It was good. Last flight was delayed but I always say that is in God's plan

It was just okay, no frills, basic transportation with no luxury. No screens on the seats, no water or drinks on a short flight. Full flight but at least it was on time.

Plane was clean and comfortable. Flight attendants and gate staff were professional, friendly and efficient. Boarding and deplaning were orderly and efficient. All in all, the typical excellent Southwest experience.

The seat was not comfortable. 1D. My back was sore all night and the next day.

The new boarding process was easy and straightforward. Very pleasant.

It was as expected and I was grateful for the wheel chair help and ease of use.

No food or entertainment, just a quick 40 minute flight. A little bumpy due to Santa Ana winds but pilot has no control over that. Good flight and landing!

The flight was delayed about 20 minutes, but this was an evening flight, so it comes as no surprise. This flight came a good 1.5 days ahead of hurricane Helene which was still far out in the gulf. However, the flight never removed the seated buckle light. The staff announced from the beginning that due to the bad weather (I suppose the hurricane a day and a half away) they would have to do an abbreviated service with water and a snack. I am fine with their water and snack offering, but this was one of the smoothest flights I've had in years. If Southwest believes a flight like this requires everyone to remain seated, then all of their flights should remain buckled for the entire flight. I cannot help but wonder if things like this are a sneaky way to cut back on expenses since the airline is currently under a lot of pressure to reduce costs.

Although the flight was delayed, but the crew was amazing. They did the best they could to make the time enjoyable.

My experience was find with Southwest. The only issue I have is...at the exact time for me to check in...I don't understand how I always end up in C.

Flight delayed due to ground hold. Republic airways did a great job.

The flight was smooth, the crew was great but the plane was quite old

Delta is always a wonderful experience. A clean plane and the crew is really friendly.

Flight was warm for first few hours and quite rough

Air travel sucks. It continues to be awful for all airlines. No shame on delta alone.

Flight was delayed several times. At one point, they "pulled back" 15 minutes from the delayed boarding and sent a text saying we would board sooner than previously advised. The flight then was delayed again. And when we boarded, there was an unspecified technical issue which had us waiting in the plane for about an hour.

Everything went well and was good. Nothing exceptional, but no complaints either. Cheap seats are pretty comfortable.

De planning was an absolute mess. We were never told that we weren’t at the gate and that we had to go down unstable stairs and then hop on a bus. People were falling, we couldn’t tell who was in charge. Overall terrible communication that ended up leaving a bad impression at the very end of the experience.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

Long line to check bags. Curbside check-in was closed. Seat back monitor was not working.

Crew and agents misguiding on tight connections, and lack of connecting crew looking for inbound planes. A very avoidable missed connection as a result.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

American Airlines changed are gate no fewer than four times. Walking back and forth from one concourse to another was exhausting, especially after all the flight delays.

Hydraulic leak caused the flight to be cancelled. Auto system scheduled us on a 3 am flight. Wevhsedvrebook on the app and hit schedules later in the afternoon. Our luggage per gate and ticket agent would be rescanned and put in our new flight. Did not happen. Our luggage stayed in hsv. Baggage claim in wash dc unable to help. We filed a claim. Several emails about our luggage were in conflict with one another. Called as baggage and was on hold 30 minutes. Oscar said one of 2 was out fir delivery then cancelled. About 45 minutes later both pieces were delivered. Their system is suspect

The airplane was an old model, the overhead didn’t have enough room for people’s items and made boarding and boarding disappointing and stressful. Crew allowed passengers to bring more than the permitted baggage sizes.

It was great. Smooth flight, comfortable, left on time and landed on time.

Horrible experience upon landing. Probably more due to DCA utter incompetence than AA.

Easy boarding. Rows are smaller but that may be an older and bigger me now :)

Flight has been delayed every time I've ever taken it. Seats uncomfortable. Children behind me yelling the entire flight. Some of this is out of their control but overall just consistently not a great experience.

Poor communication ahead of time about flight delays and old planes/other equipment.

We were several hours delayed due to confusion during boarding. Evidently the crew could not match the manifest with the boarded customers. After significant time trying to find individuals on board, a crew member walked through the entire plane re-scanning each of our boarding passes. Then we had to wait for a new slot to depart, and when we landed, our gate was not ready. It was a complete goat rodeo from start to finish.

My checked in luggage cost was $59, almost ticket price. The first 13 rows were empty, but fly attendant did not alow women with little boy change her middle sit, sweet boy was crying, I am so sorry for mother and passengers. At the end of the flight the cabin became impossible cold. Only good was timing of departure and early landing, but it suppose to be normal.

The gate attendant in Boston had a high raspy voice and spoke much too fast to be understood. Not pleasant.

Flight was quick, less time than expected, and the attendants all friendly and helpful. We had paid extra for more leg room and were very comfortable. Haven't flown JetBlue in quite a while. Glad to be back!

I specifically choose not to check bags to ensure I can proceed directly to ground transportation upon arrival. However, due to a recurring lack of cabin space, I was again forced to gate-check my rolling luggage after going through my luggage to take out electronics and batteries. This practice unilaterally changes the service agreement made at the time of purchase. JetBlue needs to find a better way to manage overhead space that honors the carry-on baggage allowance.

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

The flight was two hours late due to a computer fault and resulting maintenance. Nothing was offered as compensation beyond bottles of water during the time we were deplaned and waiting in the terminal.

The free wi-fi was great. But, the flight delay was not sustainable. It definitely impacted people schedules and JetBlue didn’t do anything to compensate clients for it

My tv was broken on the flight which is disappointing when you pay for a seat and expect a service

Old plane. No outlets for laptop or phone. Seats worn out. Area around seat dirty.

Crew was kind of grumpy and there was no beverage service at all. Sodas were $4. Disappointing.

There's no seats that lean back with little leg space i wad uncomfortable the entire flight. Your charges for extra baggage is despicable and costly!!

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!

There was no food and no entertainment, so I'm not sure why these are even in the survey, as my understanding is frontier does not ever offer food without a few, not even a snack, and there are no screens so unless the flight safety talk is our entertainment why ask how we liked it?. One of the flight attendants say in the back of the plane as people filed in to their seats, yelling orders about where to put baggage and telling people to hurry up. It was the least professional experience I've ever had on a flight.

baggage clamed had to wait over a hour and half for all people on my flight it was terrible

Both legs of the flight were changed. The day of the flight and length of the trip.

First of all, we never got on the connecting flight to Denver. They delayed our flight for two hours. If we would have gotten on that flight, we would have been stuck in Denver for 13 hours. So we re- routed our flight for a straight through flight to Oklahoma two days later. THEN, they delayed that flight for two hours. After that we were able to finally get on our flight and come home. Frontier Airlines - one of the worst airlines I have ever been on.

The worst. We never made our connection and they did absolutely nothing to help us at the airport.

The worst flight of my life. Never will I fly frontier again

The plane was comfortable. The time to board was way too slow and very unorganized! The crew was not as friendly as normally. The was not a single time that they offered water nor anything!!!
