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 Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.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.

horrible service, food was an embarrassment, no charging for cellphones, stay away

Great experience with a crew always thinking in the passenger

Good crew. Boarding delays. Almost two hours wait for the bags in DC.

HORRIBLE, my initial flight was cancelled, they made me pay $200 extra dollars and that got cancelled as well! After 6 cancellations I decided to get a refund because I needed to get home to my babies. Out of $1000+ dollars they offered me only $40 in refund! Totally unacceptable! The flight that they cancelled I was able to fly it on another airline. I had to spend $400 on one way tickets just to get home! I’m still getting the runaround.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

Seated dude next to me even though lots of empty rows. But main thing was we sat on the tarmac after landing for 30 minutes because of, in the words of the dude who sat next to me, “operational incompetence”. We got changing directions about where to pick up gate checked bags. Pilot and flight attendant were awesome though.

It was a pretty standard flight... until the almost hour and a half spent on the taxi way. I get that the weather has been poor but the delay had nothing to do with the weather and more to do with a plane with several issues tying up the gate. I get that that happens from time to time but this has been EVERY flight I've been on for the past 5 years and I fly 3 to 5 times a year. This isn't just United... it's American, it's Delta. It's an issue with the entire industry. I work for UPS and packages on a cargo plane get better service than people do these days. Anymore I HATE flying.

I so appreciate the crew members on each flight of United. They are outstanding.

Flight arrived 30 min early and bag was waiting at the baggage pickup. United Club HNL was one of the nicest in the system

Unfortunately weather delayed our flight waiting for our plane to arrive and due to a little snow time was needed to deice the plane so departure was very delayed and I missed the connecting flight

Mean flight attendant. I wanted to reuse my plastic cup, but he (Matthew) said he can't for safety. I then said "I don't want water then" and he poured me a glass. I hope Matthew gets herpes and spends the rest of his life poor, lonely, and homeless.

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

On time on a day with lots of weather cancellations on other flights. Thank you for getting me home during a winter storm!

Don't change gate multiple times make people run across the airport. Announce delays in a timely manner. Have maintenance crew ready. Don't delay and keep passengers on the plane for 3 hrs. on tarmac.

The plane was experiencing problems with the HVAC system, it was very cold in the front of the plane and very hot in the back.

We were upgraded to Business Class. So comfortable with great service and food options

The flight attendant use 1.5 hours to answer my call. My dirty food tray was unattended.

The attendants were kind and helpful. A sugar-free drink would have been very welcome.

Pilot navigated severe weather/snow storm with skill. Described his intentions clearly

one crew said "he" didn't serve double alcohol drinks for travelers in exit rows. crew on prior flight did. Is this a AA rule, and the prior crew was being nice? Also, I think we deserve more than a 25% refund for losing first class seats when rescheduling a flight due to weather

I think we deserve more than 25% refund for losing first class seats when having to reschedule flight due to weather.

The flight was completely full. Crew was not happy. Everyone was rude and brusque. Travelling with an arm in a cast and seating in the first row of economy cabin (in front of the separation) I needed help retrieving my tray for the meal. A staff member literally threw the tray on my lap, without helping to take out the tray. Boarding was messy, with 300 people waiting in an encloses space with low ceiling. I will try to avoid AA next time I have a long flight.

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 check in is the only positive thing in Avianca. The seat is the most uncomfortable I have traveled, the distance is minimal.

Not what it used to be. The sale of food makes them look greedy!

Avianca is not what it used to be. So disappointing

Everything was OK, the deicing took a long time, our connections were almost missed.

All very good except they didn’t load our walker so haven’t gotten it yet

Flight was cancelled. But kayak thought it was still on time.

For the cost you can't e too critical, but the inablitiy to recline the seat and minimal cushioning in the seats made for a less than comfortable flight. Other than that we had an ealry departure and arrival, boarding was smooth.

The flight was delayed by 2 hours and we had no food or water or chargers

Spirit was on time. They maintained updates and information. The crew was friendly and professional. Because this is a budget friendly airline, they have dispensed with a lot of frills and part of that comes with a price, for example, the seats are not quite as comfortable as others. I am ok with a pay for beverage and snack service as I prefer my own anyway so this was not a concern. I thought overall, having a great flight crew and on time service was definitely worth losing some of the frills from other carriers.

Nothing everything cost money a bottle of water is 5 dollars and there wasn't even an outlet to plug 🔌 in my 📱 phone

You can’t beat Spirit’s prices on tickets, especially with the positive experience that comes with it! I appreciated the timeliness of Spirit airlines. The crew in the airport was very kind and wished you a good flight by name. The crew on the flight was attentive and friendly. Overall, I am very pleased with my experience with Spirit.

This was my best experience with spirit. I flew you guys 4 times and I must say this was the BEST

Horribly late because they had no crew!!! And then jet bridge didn’t work!! Then we arrived at a gate at lax miles away that we had to take a shuttle to a terminal!! I was over 3 hours late to getting the LA! Should have been here at 8:30 and at an appointment at 10:30 and arrived and left lax at 11 am!! Horrible experience!!!
