I like for how they process during check in. It was very smoothly.

I like for how they process during check in. It was very smoothly.

The flight was scheduled for 2:30 PM. Early in the morning we got a text message saying the flight was delayed and rescheduled for 3:00 PM. We got to the airport with that in mind. Then we got a message during check-in at the flight was rescheduled again for 2:30 PM. We almost missed our flight. In fact, our bags Were told that they would not make it. At the end, everything worked out. But it is very stressful.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Excellent check-in. Crew was good. Excellent communication from flight deck.

Great overall. There was a bit of turbulence so they could only serve water because too much turbulence for the carts. Was glad they prioritized safety though

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗

5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

I travel often with LATAM, it never disappoints me. The service is great, nice crew, latest and some classic movies. I got 3 small meals, cannot complaint. I’ll definitely travel again with them.

It was good, however the airplane was really cold. We received snacks and the crew was friendly.

Delta has an outstanding service. They are courteous and punctual most of the time. The flight departed a half hour late but we arrived 15 minutes early.

Not sure why there are so many security checks at this airport. Consistently annoying showing passport over and over, checking carryons at gate all the while trying to make tight connection. Basically it was uncomfortable crowded cabin with meidiocre service

Change of gate in Santiago devolved into half plus hour delay and a really tight connection in Lima

Although the flight is goof and the crew is good, the way the airline charges you for every service is ridiculous.

Plane never left the ground. Mech issues - entire trip was rerouted through united.

They didi not provide wheelchair though we had requested. We had to run around for 40 minutes and arrange it from the airport!

Everything was good except the check in. Could not do it online neither on the machines in the airport. Needed special assistance from the airline desk clerk

No entertainment but not expected. Unless you are referring to monitor that you can use. Then Al, was fine on all flights.

It was ok. However, the food was quite poor since I don't eat pasta.

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.

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.

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

We were in transit from Lima (flight at 1.10am) and we were in stand by in our flight from Panama to Washington. We wait from 4.30 am to 18.30pm in the Airport. The company give us 2 x 15 dollars for eat during the day and a personnal travel voucher of 400 dollars each. Do they buy food one time something in the Airport ??? And one of us live in France so the voucher is not usable. More than 24 hours travel !! And our place were near the toilets, with 8 children around us. The boy behind my seat stamped his feet on my back all the flight. Really Wonder full ! So we are totally unhappy with our travel. Thanks Copa Airlines....

I upgraded myself to Business Class at the last minute so I had a DREAMS window seat. Seeing as I've never flown Business before everything was novel and fun for me and it made the 7 hour flight much more enjoyable for sure.

Great from check in all the way to the end. Very happy with Copa

I loved my experience. Very safe, Very informative and very friendly.

At JFK the Security line was extremely long and few checkpoints open.

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

Late departure. When the flight arrived in Medellin the plane sat at the gate for 20 minutes waiting for a bus for us to get off the plane.

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

A few years ago long flights 6 hours or so used to have video screens and they offered ear phones. The food cart used to come and drinks. Now absolutely nothing. Avianca is as bad as Spirit Airlines. Avianca will now be my last choice when booking my next flight.

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

Purchased a business class ticket and got a economy seat with center seat blocked they call it business. 3100usd ticket on a flight where economy costs 500usd The biggest scam insult have had on a regular airline. Avianca should be in the low cost category and kicked out of Star Alliance. I want the difference to be credited. Ets see what Avianca does. No reply so far. Avianca = low cost airline. Beware

COP 7,000 for a cup of mediocre coffee. I thought I was on Spirit Airlines for a minute. Otherwise the flight was fine. Nothing exceptional to report.

I paid over $200 for seat selection for these flights and I was still stuck on long international flights in seats that do not recline and do not have the head support cushion. At this point basically all airlines have those for all seats, and this really took me by surprise and made me not ever want to travel on Avianca. The Kayak agent who called me for the seat selection (Donovan) was courteous, but it seems the system for this doesn't work. I was offered seat selection, for the $200+, but without being able to see what I was selecting, with no guarantee where I'd be...and then I still ended up in terrible seats. On my way to, and especially after, a very intense business trip, the seat situation really soured my experience.

Overpriced checked bag price of $120 and they charge you for carryon if the size is not minimal of $120.

They charged me $120 to check one bag and then charged me another $120 for a carryon. Ridiculous!
