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

Flight got delayed; had to go through security three times.

A lot things happened in this trip.The fly should be less stress.

Horrible. No TV or any type of entertainment on board. Passwnger listening to/watching stuff on their own phone with no headphones making it noise and uncomfortable for everyone else, little/tiny food portions, old seats, useless wifi (cant access anything). Horrible exlerience especially it was a lomg distance flight with kids.

There should be a warning regarding the quality of the aircraft on the website as we reserve the tickets. There was no TV or any type of screen onboard. The wifi they offer is good for nothing. Traveling 9 hours straight with kids and no type of entetainment was horrible. I wish I had been informed prior so I could buy a ticket with another airline. The food was a joke too. A very tiny portion per passenger. They also charged $100 per checked bag. With United I used to pay $60. So, fair to say that I wont be flying Copa anymore. Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.

The flight was good overall. Everything went smoothly, although the landing was a bit rough. Still, it was a pleasant experience

I always enjoy flying Copa. There are very few airlines where I can enjoy a comfortable sleep in-flight. The snacks weren't the best, but they sufficed. The in-flight entertainment was fantastic, and I crossed another movie off my watch list.

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

Simply as follows:- First, there was no vegetarian option for the meal Second, only 2 washrooms for the entire economy class.

We had a great flight just wished they had a tv so we can see a movie that would of made my trip excellent.

Would've been great if Lufthansa union cockpit pilots didn't strike for 2 days and caused a chaos to my returning plans to USA, and then after rebooking a flight 2 days later tge plane departed 35 min later. So I did not have a good experience.

Everything was on time and service on the flight was great!

The boarding in Buenos Aires (at the on ramp) was not great. They had to check every carry on. Not a United problem but was a Buenos Aires problem.

Staff and aircraft were good. However, weather in Houston lee to a ground stop. We were looking at circling behind three other planes until the stop was lifted. Pilot said we didn’t have enough fuel for that. So we flew on to New Orleans as the closest port with immigration and customs staff. Landed there and sat in the plane for two hours plus while staff was sorted. Turned away by ICE. Waited for pilots to be switched out, but after they were approved by ICE. Then had to wait to get a runway because so many planes were ahead of us. Finally took off and flew back to Houston. We all missed our connecting flights because it took too long. Hotel voucher from United was only a link to booking site. Total BS. Finally got a flight out the next day after a night without sleep because all the Houston hotels were booked by rodeo and spring break crowds.

Wifi Bluetooth features for watching in flight movie was horrible. Screen kept blacking out no connection of sound although it said connected. Other than that smooth trip .

I paid $7,000 to fly round trip to Porto. I thought it was for business class. But on the leg from Miami to Newark, and again from Newark to Miami, i was in coach. One time in the middle seat of coach. From Newark to Porto I was in business class as expected, and it was fine. I fly to Portugal once per month, often paying $5,000 for business class. Usually i fly American Airlines. I'd be happy to fly more with United Airlines. But my experience was disappointing because i was put in the coach for almost half the flights.

The travel company that you have on your site did me so wrong. I don’t know how it happened, but they put my son‘s name on my plane ticket flying to Vietnam. Along with his birthday. They would not have let me fly from Fort Myers to Ho Chi Minh City. I don’t think that I can ever use your service again. I typed my information into the browser along with my passport number and four days before I’m leaving I have to quickly search another ticket to fly out here.

Seats are uncomfortable. This has been a trend in the industry for decades. Trying to fit more seats on each plane to increase profits at the expense of the passenger.

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

It was okay, the food was good, but after the landing there was not enough time for luggage and security to catch a connection. It was crowded on board.

After changing the departure gate 5 times making us mo e from one side of the airport to the other and then back the flight was delayed nearly 2 hours. The male flight attendant had a bad attitude with the guest being condescending, disrespectful with people who were already on edge.

Easy boarding. Rows are smaller but that may be an older and bigger me now :)

It would have been nice if American tried to care.

