All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

There was no food available for this red eye... one little waffle cookie for a 6+ hour flight... thank God I was able to sleep some

For both flights I requested a gluten free meal, they didn’t have one nor were there other options.

Not good , late, and long. We came home so late and spent so much time flying around and taxiing

Terrible. Delayed 7 hours, and cancelled the flight, leaving me stranded and out of pocket $500 for an alternative last minute flight

Food was terrible. Crew was kind but skipped over my row for providing sandwiches and beverages.

Not a great experience. We paid for the upgrade for premium economy seats and seated ourselves in very comfortable seats. Someone came along with the same seat on their boarding pass. The aircraft had been changed and as a result we were booted out and sent further back to small uncomfortable seats. After complaining we were moved to emergency row seats, which gave us more leg room but the seats don’t recline. For people in our 70’s we found having to sit upright from California to NJ very uncomfortable. Not sure why they chose to move senior citizens instead of the two people that were allowed to take the more comfortable seats. Not happy.

More racist flight attandants maybe because i sm an attracticted darkskin latino man but once again bad flight attamdants they ignored me the whole flight even the woman sitting next to me notice how rude they were towards me i really never want to fly united or american airlines they alawsys have the rudesslt and racist flight attandants

We loved the United lounge near our gate and a rep named Aimee who was GREAT

Cramped seat even in economy plus seat 10A. Over booked flight, no space for the bags

WiFi was not eorkig (again) And the plane was from 1990 with the screens which were.not touch and most didn’t even work and if lucky could tune in tv

I paid extra for a seat closer to the front. The TV didn’t work at all for the entire flight. Would have been nice to know before I purchased an “upgraded “ seat

Too many long delays with JetBlue. Worst major airline that serves JFK but unfortunately I keep going back because of the prices.

flight cancelled after 2 delays. left us sitting in JFK at 1am. no customer service to assist rebooking.

To not have food or proper snacks on a 5 hour flight was the worst.

Spend hours delayed with no food, water anything sitting on the aieplane with no ability to eat or use the restroom. My entire experience was the absolute worst. I will never fly jet Blue again.

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 gate and ground staff were excellent, friendly, went out of their way to acknowledge my Mosaic status. The plane was an older Airbus, so the seats were a little worn. The in flight attendant was not very nice, and seemed to be annoyed to be at work or be on this flight. Flight was fast and we landed early and pilots kept us informed.

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

The terminal crew is so rude cabin crew is extremely rude flight is very good

The incoming plane ✈️ was delayed 5 hours en route to Raleigh. My flight was delayed for 5 hours 😢. Finally boarded and then de boarded due to an AC problem. A very tough and long night.

The flight was 3.5 hrs delayed. I was not notified prior to arriving to the airport via spirit app. or via boarding pass that I already had loaded on my phone. The agent that i saw at the counter didn’t mention anything about the delay either. I only saw the update after logging in to my email account.

Unfortunately, spirits crew had us boarding and parking the plane often, would wait long periods of time before allowing the people attending the flight on the plane to know what was going on this caused for my plane to not only get diverted but then canceled at an airport 2 hours away and basically stranded with charter buses MAYBE being hired. I was left with no choice but to stay overnight and use a comp room in Altantic City to then arrive home the next day. This trip was the first time seeing my partner since he joined the Air Force and this stressful ride caused unwarranted tears on what was supposed to be an east flight home. I understand weather is unpredictable but to have passengers deboard to then reboard an hour later to taxi on the runway for another hour to then basically leave an entire fight stranded. I waited almost 30 minutes at the airport and not one employee could tell me about a charter bus so I had to leave and make accommodations to stay overnight and get a ride home.

This was the first time I use Spirit Airlines and was pleasantly surprised. It was a last-minute booking and I was happy to see there was availability on your airline for a price that was affordable. The staff was friendly. The only things I thought were missing, were the ability to recline the seats, although I don’t use that very often, and it would’ve been nice to have power access at the seats to plug in my devices.

The flight was canceled and was bounced around time wise with my elderly parents. That being said the gentleman in custody service was amazingly helpful

It amaze me how other airlines leave on time and Spirit always have some type of delay. I’ve flown with Spirit many times, but it reached a point I’d rather pay twice the amount and not deal with this corporation they never do nothing to reimburse people for their time or headaches.

Too many time late and postponed No electrical power for my electric devices

Flight and crew were good, no complaints at all. Easy, uneventful, quick flight. The delays, cancelled flight, hold time to wait for customer service on the phone were not good. One person that answered told me the delays, first on the way to Newark, and again on way from Newark were due to weather (there was no weather on flight coming in); turns out that was not true. Multiple flights were delayed and cancelled that weekend- 6 for the trip leaving on Sunday from what customer service at the desk told me. Newark was having issues with air traffic controller I believe. So, getting false information and only options of rebook (for another day, or one with stops to get in the next day), refund or a credit valid for 5 years, did nothing to help me get to work the next day or get my son home for school that next day. There was no sort of compensation for the wait or cancellation from airline or from airport. Just out of pocket for the uber ride and the missed hours at work.

The seats! Do not nickel and dime! Be transparent about all your fees!

Seats were new and comfortable. Staff was fine. Missed my connection due to weather -which wasn’t their fault- but got no help at all. Gate staff sent me to customer service, which was and stayed unstaffed. Sign with QR code directed me to call or chat. Chat was useless. Call was returned after an hour. No itinerary offered by Frontier could get me home in less than 30 hours. Rebooked with another airline and got a partial refund that came to about 10 percent of what I paid to get home.

Finally a Frontier on time and efficient. I've had problems before with your airline, but this time everything went fine.

The experience was good. No frills but I got there safe and sound and on time.

Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.

sluggish boarding and arrival procedures, fake nice flight attendants, and lots of delays.

Disaster. They lied every step of the way. We ended up being delayed due to crew and then allegedly abandoned the flight because of a curfew at LGA. No rebooking to LGA at any reasonable time. No hotel. No meal vouchers. Had to sleep in the airport and fly to Newark instead. Will never fly Frontier again.

What I expected, nickeled and dined and a frontier flight attendant loudly complained about her job and lack of communication as she headed to the gate on her cell phone. Not professional.

As every law enforcement agency I could imagine surrounded the plane and we didn’t disembark for 2 hours and then had to stick around for another hour to go get our personal belongings after leaving them behind and being bused away from the plane, it was scary and inconvenient. We were given no information as to why this was happening. Lack of communication with passengers was disappointing.

After boarding and un-boarding twice over 6+hours, the flight was canceled.

Severe turbulence. Captain never came on to reassure passengers after things settled down.
