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.

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.

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.

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.

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