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

I selected first class expecting excetional service. It was mediocre at best. The food service was cold, meal choices was poor and on one leg they did provide dessert. I did enjoy the lay day seat but the movies were old and nothing current. Boarding the plane is always hot. So boarding is quite warm until your in the air. I took a small personal air fan. Update the meals and movies.

Did upgrade, travel in business it was great (more room I could sleep)

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.

Seats not reclining, no vegetarian food option, no snacks. 7.5 hr flight should have been more comfortable. Luggage limits are unusually small. Will never fly Copa again and will tell friends and family to avoid this airline.

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.

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

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

This is the best united airlines flight that I took. The crew was very friendly and the food was tasty!

It is clear that someone knew, and competent, is in charge of food at United Airlines at least for the international flights. I was flying in coach, but the choices of the dinner were excellent. Tasty, and appropriate size. I had the beef, which was a little bit like a shepherds pie, and it was good. Nothing comparable has been served on a United flight in years. It will not be confused with three star food, but it is very good for airline food. Even better was the breakfast choice between a cinnamon roll and a breakfast sandwich. I chose the breakfast sandwich which was absolutely delicious and which I would happily order again at my local Starbucks or Panera. It is clear that someone knew indifferent is in charge of the food and it’s about time.

Had one staff that was not pleasant. Seems they are stressed with too many people to care for.

I would have liked an opportunity to move to a different seat ( even would have checked in my hand luggage)as I had health issues where I didn't have to clamber over the passenger next to me to for toilet use/ movement [ She was a highly unpleasant neighbor to sit next to]. In addition, I found that my European phone plan had run out of data and so I was not receiving emails from yourselves on airport wifi to be able to check in online and verifications difficult as did not accept the ticket number I had. I asked for an extra blanket but was told there was none. Then I saw other passengers receiving them. I couldn't eat the food and asked for snacks : Stewardess said " on the way" but they did not bring. The best bit was the check in process in Lisbon. Very efficient. However, I did not understand why we had to collect our bags at Washington then go through customs again. It was not explained. I also with my leg and health issue had approximately mile walk to the gate ( which then changed) . There appeared to be no moving walkways or help provided.

The attendant were friendly. I suggest you have a medical attendant on board every flight so that in case someone is sick , he/she will help them.

We had a very long diversion and our food voucher didn’t work because the restaurants were closed

United airlines, mediocre at best. No issues , nothing great . Worked for me

Turbulent taking off & landing to Dulles from Raleigh. Flight from Dulles to Tokyo very good!!

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

It was horrible. My experience with Avianca. I didn’t know it was Pakistan international Airlines but anyway, whatever it is it is bad horrible you guys need to upgrade everything in those planes. And you guys charge $130 for a carry-on did they wanna let me in with my carry-on that I travel everywhere with the luggage you guys are such a dog thank you

why did we have to go through security mid flight

The chicken that was served in business class was cold!

Flight to Bogotá delayed by 3 h Missed connection from Bogotá to Guayaquil. Avianca unable to bring us to Baltra on time Overall delay 36h. We missed boat departure from galagos. Overall 10 day trip needed to be cancelled. Avianca was completely un-professional.

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

There isn't much space in-between seats and even water needs to be paid for during the flight.
