Chaotic boarding at these gates, multiple gates squeezed in at the very end of a concourse, behind a restaurant. Agents gave up on boarding by individual zones. Flight itself was uneventful, which is all we hope for any more.

Chaotic boarding at these gates, multiple gates squeezed in at the very end of a concourse, behind a restaurant. Agents gave up on boarding by individual zones. Flight itself was uneventful, which is all we hope for any more.

Flight delayed due to ground hold. Republic airways did a great job.

The flight was smooth, the crew was great but the plane was quite old

I lost my plane and spend 5 hours at the airport arriving at Buffalo at 1 am taxis are very expensive at that time.

Flight was warm for first few hours and quite rough

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.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

Excellent flight from boarding to landing. Plane crew was informative, warm & attentive.

1st flight had mechanical issues after we boarded and almost took off. They tried to fix on runway but couldn’t do we went back to the gate. They couldn’t fix it there either. So we had to deplane and board another plane 2 hrs later. All in all our flight was delayed 4 hrs so we had to cancel some business meeting we had in London for the morning since we were supposed to arrive at 7am and did not arrive until 11:45am. Also, the 2nd plane had mechanical issues as well but fortunately they were able to fix on runway.

I am surprised that a company of such prestige would let you board a plane without air conditioning and no WiFi, not to mention that we had a delay of just over fifteen minutes and many passengers arrived...It was a flight beyond Delta's prestige.

stood in line to check in luggage for nearly an hour. very poor service and not excusable

Same as the previous flight as far as comfort and food. Entertainment didn’t have a watchable screen so everything would need to be watched on your own device in which they didn’t have a charging port that accommodated my iPhone. Seats were very uncomfortable. Staff was very friendly.

Do not book it’s a scam! They stole $1200 from me

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

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

Great experience with a crew always thinking in the passenger

We paid extra with copa for seats near one another The plane was changed and we lost our seats We were all Separated. We have not received a refund for our seats despite emailing and calling.

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

Copa crew is almost never great in terms of service.

In flight from Miami to Anchorage, we were all on board ready to take off. Pilot decided to take on more fuel causing a delay. Once fueled, the pilot came back over the radio stating more delay due to VIP. These delays caused me to miss my connecting flight. I went to the Alaska Air counter for information. They flat out stated that it was ATCs fault that I missed my flight and booked me a flight the next day about 1300 . I believe if we had the fuel prior to getting on board we would not of been delayed and I would have taken off on time. Pilot was taken out of the equation. I think they should’ve taken responsibility for their pilots decision to top off his aircraft instead of waiting til the last moment. Enough said…

We liked the way we were treated by the sraff at lima airport counter and the the flight attendants. We did not like the fact that the kiosks at airport rebooted after we entered our information and then told us that there was an issueand we needed to go to the counter. Such a waste of time for a group of 6. Once we got our boarding passes there was no assigned gate so we did not know where to go.

Nothing I like, I missed this connection b/c of an earlier flight delay. I had to stay one more night and I paid out my own pocket. LATAM failed to send me to a safe and decent hotel.

It was delayed for 2 hours. Then when we arrived they took us on a very uncomfortable bus and left us there. The bus driver wouldn't let us out because no one from Latam was there. Everything was disaster.

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

It’s a delta flight operated by LATAM. The whole ticket sale is a mess, delta changed my flight but didn’t update it in LATAM system, I couldn’t get my boarding pass, it took me hours to resolve this issue with delta. I had to change my travel plan. No apology from Delta even though it’s their fault.

entertainment was not good; the shoulder strap on Business class seat did not sit well across the body (more like across the neck); the food was not hot and the special meal promoted by insert in the menu was not available to us

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.

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

Better seats, allow us to upgrade, terrible website, poor telephone service, better equipment

Horrible experience with Avianca, they delayed their flight and when we arrived to NYC, AVIANCA took 1 hr y 30 mins to park the airplane and all passenger get off the plane, it made me lost all my trains to get back home and I came back to my place at 3 am instead of 12 am. On the top of that their plane seat are so uncomfortable and is not enough space and killed my legs and knees, Avianca used to be good when it was a Colombian company, now after Brasilian company bought them, their service quality is bad and their flights are delayed and oversold.

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

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

The check in is the only positive thing in Avianca. The seat is the most uncomfortable I have traveled, the distance is minimal.

Not what it used to be. The sale of food makes them look greedy!

Avianca is not what it used to be. So disappointing

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.
