Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

The food is terrible. The staff is wonderful. Comfort is good.

Left on time, a bit delayed due to headwinds most of the trip.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

No lunch on a x-country flight scheduled for 10:50 am departure, arrived 5+ hrs later. That requires a black box label before you pay for the tickets. Worst, when I checked in online, it's specifically said that lunch was served on his flight for economy Plus passengers.

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

Flight team stood out for perzonal attention, kindness at bright cheery attitudes at 8am. Very helpful.

Premium Plus is a really good idea for longer flights

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

The person I bought the ticket for didn’t make the flight.

During booking, I kept trying submitting my payment from the Mexican website and it didn't work. After I had the idea to change it to the Canadian website, it worked but I had to be charged the equivalent of 50 CAD more. I received the clear instruction that I would only be able to check-in at the airport and that it was impossible to select a seat 24 hours before departure, that I had to pay 144 CAD to do so, although not only was I able to check-in 24 hours before departure, but I could have selected my seats for free then. All in all, I almost threw $200 out the window due to misleading information. Besides, the app kept crashing, the information to get to the gate on the app was inaccurate, my gate was switched and I was only informed once in the air (luckily I had noticed the departure pannel), I was not addressed in my language beforehand and even if I tried I was immediately answered in English (which meant the crew understood but didn't want to answer accordingly), there was only one snack & beverage service on my medium haul flight and no beverage service on my short haul flight. To be fair, the planes were comfortable, the crew apart from the language issue was helpful, dynamic and engaging, the plane was clean and the directions were clear and direct. United has a lot of potential to be one of my favourite airlines, but the devil is in the details and a lot of them missed the target.

The worst landing I have ever had on a domestic flight. Thought we would lose the landing gear on landing in Newark. Then we spent 40 minutes trying to position the plane in the right place to be able to get the jet way to the plane. The plane arrived stopped. The announcer was that we were there. Everybody got up, then we were told to sit back down because they had to have us towed to a different position. We got towed and then everyone stood up and they told us we were in the wrong position to sit back down again, and then we got towed to a different position This did not happen immediately. It was 30 minutes while we wandered around a small section of the tarmac in Newark close to the gate, but apparently not close enough. Horrifying experience The CAB should be investigating that flight

Boarding was organized. Plane seats comfortable and service was attentive. Food options were good.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

Flight is clean and ontime. Crew is friendly. Snack can be better and the internet connection is poor

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.

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

it was fine, decent flight... dont get food besides cookies or pretzels so not sure why you ask about food. same for entertainment..

I got sick nothing contagious but distressing and the care I received by Kayla? Keighly the flight attendant will be memorable for ever. Thank You

I got sick nothing contagious but distressing enough and the care I received on the flight was astounding.

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

Attendants were pleasant and the flight was smooth and relaxed.

A little late at the start but all worked out well.

It was fine. No drinks nor snacks offered though. I thought that was unusual.

Flight was in time, very smooth ride and surprisingly lots of legroom in the cabin so I certainly will fly with spirit again

Everything was smoothly and convenient! Just stay in this way!

No free snacks or drinks. Freezing. Uncomfortable. No plugs or entertainment. If you fly to LA the make you change terminals with a slow bus. Awful trip that took forever. Terrible airline- maybe the worst I’ve ever flown.

Was supposed to take off 8:00 last night. Got delayed till 8:00 this morning

When the flight ticket is expensive and you have to purchase check in luggage and there is no snacks, no entertainment, tight seats stuffed in the back of the plane not such good experience. I would like some to reach out to me . I paid for check luggage when I bought the ticket they made me pay again on the return flight extra $70. Very frustrating.

Changing the flight time to 6:15 am on the return flight is extremely inconvenient. The flight was okay. It was on time. The crew was friendly. The seats were uncomfortable. All the upsells are annoying, and I would prefer paying a single higher fee and not have to purchase so much extra.

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.

Although our flight had delays due to three different reasons, it was good. Staff continued to update us which made every one comfortable. We felt the captain and crew had our safety in mind the entire time and no one seemed to lose their patience.

Not clean and was told I would get a great seat and it was not great at all

Flight got delayed for 5 hours no good explanation was offered ;(

Horrible. I would never fly Frontier again. The booking process is tricky at best, but fraudulent in my opinion. Frontier customer service did nothing to rectify my purchase -- I ended up paying more than double what I could have gotten from other airlines and nearly triple what I thought I was buying from Frontier. Their booking practices are unfair to the consumer.

Delayed. Text notifications were slow. Not much information o what was happening. Boarding was slow and confusing. Wasn’t even offered water other flight. Had to ask. No entertainment at all. Felt like.a Greyhound bus.

When I wanted to check in 3 hours prior to boarding time, the employees mentioned “a little over an hour delay” so I waited for an hour then I went to go look for food in the terminal and most people from that flight were in the same area looking for food. Finally I decided after food to check to see if it’s anytime closer and now it’s 2 mins until boarding closes?! What are you kidding me? I didn’t receive anything via sms about boarding now nor via email or on the intercom. I luckily made it through, barely, and then there’s no room for my carry on mind you I’m in the very first row so I had to place my purse in one further row back and my carry on sections down. Not sure who pays for better seats to get your stuff placed all over the plane but that was the worst experience I’ve ever had flying with anyone.

Better than expected. Staff were friendly and nice on both flights.

There was no one at the counter to assist with our check in. The app didn’t work, so I arrived at the airport with time to check in and I couldn’t because no employees were there. When I finally got someone on the phone, it was inside the 60min rule and they said I could no longer check in and they could sell me another ticket. We had to scramble and pay an additional $800 for tickets and THEN AFTER (about 60 min from my original convo with customer service and 10min after original departure time) I had boarded my new flight, there was email saying my original flight from Frontier was delayed and leaving 2hr 50min later, but I STILL wouldn’t have been able to check in. Which means customer service should have been able to see it and let me check in because I was well within my check in time. When I call Frontier, they hang up on me. So their app didn’t work and they employees left and they take zero responsibility or assistance with their “customer service”

Terrible. Flight cancelled with no reasoning and no flights to rebook. Employees were useless and did nothing to help. Did not even know where to retrieve luggage from the cancelled flight. Flyers beware.

No fault of Frontier staff: plane was very late, reached Orlando at 1 am, took a while to get luggage. Weather, gov financial shutdown impact on TSA, air controllers seemed to have multiple flights backed up. Frontier staff seemed to cope as gracefully as possible. It did reassure me that I and my new hip could adapt to travel challenges. Food/entertainment were irrelevant to my trip.

Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.
