The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.

The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.

WiFi on the flight was not working. Thus, entertainment options were limited.

Flight was awfully bumpy and landing was a bit jolting. I was in the restroom when snacks and drinks were served and was not asked if i wanted any. I had to ask for water finally.

Crew was great flight was great baggage claim was a failure. It took over 1 hour for bags to arrive. Poor communication poor effort when I spoke to the supervisor about the delay

Planes are aged. The wifi is unreliable and on many fights, no-existent. The flight attendants were very good.

I had a wonderful flight, but the only thing that annoyed me was how crowded TSA was. I still believe airports and all planes work together to bunch everyone together to drive up cost.

Easy to book and to get check in and get on and off.

Everything worked well. Crew was as entertaining as is possible on a plane flight. Southwest still has good legroom:

Glad flight made it out. So many delays due to hurricane. everyone did a great job.

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.

Excellent check-in. Crew was good. Excellent communication from flight deck.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

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

Friendly flight attendants, smooth 8-9 hours flight. Economy seats are small and uncomfortable as usual.

The young man who was our flight attendant in first class was lazy and did not do his job well at all. Never offered drinks upon boarding - actually I take that back... said "are you okay with water" as if I do not want to get you anything else, only passed the snacks around once, got my drink order wrong and then never offered a second round of drinks. He was the worst I have ever seen on Delta and we fly a lot.

Flight left early and arrived early. the whole trip was excellent.

Newer plane, relatively easy boarding, not a full flight and was told that we could not be moved up because of weight and balance issues. Otherwise, a very good experience.

Everything was great. Great service, excellent communication, and early arrival

Flight was delayed several 3 hours - no reason was given and no communication what so ever.

No overhead baggage room even though I was seated in row 2. Consequently had to check in my carry on bag. Baggage carousel was jammed. Took 45 min to get my bag.

Cancelled flight with no specific instructions to get a boarding pass for another flight. The whole flight of people were in line for an hour because there was only 1 person to help at the desk. This was unusual for JetBlue.

Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

Very well organized both boarding and deplaning. Very satisfied with the service I received.

I rate it is good we had a 4-hour travel delay at one point but JetBlue gave out food vouchers and travel points credits for another flight so they try to make up for it

Flight was on time arrived at the destination 10min early they kept in touch via email

My encounter with the entertainment services provided on board was moderate; the functionality of the Wi-Fi connection was either sluggish or nonoperational, while the display screens were antiquated and suffered from poor visibility. On the positive side, the cabin exuded a sense of expansiveness, and the crew exhibited amiable and accommodating behavior throughout the journey.

Food was terrible, all served at once, poor quality . Wine and bread offered only once.

It was one of my worst flight ever. First they were changing the gate for at least 4 times, changing from gate D7 to D12 to D44. Considering the size of the Miami Airport, we are talking about long distance and the train at the airport was not working. Then the flight was delayed around one hour. Then finally we boarded into the plane and when everybody was seated, there was an announcement that there is an issue with one of the tire of the plane, so we all had to get out of the plane with our belongings, to replace the tire. So we had around 2.5-hour delay

No entertainment yatem in flight at seat 51H. Would not shut down either leaving a self moving and openin and changing menus with changes in colors,images brightness levels sort of the type when you get sleep deprivation and image overload when being tortured during an interrogation. 8 hours worth of it. Unable to place backpack underneath seat on that chair. One female stewardess was excellent as she gave up her carryon's space for my backpack but the rest of the iberia crew were very sharp an chtting during the whole flight. The plane did not have hot water so nobody had coffee nor tea. The plane was not up to par to be flying.

I was late from Jacksonville, FL but the limited interaction I had with the Philly crew was great.

The delays and cancellations kept me stuck in Miami for an additional 24 hours, and the whole thing seemed extremely disorganized

The chicken adobo was a little too spicy but good otherwise. My personal opinion. Movie selection could be improved, too many horror movies. Could add a few more chick flicks! The flight was bumpy at times. We arrived a little early too! Flight attendants friendly.

really bad they refused to check in luggages that I had purchased, even showing them the transaction receipt from british airways app the staff in miami was MEDIOCRE

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

Uncomfortable seats and flight attendant was rude as she insisted on waking up my husband to ask him if he wanted a drink. When he said that he was sleeping, she replied “without an attitude “. He was seated at 8c

No food/snack served during the flight. Crew wasn’t interested at all. Flew American First but flying low cost with Ryanair is even better

Although an hour and a half early was told by staff at check in they had overbooked and could not check us in for the flight.

The crew was delayed because they came on another flight that was delayed due to weather 10pm flight left at 1.30 am The airline made no effort to align alternate crew

I liked the price of the flight and the chance to buy a seat with no person seated in the middle seat.. Also the flight was right on time.

Worst airline experience. They were rude and kept changing our seats and/or giving our seats away so our family didn’t get to sit with each other. Almost everyone we dealt with at both airports with this airline was rude. The app kept giving us wrong information making things take longer. Dealing with them before TSA can take close to an hour…longer than I’ve ever had to deal with before. Never using this airline again.

Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.

Cancelled and declined to find alternatives Earlier flight is 2 days later Sent the cancellation notification very late, wish I knew earlier would have stayed to watch the Miami open final game Very disappointing service

They switched my flight to Spirit, Never using Kayak again,

The flight itself was ok and the pilot was very communicative. However, our flight was delayed for almost 3 hours, the gate was changed 3 times and there was no communication as we were waiting. The flight staff was overall a little crabby...I understand as they probably had a long day but we all did.

Asked for a seat change to be w my wife at the gate they were great in sorting it out to make it happen

They cancelled the flight and did nothing. I should be compensated for my uber rides to and from airport. Not a good service by frontier or kayak.
