This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

This flight was a first class choice and left much to be desired. Seat backs on seats were falling apart and torn. Seats actually didn't come to a "full & upright position". Pull out table was sprung. Not any significant leg room. All in all we were on an obviously older plane and felt overcharged for what we received as first class.

Flight was delayed several times. At one point, they "pulled back" 15 minutes from the delayed boarding and sent a text saying we would board sooner than previously advised. The flight then was delayed again. And when we boarded, there was an unspecified technical issue which had us waiting in the plane for about an hour.

Delta is a good airline. I've never had an issue with Delta. I'll continue to fly with them until they show me that I shouldn't.

The only thing nice I can say is the flight crew was really nice and apologetic about the situation. They shared as much information as they had and advised us on what we could do about missing connecting flights. The boarding process was so slow. The gate agent was working by herself and should have had someone working with her. It took almost an hour to board because she was trying to board a full flight of people and provide customer service to everyone who was flying standby and/or had questions. It was really chaotic. This didn't help the fact that we were delayed and folks were missing connections the longer it took.

The gate attendants and the crew were terrible. Because of high winds, they needed to carry more fuel, so they had to get volunteers to take the next flight at 6 am the next day. They did a terrible job of it - our flight ended up taking off just under 3 hours of the scheduled time. I hope to never fly Delta again.

Did not realize internet screen was hidden between seats and no info printed!!!!

I went to washroom twice and once there was no toilet seat cover and the other no toilet paper at all. I don't think it was ever replenished or checked before we boarded as it was very early on in the flight.

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Very good flight crew and very nice people staff were incredible especially the gate agent

I always enjoy flying Copa. There are very few airlines where I can enjoy a comfortable sleep in-flight. The snacks weren't the best, but they sufficed. The in-flight entertainment was fantastic, and I crossed another movie off my watch list.

Some of the Air hostesses are not that friendly. Need improvement

They were super friendly bumped me up to exit row free of charge, All flight legs were on time

As always, Copa Airlines is great to fly on. The flights are always on time, the staff are pleasant and helpful and it's always a wonderful flying experience.

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

horrible service, food was an embarrassment, no charging for cellphones, stay away

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

Great experience with a crew always thinking in the passenger

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

Had to go through security at the gate again. Had to take off shoes and go through the whole thing again even though we have global entry. They asked us to check in items bought at duty free during our layover and since we checked our luggage at the original departure airport, they forced us to check in a small backpack. None of this ever happened with other airlines. In addition, no vegetarian food option and no snacks during a 7 hr flight. Luggage limits are unusually small. This is unacceptable. Will NEVER fly Copa again and will tell friends and family to avoid this airline.

I booked a flight through Kayak to Brazil I have traveled to Brazil several times before Kayak Delta or LATAM never mentioned during the booking or in the pre flight process that the visa requirements to visit Brazil have changed earlier this year. I was unaware of this change and as such never got a visa and was unable to fly from JFK to Sao Paulo Add to this that Delta allowed me to fly from Boston to JFK which they should not have as I didn’t have a visa. It has been a terrible experience and a huge loss of money

Wish the seats were a little more comfortable.. it was a 6 hrs nonstop trip. But the crew was courteous and w a smile

I like this airline a lot no problems at all, except being forced to check a carry-on bag ., Overall very good airline

The assistance we received and the flight itself was wonderful. We will fly with LATAM airlines again, in the future.

Poor, the airline was not able to help me move flights.

we were missing our luggage, trying to find someone to have any empathy was pretty much not happening....

The plane broke down at the Lima stopover and they offered to put me on a flight the be t day but I had to be back in LA that morning and so I had to buy another ticket from Avianca and United for $2k I asked LATAM for compensation and received none. Very bad experience

The flight was late. Please do not delay next time.

I couldn't travel, now I can't get a refund and to change the date I have to pay an absurd fine.

I never got this flight. You sent me to Chile!!! And from Chile I got the other flight to São Paulo... I've arrived 7h latter than I was supposed to arrive because of Delta delays.

The flight was delayed for 1:30 hours for maintenance issues. They should give more information about connecting flights. For a Business Cabin the Crew was mediocre.

The food is terrible. The same pasta or chicken with bad taste and presentation

It was probably one of the worst flights I’ve been on. The restrooms were never cleaned or stocked. The food was very subpar, and i usually enjoy airline food, so I was disappointed. It was just all around a bad experience. The only saving grace was the flight attendants.

The only downside was my cell phone charger wouldn’t work in the charging port but everyone else’s would work in them all. My cell phone cable works fine in my hotel room in Frankfurt.

Great crew, excellent landing, good food. Over all great experience. Thank you!

One bag is incorrect and not acceptable for an international flight. The food was not just good. I won't fly with them again.

Not pleasant trip cross country when the entertainment and WiFi system not working. No entertainment for entirety of route. Staff was rather nonchalant in that they dismissed the problem due to age of plane. It would have been nice to know this up front so I could have come prepared to read or download movies before boarding Coincidentally or not, there was a similar issue with the entertainment system on my previous flight I took on my fist leg of the trip. There are no seat TVs, so you must rely on the app when it works. United can do better. Also, what use it it to pay for boarding group 2 when half of the passengers are in the same line as you?

Crew was dismissive. Snacks and refills not offered. Poor business class experience. Bed not comfortable compared to Emirates or BA.

Flight was delayed for 5 hours because crew didn’t have enough time to rest - this seems like it could have been avoided with better scheduling. Food was not good.

IAD with the archaic people movers is just a place to be avoided.

Avianca has transitioned from full service legacy airline to "low cost" but has now became a strange hybrid (minimum leg space, started offering business class in domestic flights again, charges passenger for printing boarding pass, etc.). National and international coverage and destinations are really wide but service is not at its best

We found the chairs to be really uncomfortable. It’s also really unacceptable that no form of food or drink is included in a 6+ hour flight

Boarding was late due to the company’s that cleaned the aircraft (very poorly done) and the catering company. The entertainment system was not working for this six hour flight, uncomfortable seats in business (barely any cushion or recline). The airline staff is very good but the planes are horrible and not well maintained.

Deplaning was a mess, I sat in business (seats are horrible) and the front door had a problem so we had to deplane from the rear exit. The stairs were not tall enough to reach so there was a large step down from the plane to the top of the stairs.

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

Here we have another airline flying to Guatemala but doesn't have a plus or a less, just in the middle. Why? Well, first we don't have even free water Movie selection is poor Seats don't recline in some places Food selection is carb based Forgot to mention, customer service on the web is the worst. Good things; Very reliable on schedule Kind crew

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

No free snacks nor drinks on very short 30min flight. Entertainment system is over wifi to your own phone or tablet, which is good but often a show or movie just stops and refuses to continue

6 hour flight and have to pay for everything 100 dollars to add a carry-on bag is insane
