The seats had plenty of leg room and the staff were very nice.

The seats had plenty of leg room and the staff were very nice.

Copa performed as expected for the amount of money I was willing to spend for the flight; it wasn’t exceptional but it was not bad in any way either. The crew was good; friendly and straightforward. The food was airplane food, so no expectations there and the entertainment was lacking but that was my fault for owning an IPhone with a charging port that’s not compatible with the rest of the world. I’d fly Copa again.

Left my bags in origin city on a business class ticket , spent about 2-3 days in the same clothes plus the flight .

the planes are not modern there are no phone chargers

As usual, the flight with normal legroom was not very comfortable, but the second flight was much better because we had paid for extra legroom. It was very nice to check our bags without an extra fee.

LOCKED MY BAG WITHOUT CONSENT. Had to have my zippers cut upon arrival in Costa Rica.

Pros: "The seats in economy were confortable. The best thing was Copa gave us seats in the second line and my family traveled together."
Cons: "Coffe service could better the experience"
Pros: "The crew was very interested on help and attentive with the passengers. But the seat wasn't comfortable. The design of the cushion is not the best to be seating"
Pros: "You were on time, that is the most important thing in a fly"
Cons: "You could improve your entertainment, you are not a cheap company"
Pros: "That there was seltzer"
Cons: "The management of preparing the flight and plane so that it was ready for the trip!!"

Overall fine but both ways for this trip was delayed.

I had back trouble prior to my flight and everyone was great about helping me.

My tv was broken on the flight which is disappointing when you pay for a seat and expect a service

Always delays from Boston to Salt lake but this time was very long. Don’t understand while they board the passengers and then make them sit in the plane

The boarding and flight were ok, but there were several painful issues. The flight was 3:20 in the air and almost four hours door to door, but they only had snack packs on the plane. They really need to have food on longer flights or make it clear to everyone that they won’t have food. They also advertise free WiFi, but it did not work for 90% of this flight. Again, almost four hours door to door. If I had known I was flying spirit for JetBlue prices then I would have planned differently.

Service for food to our seat was a bit slow. Snack choices were just pretzels or baked chips. My seat cushion was not attached. Other than Barbie, video choice were not very good or current.

After we landed, we were held on the plane for 30 minutes. There was no one at the gate once we landed and we forced to sit on a plan that had already over an hour delayed.

almost 4 hour delay as they over booked and had to wait for 8-10 volunteers to agree to travel next day.

Old plane. No outlets for laptop or phone. Seats worn out. Area around seat dirty.

I loved the flight and the crew. It was comfortable and smooth.

No water for a 5 hour flight entertainment not working seats with little room for knees when person in front of me reclined kept bumping my knees.

I don't think anyone actually reads these comments, so I won't spend much time on this submission. If you want to talk, you know how to reach me. The D/FW manager of Avianca (self-identified), Juan Calderon, insisted I buy an onward ticket from San Salvador even though I have diplomatic status in El Salvador and live here. It cost me $1,393 and Mr Calderon would not let me make the ticked flexible so I could get a refund. He went out of his way to be rude to me. He gave me seat 32K -- windowless window seat in the last row and did not offer to let me upgrade even though there were plenty of seats. I have flown well over a million miles in my life and this is the worst experience I have ever had. I would like a refund on the ticket I was forced to buy. Just awful!

This is the Spirit of Latino travel. And don’t even get me started on customer service.

Awful. I checked in online and there was no option to pay for baggage, at the airport when I checked in my baggage was received and Iwas not charged. When I got to LA during the boarding process I was told I didn't pay for baggage, the crew resolved I was let in the plane. When I got to my final destination my baggage was not there. It took me two days to receive my baggage. Bad service ever!

There was no food or drink service, couldn’t even get a glass of water for free. It was a long and expensive flight to not offer food or beverage on the plane.

It is better at the jfk than my home country. It was very easy and everything was on time.

There is no food. There is no in-inflight entertainment. The seats are cardboard. The airline is a living hellscape.

My experience was amazing! They helped my elderly mother board on early through a wheelchair and were accommodating to have us sit together since our seats were in different locations. When landing at the airport in GUA they were very helpful with full of hospitality.

