Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

It was terrible, if they ran flights on time it would make a big difference.

Great flight. On-time, comfortable, clean aircraft, and offered snacks pre-flight to plan for a potentially turbulent route. I wish there was Wi-Fi an all Delta Aircrafts but for a short flight this is not much of a problem.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

If I pay extra for "comfort+" I expect leg room where I can stretch my legs. I was seated with an attendant's seat blocking my feet. Knee space was fine but my feet had less room than the non-"comfort+" seats. Also, don't go cheap on food when you have flights of 3+ hours. It's insulting.

Everything was good except when we're on a 6 hour flight at dinner time and all they offer as part of the fare are little bags of junk food, it's disappointing. Bring back food service without an added price.

I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Seemed roomier than most US domestic airlines and they served food.

it was great! Boarded on-time, reasonable leg room, pleasant staff, decent food. The only thing is we were directed to Terminal 2 when the gate was actually in Terminal 1. Smooth ride. Landed early. Got off plane easily and quickly.

Very long delay but we just made the connection. The requested wheel chairs were not there so I had to assist/carry BOTH of my parents to the gate while carrying their bags so we could make the connection. The plane had no entertainment system and NO WIFI, legroom zero. Restrooms on ALL of flights were dirty and one restroom did not even work properly. I was surprised to see COPA like this since my flight with them in 2013 was incredible, the seats were amazing and the food options were spectacular. Of course, I see this kind of service on many airlines now, with services and hospitality at an all time low. The worse part of the trip was seeing my 90 year old parents go through hell on these flights and having to try and rush to a gate to make the next flight. Never again

Just a minor inconvinient with weather delay! but not Copa's fault

So many hours of flying without salty food is a shame and the fact that they want to sell it to you seems like a rip-off

This airline makes you check in in one terminal and then you have to walk to the other terminal. Its messed up

Copa crew is almost never great in terms of service.

Captain and Crew were excellent. The Boeing 737-800 was showing its age. In flight entertainment system was sluggish and my Business Class seat on the outbound flight had some mechanical issues. Only real problem was the location of the Gate in Panama PTY. It was a 40 minute hike from Security to the Gate. There should have been some sort of warning about the distance.

landed in panama it was in terminal one. We had to take a bus to terminal two for customs. Then back to terminal one. It was very frustrating. Then, on the way back from panama it was the same situation. We had to go back and forth between terminals to check in and drop our bags and then to board. When we were leaving, we had to wait in line for the boarding area and go through another gate security process. They told the bottles of water and coffee were bought while in line in the airport after we passed the main security. Ridiculous (and expensive). A much better communication system is needed.

This was my first time flying Copa but I'll definitely be back! Great service, professional agents, and delicious food for a fair price. Thanks for a great trip!

Attendants zipped through cabin so fast hardly anyone got the water they told us we could have in the short flight. Nothing else was offered.

Sucks ! All three flights I was on this trip were delayed.

The flight attendants were unhelpful. It was a packed flight, and usually a flight attendant would help find a spot in the bin for your carry on or shift things around. Neither made any effort to do so. Also, I had to then check my bag. I was told it would be on the carousel in YYZ, but it came up on the jetway. So lucky I saw others standing around for their bags. I would have walked straight past this and on to the carousel. They could have at least told me that they had given me wrong information. Very unsatisfactory.

The crew was outstanding. And the food was surprisingly good. The chicken and the pasta dish were both delicious and I was supposed with a pizza twist near Landing. We hit a lot of turbulence and the crew was calm and kind. Loved the TV in screen. Tons of new releases.

ANA was great. United was horrible. They bumped us from economy plus to economy and were supposed to contact us for a refund but no luck. We booked the seats 9 months in advance.

Smoothly flight, pleasant flight attendants. I wish there were better food choices.

Comfortable as it can be for a basic economy seat. The TV screen on my 15 hour international flight went out after 1 hour or so and it never worked again. The food is very high in processed carbs and sugary items.

A three (3) hour flight should have meal service in First Class, not just potato chips!

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

Everything was perfect except the pad at the top of the seat back. It pushes my head forward into a very uncomfortable position and it is not removable.

Just about made it for the next flight. They need to put in longer layovers if they know they close the gate 10 min before they take off. I will never do a layover for less than 90 minutes

Flight attendants on American Airlines are rude very harsh with their time of voice. Nearly identical experience as spirit airlines. However, from Spirit Airlines, you expect this level of mediocre service. You do not expect this from the big three..

Overall boarding and debarking is a joke. I dont even bring luggage anymore on trips because you can never allow them to be place then in the overhead bin or you have to pay or you check them which is even worse having to wait for your luggage on the tarmac.

It was on time, which is always a good thing. There wasn’t any food hence my okay rating.

Excellent accommodating crew at gate and on board. Baggage claim and gate checking were flawless.

Best flight by a pilot I’ve ever been on as a 62 year old

The plane had maintenance issues and didn't leave after 72 hours

The staff were very nice! However when our first flight got delayed an hour, the second connection flight was not delayed and the layover was only 40 minutes. When we rushed and made it to our gate for the connection flight, the gate said it had moved to another section of the airport. We barley made it to the connection flight, and overall we were very stressed. We asked about taking a later time for the second connection flight, but the other option was much later and we would have to wait at the airport for 9+ hours. I just wish American Airlines could have moved the second connection flight to a later time too for its customers, and thank you for taking the time to read my review.

After multiple delays (I lost count), the flight was canceled due to a "maintenance issue". So instead of a direct flight arriving at 5:00, I had to take a flight connecting through Chicago. That flight was also delayed, partially because the plane from the cancelled flight hadnt been removed from the gate and there was nowhere for the other plane to park. (Did nobody think this might be an issue during the hours after that flight was canceled?) The connecting flight out of Chicago was delayed as well. I didn't arrive until 12:30am the next morning. I should have just cancelled the trip. It wasn't worth the hassle and stress.

Perfect flight. Efficient boarding, on time take off and early arrival. Generally smooth flight.

So so, you feel like you have to pay for everything each time

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

Felt very cramped in the back of plane. There was an hour delay for take off sitting on the runway, but we did arrive on time. They charge $120 for carry on bag and backpack at the airport its ridiculous.

Same experience, very poor food, drinks or entertainment while flying. There are some products offered to buy but only using debit or credit cards . No friendly for seniors or people without cards.

Poor In food , poor in entertainment , passengers don’t get for free not even water

It’s very nice, the only thing is that we have to purchase food.

Our flight from BOS - BOG was delayed 10 hours because they were waiting for a Flight attendant to fly from Miami. They lied and said they would give us food and hotel. That was a straight Lie! It never came! We were in the airport for 13 hours with Two babies. We were on the plane 7 more Hours. When we asked to get diapers from our checked luggage, Jorge in Boston told my wife she should have planned better. Meanwhile, the 10 Avianca Employees Sat there and did nothing for 13 hours. Yes, we planned for 10 hours with the wait and the flight, not 20 hours JORGE! If this was an American company we would have got a refund! But they are not up to American standards. The kicker is they apparently needed the 3rd stewardess to serve the food. Guess what? It was 4AM when they tried to serve the FOOD! Everybody was asleep by then! Ridiculous! Never Again!

Old planes rude workers no tvs seats don’t go back and overpriced

The fees for baggage were outrageous. $130 for carry on and $150 for check in for an international flight. The seats did not recline. We were not even offered water. Had we known all of this, we would not have booked Avianca at all.

My fly was cancelled so i run to the airport and fight for my fly Thank god at the end was good
