Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

Every flight was delayed except the last one. One layover turned into two. Travel time extended by three hours. No compensation offered. Repeatedly asked if I'd like to cancel my flight for a partial refund.

It was a pleasant surprise to have complimentary Wi-Fi on the flight

Much better than Latam, the worse airline company ever. I hope I don't have the need to fly Latam ever in my life again.

Everything could and should be better. We are paying for, it's not a favor, it's a service and should involve quality, responsibility and respect.

Seats were comfortable, 8 hours. One flight attendant was not appropriate in his verbal response: "Please, DON'T touch me.", after being tapped near his elbow after being made unaware he skipped serving me & had passed further down the aisle.

Boarding in Amsterdam is always chaotic. More complicated than needs to be ( boarding pass checked twice, once for general security, then by the airline). The bathrooms on this flight are dirty, and smelly. The food was mediocre at best The crew was decent

Seats in Delta Main are unbelievably close to the seat in front of. Hard to get a backpack under the seat.

Round trip flight to Canada and back to the US was smooth and efficient.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

Boarding was a mess, they call all priority members without distinction so gold, platinum, silver were all mixed together in a long line which defeats the purpose

Boarding was confusing from staff telling going to preboard and than to group 1 Airplane was not cooling at the beginning

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

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

Copa staff at PTY and one particular crew member were unhelpful & rude.

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

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

I liked the meatloaf the chicken was awful but the plane was on time and got there and the staff was nice.

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.

It was good overall except from Omaha to Denver when flight a was a repeatedly delayed apparently due to some issue at Denver. Communications could have been handled better. I had to board then deboard with luggage and board again

Left an hour and a half after the listed time. Up side was it had TV screens on the seat.

No screens or meal options. Freezing cold. Dirty seats. Left late.

O’hsre taxi and deboarding took 40 minutes. Needed 20 minutes extra time between connecting flights to avoid running through terminal.

Seats very comfortable; service efficient and pleasant; flight was on-time; boarding organized.

Seats were not super comfortable and food was not good at all. If I had a chance I would definitely fly a different airline. Of course they are better than any budget airline, but not by much.

Overall a good experience, but no wifi available for free or for purchase and we got wet from condensation or other water source during descent.

Very friendly and helpful staff on board and United was excellent when I missed my onward flight due to the delay in London. Very well organised meant much less stress

Flew steerage class. Short on leg room unless you pay more. No window unless you pay more. Etc. United is trying to squeeze every cent from you. It doesn’t make for any loyalty.

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

The passenger in front of of me reclined their seat back all the way the entire flight. Their headrest was in my face the entire flight! I barely had room for the little plastic cup of water to fit on my tray table; can you make the seats and space between the rows any smaller??? You can’t even get up to use the restroom! Worst flight I’ve had in a very long time!

We had several flights and they were all on-time and flawless

My Frequent Flyer nber wasn't put on as I was told it was..... This resulted in a last group boarding and no priority tags on My bags.

Terrible steward... Plane was quite empty... I asked to move "back" in the plane and the steward said no... Unnecessary power trip of mediocre people.

The small flights with Valet Luggage has a poor service

not sure why you ask about food, I n3ver get food on flights except maybe cookies or pretzels. wifi was slow and in and out most of the flight not good.

Everything was fine except the end of the flight. We spent more than an hour circling around Miami due to weather conditions. That was not good.

They lost my bag. ... And I asked them 3 times to 3 different people if my checked bag will maKe it all the way - they all confirmed and at the end it was left at the connection... Bravo

Cancelled BOYH legs of our flight home 30 min before initial boarding

Cancelled the flight half hour before boarding. Then cancelled the connecting flight too.

The airline did not allow enough time for the Columbia checkpoint

This was my first time flying with you guys and my very last! This was the most horrible experience!!! There was not even tv in the plane! How cheap can this airline be!!! I paid so much for my suitcase!!! I would never fly with this airline again! The crew are very rude!

The crew was great! They waited for me as Air Canada flight was delayed by 1:15 hours from Ottawa to Toronto. I am a bit disappointed that we could only use wifi for entertainment but I survived! The only thing I would of liked is a more comfortable seat. The seat cushions are not thick enough for flights longer than 3 hours. Aside from that, everything was great.

The worst experience I've ever had because the "people" @ Avianca wouldn't let me fly because they said I needed a round trip ticket

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.

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

Not even water is offered on the flight. You cannot lean back on the seats and the seats are so narrow you can’t avoid rubbing elbows with the person next to you.

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