No complimentary snacks food, beverage (not even water), pillow and blanket on a 6 hours long flight (including economy comfort). A low form of nickeling an diming. Lost a recurring passanger over a soda. Avianca never again.

Flight departure late. Got late in Colombia making us take a different flight next day. Avianca airport crew messed up my ticket so when a I got in Brazil I didn’t have a ticket for my destination. Had to buy a new ticket out of my pocket.

Paid for premium economy had no tv the whole time the crew tried to reset/reboot but would not work they said they would put a trouble ticket in for it. We had 3 seats my tv was the only one that didn't work. They cancelled our flight re worked us on another that left us at airport over night on the floor I have a ten year old and a 78 diabetic mother which also had shingles and suffers from nerve pain in legs and back. Requested wheelchair service at all airports after the re route NO wheelchair service was there to help. WORST experience we have ever had. Went to American airlines assistance it was closed. I AM FURIOUS!!! I expect some sort of compensation from this traumatic experience and no need for flying points we don't plan on using American airlines again!!!!

This is by far the worst experience I have had with American Airlines. The start of this trip was a complete disaster. I purposely planned my trip so that I would weather any delays so that I could make very important meeting at the Pentagon. My flight was cancelled because of maintenance and I was put on the first flight the next day but I was late to the meeting. After a long week at the Pentagon I just wanted to go home and my flight home which was early in the day was delayed. Eventually the flight was delayed until the next day. I was not authorized a hotel room because DCA was my point of origin. So I paid for a hotel out of pocket. The flight this morning was boarded then deplaned because the aircraft was hot. The flow of information was not happening in DCA and made it worse when the news was bad. I am going to take a break from American for my next few military flights. Hopefully whatever has been going on with American Airlines will be resolved.

We had a 2 hour delay. The seats were smaller than most other airlines. The person in front of us wanted to lay back and we had to stop her because she was pressing against my girlfriend’s legs. We had to ask her to sit up and not lay back due to the lack of room.

Information when booking said the flight would be with American Airlines but the flight was actualy with British Airways. Check in from Orlando was nice and quick. I agreed to put my cabin case in the checked luggage as it was a full flight. Case came back damaged (unable to put the handle down) so will have to dispose of it. Seats were quite cramped with very little leg room, even for economy. This was the experience of both the outgoing and return flight. Cabin crew were ok and flight time was punctual.

Everything was fine once we actually got on our flight. It was more then annoying they canceled (delayed) our flight. We lost out on a day of our trip along with money on our stay. Plus we had to book another hotel. So expensive.

This flight was canceled and delayed several times without explanation. The plane was freezing cold and no wifi for messaging. Getting off the plane was terribly unorganized and felt like it took forever….

The flight was delayed several times without explanation. The seats were terribly uncomfortable and wifi isn’t included. All these make for a less than ideal flight.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

Internet service was erratic. Crew service was poor and slow. My luggage on this non-stop flight was lost and not recovered

Terrible. I didn’t fly and I had an important meeting the next day.

Flight was canceled less than 6 hours before takeoff, rebooked on a flight that was twice as long and left earlier so we couldn’t make it, when using text support option took over 2 hours to speak with someone.

Not enough help at airport during boarding process. Flight was delayed. Overall WORST flying experience I’ve ever had. Will NEVER FLT SPIRIT AGAIN

Terrible legroom, seats do not recline, tray table the size of an iPhone, delayed flight, have to pay 5$ to get a cup of water onboard.

Could have TV/Movie and some water ou soda free

Flight was good and clean but delayed over an hour on the return flight.

The non stop flight and able to go into Atlantic City airport. They could lower the prices. It starts out low but then if you want to bring luggage and pick your seat the price goes up quite a bit.

Flight got diwngraded last minute and left us stranded. I was told I’ll be given credit for my luggage and seat upgrades but haven’t got anything yet

We can’t predict circumstances like this ahead of time, but I give your staff a hats off for immediately giving us updated informations.

It was nice! There was a very unhappy child in front of us and the flight attendant did a great job calming the child. I was impressed.

The plane was not on time for boarding or departure or arrivals.
