The last 3 flights between BWI and BDL canceled the beverage service mid- way. Just say up front that the fight is too short. Thanks!

The last 3 flights between BWI and BDL canceled the beverage service mid- way. Just say up front that the fight is too short. Thanks!

3 hour delay. Had to change plans and was still delayed.

Never went on board this flight. Kayak uses Underpricer (which is a scam business) as it's "customer service provider". This customer service is a classic bait and switch "service". I Got caught in the UnderPricer Bait and switch scam. 14 hours on the phone with people from India with heavy accents and upselling me to useless products. The original sell was a flight on spirit. Then they contact me later, an say after they have my money that the flight is no good as is is only one seat for a party of two. I am still in dispute to get my money back. Went to Spirit direct and had a beautiful vacation. I should never have used Kayak and their rip off artists UnderPricer.

Check-in, Boarding and flight were smooth. All the employees and crew was very nice and funny. They gave the kids crayons and workbooks to keep them occupied which was a big win. I’ve flown Southwest many times and that’s the first time I’ve seen that and it is a great addition.

Crew could have been friendlier, maybe I'm spoiled by SW crews. In flight wifi was good. Would be nice to have more food offerings on a 4 plus hour flight

Excellent. Would encourage Southwest to keep current boarding procedures with free style seating. Makes for a fantastic experience

Was good. I miss the free 2 checked bags. That was part of what made Southwest special

My flight was delayed 50 minutes and we were rushed to board to then sit for 15 minutes until the pilot arrived. Unacceptable since we could have waited to board. Also the delayed flight was updated AFTER we boarded to more than the 10 minutes as originally stated.

It was a perfect flight in all aspects! Both legs!

Great flight staff. Ease of boarding. Overall, very uneventful and easy trip.

Seats were awful. Media should have been included for such a long flight.

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.

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.

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.

It was a pretty smooth flight, I tend to get mini anxiety attacks during flights, however, this time was pretty smooth and I was able to relax. The only thing, I was having issues to connect to the Flyfi internet. I was not able to connect at all, I turned off my phone a couple times and didnt work.

Both flights were significantly delayed. The flight experience itself was great.

Automated scanning was slow and somewhat haphazard. Too many people were unfamiliar with the tech and were forced to learn on the fly. The hands off approach of the gate staff made it more uncomfortable. This needs work. Overall the flight and cabin crew were excellent.

Crew were fantastic and so catering and wonderful! Full score for the entire crew!

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.

I like that the flight attendant was very attentive and helpful. The meal menu could have more of an variety of food choices.

The gates should be ready when we land. Waiting on the runway for a hour is ridiculous.

Broke my luggage and I can't get a resolution yet.

There were no TV screens - even in Business class. 5 delays, and only given $12 meal voucher! Terrible!

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.

Had to pay for my bag a mini weekender bag 100 dollar fee

The flight from Boston to San Juan was boring since you guys don’t offer wings if during the flight. The returning flight was better offering WiFi to passengers. The food was horrible not enough on stock.serve paying customers better.

Flight out was great but this flight was canceled and nothing was available for 2 days after this so I had to purchase an expensive ticket from another airline so I could go home. The flight cancellation was said to be a crew issue, it wasn’t weather or maintenance.

Forgot my anxiety pills, crew didn’t knew what to do then few minutes after they gave me a bottle of water and told me to walk thru the hall. They should be trained for this kinds of situations cause it really would help someone. Tips: bottle of water (airports should allow passengers at least having them thru) for this kinds of situations. Alcohol wipes just in case they don’t have. Tap water on skin (preferably little cold or a normal temperature) this will help.

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
