Horrible exlerience especially it was a lomg distance flight with kids.

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.

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

They were super friendly bumped me up to exit row free of charge, All flight legs were on time

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.

Cops Airlines is fantastic! The level of care and professionalism provided by the entire crew was top rate.

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

Great experience with a crew always thinking in the passenger

The flighr attandants were very rude they ignored me didnt offer me anything to drink throughoit the 4 hour flight i feel i was targeted and ignored because i was a darkskin latino man.

Very happy with my flight. I would definitely recommend it.

The professionals have excellent customer service, the seats don´t have enough space.

The flight was very smooth and the meal in business class was great.

We had 3 flights. 1 & 2 were on the same plane but we had to de-board just to re-board 30 mins later. That may have been due to a crew change though. Our 3rd flight had a couple “maintenance” issues that held us up. They were quickly resolved but it took forever for someone to bring the paperwork needed so we could leave. Apparently there was a computer glitch so a driver had to bring a physical copy. It delayed us about 1 1/2 hrs. The flights themselves were smooth & no problems. For boarding, I don’t know why they don’t start with the back of the plane & move forward. It would eliminate the back up from people trying to find their seats & put their bags in the overhead bins. Unless you’re on an overseas flight, there is no food, you get a beverage & either a small bag of pretzels or a biscuit cookie. Take your own food or snacks of you want something more.

Full flight so overhead bin space ran out & bags had to be checked. When you’re in the last boarding group, you might as well expect that. Don’t pay to check bags though because when they run out of space for carry-ons, they check your bag to your destination for free. When traveling with children, no need to pay extra for seats, they will assign seats & have to sit your children with you.

Flight was delayed again and again ultimately almost three hours getting us to our location at close to midnight by the time we got in and out of airport to destination. I had taken time off work to enjoy an evening at destination and that was now wasted

Boarding was very efficient. Everyone got on board and we got on our way very quickly. It was frustrating that the entertainment app was not functioning properly. I was not able to activate some of the movies offered. The crew on this flight appears to be pretty grumpy. They had no smile on their faces. I felt like they were doing us a favor for being there.

Everyone was nice. It was on time and the food was. Airplane food, but not horrible

No food/snack served during the flight. Crew wasn’t interested at all. Flew American First but flying low cost with Ryanair is even better

Had to wait on pilot and crew to depart and had to wait to arrive at the gate because they only had 2 crews working. Delays, delays....Planes just keep getting smaller and tighter and they nickle and dime for everything. When will an airline actually wake up and make flying more enjoyable?

We had a very pleasant flight with very comfortable seats and nice staff.

Horribly rude check in at airport, worst in 25 years of flying. All over a simple issue they could have googled to resolve.

Our flight was delayed 5 hours, very disorganized, bad communication, confusion. Only good thing was the crew.

Good. No issues except a slight delay. Crew came in late.

we were delayed because of some safety check that wasn't done or available

It was great. I had never flown on JetBlue before, but would be very happy to fly with them in the future.

The plane was late to leave.. Internet was lousy. TV was not working. when we arrived, We stayed on the plane for a long time before we got to the gate. It took us a long time to retrieve our luggage because they didn’t know what carousel to send them to. It was a bad experience.

There were mutliple delays. There was inconsistent, delayed, and poor communication regarding the delays.

It would have been nice if they had offered more than one set of snacks

Ground crew gave me interference about carrying a laptop and a small shoulder bag, even though I told them I traveled with them all the time. I then placed my laptop bag in my carryon and took out a medical device, and ground crew still tried to give interference. I had to remind them that medical devices don't count towards luggage limits. It was quite annoying and unne

The regular feedback of any changes to our flights. The Jetblue staff were very helpful. Our flights were great. Lots of leg room!

Awful. Not water, or chargers or space under the seats, the plane was very old and poor maintenance, seats really dirty, sticky, seats pockets with wires pinching your knees. Connection with no announcements, plane departed 1.30 hour earlier for an extra stop to refueling in Trinidad & Tobago. Even that we had a 3 hrs delay, seated in the plane in the runway.

Really bad. Uncommunicated stop in Trinidad & Tobago for refueling. Extra stop added 3 hours of discomfort without allowing off the seat. Not even water, or chargers or boarding groups.

Staff were unfriendly and rude. Was stuck on runway for 2 hours after arrival in Boston.

Horrible service. No communication from the crew as to why a 6 hour delay then cancellation

We waited in an overcrowded bus for over a half hour. It was uncomfortable. It would have been better to have waited in the terminal in a line

The food for sale on board has opportunity for improvement.

I paid extra for a comfortable seat in the second flight, but the plane didn't have those seats, the first one did

The Arajet person who greeted us initially was unhelpful & rude about the mandatory migration form which has to be completed digitally but the systems don’t work properly. The boarding gate was changed twice and initial boarding was delayed. Once on board we we had to wait an hour and a half before take off. It was hot and there was very little room for tall-ish people to fit their knees in. The crew were pleasant but working in a poor situation. The plane was delayed because we were waiting for people from a delayed interconnecting flight. Arajet must have known that before we were asked to board. Better information, decisions & communication were needed.

My seat was broken and the crew had to find me somewhere else to sit. The crew was extremely courteous about this

Our outgoing flight was cancelled two hours before boarding and Spirit was not able to get us onto another flight. Their customer service was slow and unhelpful.

Terrible. I never made my trip to Puerto Rico and my layover flight from IAH to MCO was delayed over 3 hours and made me miss my connecting flight. I spend 2 days in an airport just to have to go back to Houston. This was a trip for my birthday and I lost money on this trip. I understand the situation with Venezuela affected flights but it’s always something with Spirit.

The flight was on time, the crew is friendly, and the seat was nice and wide compared to some other airlines. (the KAYAK survey should allow for the response, not applicable, because I did not have any food or take advantage of the entertainment)

Every Spirit flight we took was delayed by nearly 2 hours. We arrived in MCO and learned that our connection had been canceled. There were no options for rebooking for 4 days. No hotel vouchers provided, no transportation etc. The airline essentially stranded us, and rhe passengers from 6 other flights hours from our destinations with no assistance. Still no word on my refund. Terrible customer service.

They canceled the flight at the last minute! No customer service. Unable to get another flight for 3 days!! Spirit was NO help at all!!

Flight cancelled. Only options are to a different city or wait 2 days for a flight to same destination

I knew what I was getting into, but never again. Hour long bag drop. 1.5 hour delay. 1 hr 45 mins sitting on the tarmac after landing. They lost a bunch of bags but luckily not mine. Awful experience.

Absolute disaster. Was delayed, delayed again, then delayed while loaded, causing many to miss connecting flights. However, spirit had only one person to process over 20 missed flights, taking forever. They then provided little guidance. No wonder they are bankrupt

Loved that all flights were om time or early. Hated all the additional costs for a seat and luggage.

Honestly horrible. The plane on the way back was delayed 6 times with no explanation on why. When I asked for a refund or some money back because I had to miss a day of work because of the desk, they told me no. Because of how poorly it was handled I will most likely never take spirit again