American Airlines did everything they could with the high Spring Break crowd. I was frustrated to be changed from 1st class to a middle seat at the back of the plane. This has happened before, not sure booking 1st class and paying the extra actually works.

I booked 1st class, my flights were changed and I was sitting in the middle at the back of the plane. A far cry from the 1st class I purchased for my flights. I am grateful I arrived on time.

Movie selections were very limited. Meals were not f So good.

Older airplane with worn out seats. No entertainment system at all. Connecting to Wi-Fi was problematic and hit and miss.

AA is flying sub par aging 787's to Tokyo. I fly other 787's long haul and these are at the bottom. Seats don't work well, tray tables don't work well and were dirty. The flight was great, the plane was not.

There was no beverage service and the only time I saw a crew member walk through the cabin is when we were preparing to land.

Our flight was delayed 3 times and this is why I am giving such low reviews. Everything else was okay but being in the airport at 4:30pm for my initial flight at 7pm to not leave until after 9:30pm is insane,

I had bad experiences before now was excellent I am glad they have business class again

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.

It was delayed and I lost my connection flight to Cali and I missed my Mom's funeral and avianca lost my check in luggage

We found the chairs to be really uncomfortable. It’s also really unacceptable that no form of food or drink is included in a 6+ hour flight

The flight attendant smashed her beverage cart into my knee, causing significant amount of pain. The seats were extremely uncomfortable. No food or drink is offered unless you want to pay the ridiculous prices for it. The schedule of flying in the overnight hours is also very uncomfortable.

Last seat of Bussines Class it does recline but passenger seating behind kept pushing since they did not have space once my seat was reclined

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

This low cost airline looks and fells more like a local bus. In a 6 hour flight not being able to recline a seat is torture. The only thing available with no charge is a glass of water provided by, mostly, rude staff. Our luggage didn’t arrive

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

The plane was clean and crew was nice. Can’t speak on food as I did not have any

Flight was delayed, then undelayed, then delayed again. Gate was changed to the other side of the airport. Horrible seats with no screens. Spirit os truly awful, even for a budget option.

Flight was cancelled without explanation or option for same day or next day flight

flight delayed because of poor staffing and organization - confusion from gate agents and flight attendant supervisors scheduling a missing flight attendant. flight delay 1 hr 30 min

I liked the quickness of the boarding process. Things were run smoothly and the staff was very professional. The overall experience was great.

Flight was delayed more than 3 hours, and the metro had stopped running by the time we got to the terminal well past midnight, so I was stranded, alone, with no way to get home until the metro started up the next morning.

We get stuck in the plane when landed during 45min and no communication from the crew People were listening to their phone and music out loud and nobody told them anything I definitely want stop booking spirit flight it is a disaster

When I arrived at the airport at 4:00 in the morning, I was notified that I "hadn't paid" for my ticket (I had paid and had a boarding pass). Then I was told that while I had paid, the ticket was $600 more than it actually was, and that I needed to pay that so I could board. None of this was true, of course, but it took 20 minutes, two crew members behind the desk, and one on the phone to clear up.

The flight was delayed by two hours, then by three hours. Then, at 10:01, a notification that the flight was back on schedule for the original time. I just happened to be getting on a train to go to the airport at 10 just to be extra early for the delayed departure when I saw the update come through. I got to the train terminal at the airport at 11:07. A shuttle immediately arrived and offloaded, but didn't show anyone on before speeding off. It was 30 minutes before another arrived. I finally got to the terminal and through security and to the gate just in time for them to tell me the door had just been locked. Flight closed. I had to wait until the next day to fly out. No or for a hotel, a meal, nothing.

Good: It was cheap and they got us to our destination safely. Not so Good: Gates experience with many, many nauseatingly (almost) threatening announcements about bags size and how much they were going to charge us if our bag was too big, even to the point of having a gate agent roaming around through the passengers eyeballing bags size and making people go check their bags in the sizers.
