. I miss those days when flying was fun.

Friendly staff at all very easy check in and organize process

Horrible airline, upgraded to sit on seats made of stone. Staff were rude and on top of it they charge an arm and a leg for luggage 🧳 never again

The seats are the worst I upgraded to premium big mistake and it seems like no one likes there job very unpleasant

they don’t have TV Seat to Type in space

Staff could’ve been a little more cordial. The men were much more friendlier than the women. My daughter and I also missed the 2nd to last meal as we were sleeping but that is on us.

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

Our flight was canceled same day and we were never informed. Had to pay more and worse seating on another airline.

Did not like that we couldn't complete check in on-line without providing pictures of our passports. Worry about identity theft. We had no delays and boarding was handled In an efficient manner.

Excellent! I got to Munich and was transferred to my Lufthansa flight quickly, in 15 to 20 minutes, so I did not miss my flight. However, I had checked my overhead bag at the boarding gate in Tampa. That got to Tunis the next day. That is to be expected.

WiFi didn’t exist , seats were super cramped, lights stayed on near my seat for a long time while others were dimmed, the food/trash/drink cart hit my shoulder at least a couple of times while moving, food options were down to just one option by the time it got to my row, the utensils were garbage (knife bent at a couple of places by the time I was done eating) the spoon was very flimsy plastic

Vegetarian selection could be better. Bread was too hard to chew.

Crew was friendly and competent. Food, wine, and entertainment were excellent except the raw tuna on the flight to Split. Recommend against serving that - at least as the only option. Many medical conditions do not allow people to eat raw fish.

After arriving in Chicago, we were taxiing for 1.5 hours with infrequent and untruthful updates about the amount of time it would take to arrive at the gate. Minimally, the team could have provided timing expectations that were more truthful, especially one their original expectations were not met.

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

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

Did not fly with Pakistan International Airlines. Have never flown with Pakistan International Airlines.

Boarding, crew were excellent, food was ok and entertainment need to improve

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

We were not aware carry-on bags cost extra until we arrived at the airport so, we were charged $240.00 for two small carry- on bags! There was a substantial fee for drinks and snacks. No wifi, or other entertainment was available. Waiting areas were crowded and uncomfortable.

Ok, but these people don’t give you nothing no snack no water

No water for a 5 hour flight entertainment not working seats with little room for knees when person in front of me reclined kept bumping my knees.

I don't think anyone actually reads these comments, so I won't spend much time on this submission. If you want to talk, you know how to reach me. The D/FW manager of Avianca (self-identified), Juan Calderon, insisted I buy an onward ticket from San Salvador even though I have diplomatic status in El Salvador and live here. It cost me $1,393 and Mr Calderon would not let me make the ticked flexible so I could get a refund. He went out of his way to be rude to me. He gave me seat 32K -- windowless window seat in the last row and did not offer to let me upgrade even though there were plenty of seats. I have flown well over a million miles in my life and this is the worst experience I have ever had. I would like a refund on the ticket I was forced to buy. Just awful!

There was no food or drink service, couldn’t even get a glass of water for free. It was a long and expensive flight to not offer food or beverage on the plane.

It was awful everything about it terrible I will never ever ever ride it again

It was awful ....my first time flying on it and I will NEVER fly it again ....everything about it was terrible .....most especially the flight attendants

More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!

Frontier Airlines was AWFUL. I was an hour early for my flight and the lady refused to check me in. I had to purchase a whole new ticket with a different airline.

I missed a flight because of a delay. I had to buy a new ticket through Southwest.

Bag should not be so much money. This is how Frontier takes advantage of customers

Frontier is definitely a good option for people traveling light or on a budget - just remember to bring your own entertainment and your own headphones if you need them.

Never offer anything to drink ☹️ Flight delayed gate moved poor communication

It’s a cheap airline. I wish they had better seats.

Seats are cramped and very uncomfortable. You have to pay for everything and it is too expensive.
