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

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

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

Boarding was quick & efficient; they gave boarding groups due priority; staff & air crew were very cordial and helpful, pleasant flight.

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

Great experience with a crew always thinking in the passenger

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.

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.

The flight was delayed for 1:30 hours for maintenance issues. They should give more information about connecting flights. For a Business Cabin the Crew was mediocre.

Very turbulent trip made it pretty bearable, plus the lack of refreshments served and the lack of any air conditioning before takeoff which took an hour or more.

Flight was late - I was downgraded from first class to coach

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect

Movie selection is good. Crew did not understand mileage program and were no help. Sick later. Food?

Staff on board was excellent. Positive upbeat helpful- like it used to be.

It was nice to have gotten up upgraded to first class with a meal on a three hour flight

For an expensive flight to another country, United has a lot of nerve serving pretzels and no meals (unless, of course, you want to buy something to eat). Unacceptable.

The food is terrible. The same pasta or chicken with bad taste and presentation

The boarding by groups is pointless. The first two groups worked fine, but almost Noone boarded in goups three thru five leaving the vast majority boarding when group six was called. It defeated the purpose of spreading out the crowd.

For whatever reason, the flight was not catered -we were told it would be a 45 minute delay waiting for catering - so no food. There were opened candy and peanuts in the seatback pocket. Flight landed early in DFW but due to the assigned gate not being available, we sat on the ground for 30 minutes waiting for the gate to open - making the flight actually arrive at the gate late.

The pilot greased the landing and the crew was fantastic.

I bought wifi and most of the flight could not even use it my apps would just spin. I couldn't even listen to music. super frustrating.

delayed due to weather. Could not communicate with family since the wifi was broken

Experience was good, however I had a delay due to weather happening and had to re purchase a seat on a new plane for a higher price (could be my own issue and misunderstanding) but other than that situation. First time flyer (by myself) was terrific!! The last from ORD to ALO didn't have wifi, but it was only 45 minutes so I'm sure that was part of the reason. Overall my experience was great! Next time I will remember to buy tickets with longer layovers. The delays really saved my overall anxiety. :)

Flight was on time is the only good thing. Person loading the plane called 1-6 to board at the same time, made it chaotic. Plane was too small for even putting backpacks in overhead. Seat for normal sized people were too small. The WIFI didn't work. When we landed had to wait because not enough ground crew.

Did not understand a single word the attendant said on the pa system. I was glad it was not an emergency.

Gate was overcrowded. Gate agents performed very well. Flight crew was top notch! Efficient & professional & courteous. Both meals not thermalized well. Dinner main dish was actually cold in the center. Almost inedible. Breakfast sandwich was lukewarm.

The boarding was as always, the crew tried their best but not enough. The food was a disaster I had dietary restrictions that were half met because the company did not loaded the food for the flight. The entertainment screen was fine but content was not and also they removed the free messaging option from the flight and they charged 30 dollars for that crappy bandwidth. This flight is not worth the cost and the company is going down on quality.

It was good. I prefer JB over other airlines.I just wish we had headphones for the films, but other than that - good.

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

Qatar Airways only had spicy meals on the menu in economy class. You might want to get food in the airport before boarding.

The ride share experience in JFK is terrible. After traveling on a flight, then you need to take a subway to the last stop to get an uber or lyft. Unacceptable. Bad job JetBlue for permitting JFK and Port Authority to do this to your passengers.

The flight was two hours late due to a computer fault and resulting maintenance. Nothing was offered as compensation beyond bottles of water during the time we were deplaned and waiting in the terminal.

Very pleasant flight attendants. Gate crew rather loud chatting with each other.

Four plus hour flight delay in New York caused us to take off after 11:30pm. We didn’t arrive at our hotel until five hours after check in. Started the trip off feeling exhausted.

Friendly crew. Poor food service maybe due to full flight. All in all, you get what you pay for.

Plane was in bad shape. TV’s and WiFi didn’t work. Plane need a refresh. Not enough room for bags.

Everything was great. I liked the text updates so that I never miss a gate change & I have all the latest info.

Spirit cancelled the flight very late last night, I was on the way to the airport when I found out

First time in a decade I threw up on the flight, turbulence was terrible!! The staff were kinda rude at times.

Boarding was good, clearly explained and efficient. Staff were helpful, I would've liked a place to get coffee that wasn't Starbucks

I really liked the personalized treatment at the MDE airport, where someone from SPIRIT received me at the entrance of the counter line to ask if the weight of my luggage was accurate or if I wanted a better seat, gave me a name tag for my luggage and walked me to the counter. Thank you.

The most horrible flight ever not only Spirit delayed our flight 2 hours departure time for a 1 hour flight — that I could have driven FLL to TPA and spend less time on the road —- and they did the same on the return with 2-hr delay again!!! Then to top all, the rubber like and most unconfortable seats in the industry with no leg room!!! There should be an award for these kinds of companies measuring % of returning customers!!!

I can't rate food or entertainment when previously you know the lowest rate doesn't have any of that included. However I want to congratulate the crew and specially the flight attendants for their kindness and free smile even knowing is the end of a long day. I had the opportunity to chat to Hailey, Despise her busy job, she had the time to chat with me and even when she asked me to stop using my phone, not with words but with her sweet face expression, was as MasterCard said, a priceless moment. She even told me she learned from the best teacher, her Mom Ruth, a flight attendant working in the same flight, Definitely, with people like them, the real Americans, this country will overcome the worst moment in USA history falling in the hands of the biggest senil Psycho felon. God bless America!!!!

The flight was cancelled and Spirit said they could not rebook me on another flight for six days. They said they couldn't do anything for another six days.

Flight was on time, Newark staff, especially Nathan, very helpful, and plane crew to RDU very good without being pushy. We arrived early, and had a gentle landing.

See my last comment for the first leg. That should’ve been in here

Horrible. Arrived at my gate at 6:37 for a 6:50 flight and was denied by staff to board. Literally watched my flight leave from the window and it didn’t take off until after 7am. Tried to talk to staff and they were rude beyond compare. Will never fly with this airline again.
