WIFI was great. My selection for seating is an aisle, but during my trip, I never had an aisle seat. If we can get that corrected, I will be thrilled. No snack or drink on this flight.

WIFI was great. My selection for seating is an aisle, but during my trip, I never had an aisle seat. If we can get that corrected, I will be thrilled.

The wifi on the plane is great. The only issue that I have is that I prefer an aisle seat and on my trips this week, I was either in the middle or window. If we can work to secure aisle seating, I will be thrilled. Nice trip.

All good except once again bags took an hour at Midway Airport Happens all the time. Ridiculous

Everything went smoothly and we even arrived a little bit early.

Great vacation. Can't wait till next year for another one.

Great flight but super high price. Glad it was a business trip and not personal

On time. Friendly staff. Took to long to pre bord all the specialty groups. Cramped small plane

The seats were comfortable, and the boarding process was pretty smooth.

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

I didn't take this flight. I changed the flight. Why am I getting surveys and notifications on flights that I change. Seems like a defect with Kayak.

Delta One is extraordinary. I fly business when somebody hires me. I just wonder why there is such a chasm between business class and the insanely inhumane and nonsensical coach. The seats are not large enough to fit even my tiny wife. We fly 10% of what we did because we don’t want to pay 5-10 k but for $400 it’s unbearable. It seems like the accountants took over and made stupid decisions. Screw in 20 extra seats and make it so unbearable that people fly 90% less. Just put the damn price up and put some proper chairs in. But business, yay.

Timing, quality of service, promptness and courtesy of the staff

It was last minute due to weather - considering - it was amazing! Good smiles, friendly staff and they were making sure we knew what was going on when and where.

delta last minute gave me a boarding pass for a different flight with no confirmation that they were changing it

The flight was comfortable and uneventful, which is what I desire

The service from the flight attendants were of supreme quality. They greeted and treated everyone with a wide smile. This is totally absent nowadays. Kudos to them!!!!

Excellent flight and got us around tough weather. Only issue was seat TV did not work and crew tried to reboot.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

was sitting in the jet bridge for 10 minutes in -20 degree weather waiting for my bag

Flight was smooth, quick and felt safe. The 2 delays not happening would have been better but I guess that happens in the airline industry

2 hour delay due to equipment failure. No updates via the app and airport screens (which continued to show a departure time in the past). AA eventually switched planes and the new plane was not catered or cleaned correctly.

Could we please end the loud announcements about credit card offers on your flights? We are trying to sleep, work, watch videos, etc. and if we need a credit card, we will ask for one. Flying is already not what it used to be.

Bags took over and hour to come out. Delays due to wind caused rebooking.

Lower WiFi prices; allow us to see our flight on a map; more variety of drink choices.

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.

Awful. They won’t help me with anything. I booked on American but they abdicated to Iberia. The ticket was overpriced. Everything negative

Waaay too small plane. They also need to up the size of the overhead bins. I would love to keep me 3k with of camera equipment in my hard case baggahe instead of it being thrown into the belly of the plane

After arriving in Dallas, the aircraft taxied for an unusually long time and was unable to park at the gate, which caused a significant delay and made me miss my connecting flight. I then had to wait in a very long line to be rebooked, and I was told that no hotel or meal accommodations would be provided. What is even more unacceptable is that my luggage was mishandled and has still not been located. My suitcase contains important medications that I urgently need, and I have been unable to access them due to the airline’s mishandling. This situation has caused me considerable stress and inconvenience, and I need this issue to be resolved immediately.

Terrible. They canceled our early morning flight after midnight on the day of and had no available flights to rebook my family on for the next 72 hours. Yet they still had other flights that were not cancelled from JFK so it couldn’t be based on the weather. It felt like they canceled the flight based on it not being profitable enough for them. I am not interested in traveling with the again. The absolute worse customer service and lack of accountability.

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

First time flying with JetBlue and never again. I went to the counter to request meet and assist because I'm 74 and my wife is 79. I walk with a cane and my wife is handicapped and has her own wheel chair. I told the agent that my wife and luggage was at the entrance door. The ticketing agent said to me that they don't offer meet and assist. I need to bring them our luggage and then go back and get my wife in order to get my boarding pass. As I went back to get my luggage a Southwest agent along with a TSA agent recognized the situation and came over and took my wife and luggage to the JetBlue ticketing counter alongside the line and told the JetBlue agent to issue to take our luggage as soon as they could.

Flight was fine, price was good but food onboard was abysmal. I was on there for breakfast and lunch and dinner 845am EST to 845pm GMT and all I got was a yoghurt parfait, fruit and a piece of cake. Later snacks included an ice-cream brownie and a pizza twist. I was hungry by the time I landed and the airport amenities were closed. Not happy.

1) No pilot available for 1 hour 2) no room for most passengers careyon in overhead—-> stowed below 3) when we landed we had to wait 45 min. Before docking at gate as gate was not ready

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

Not a pleasant experience, service was poor. Didn't like it

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

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.

Checking In on JetBlue site was impossible. It hung up on REAL ID. Even my Global Entry did not help. Luckily, on Kayak site it was a breeze. Entire flight the temperature was COLD! Otherwise the crew was great!

Very well recently! Frontier is improving and less harrassing customer on luggages! Positive!

Good for a budget airline! It was easy to get on, staff was really nice. Can’t say anything about the food or entertainment because it wasn’t available, which is fine.

I am writing to express my disappointment with my recent Frontier Airlines flight. I was charged $99 at the gate because my bag was said to be too large, yet once onboard there was no available overhead bin space, and I was required to place the bag under the seat in front of me anyway. This made the charge feel unnecessary and unfair. Additionally, before the flight even took off, I was asked to move from the seat I paid for into a middle seat so another passenger and her cat could have my seat to themselves. I was not offered compensation or an explanation for being moved from a paid seat. Between the unexpected bag fee and being forced to give up my seat, this experience fell well below acceptable customer service standards. I would appreciate a review of this situation and appropriate compensation.

It was costly and difficult to check in. $85 to take a small suitcase with me, carry on or checked and $75 on the return trip, Plus $25 if I didn't check my self in check in $25, because I couldn't do it on the kiosk. Small very uncomfortable seats, waited on the runway for near an hour each way. It was my worst flight to date.

It was ok. It was expensive to check 2 bags ($75.00 per bag), and then it took a long time to wait for shuttle to take us from one terminal to the terminal where the plane was taking off at LAX. And all of this for a flight where we had to pay for any food or drink that was not water.

It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option

A 630departure flight Delayed 6hours! They changed my gate, I moved to the new gate. Had our flight on the screen for 12noon departure. I go get above to eat, check screen again and the flight was gone, no notice no announcement, nothing!! They sent my bag on the flight I wasn’t on, got it back to me 3days later. Thank goodness they did refund my money but I will NEVER fly them again.

Due to weather, my flight was delayed, further delayed, then canceled. I eventually got through to a support person who helped me find a different route out of MSP, but to get to DIA, they didn't want to, but eventually did help with the connection ticket purchase. But even this replacement flight was delayed time and time again, and I would have missed my connecting flights and I didn't want to get stuck in a layover city, so after 12 hours at the airport with two young boys who were very tired, we just cancelled our plans and spent the week at home, instead of Nana's.

Plane and crew on board were fine. Everything else was terrible.

The third party booking with cheapflightsfares was awful. Kayak should NOT partner with them. They sold me a bundle including seat selection and carry-on, but did not book the carry-ons with Frontier, so I’m out of pocket for $414 more while I await resolution.
