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

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.

The staff was very friendly, professional, and courteous. The overall flight was a great experience.

The crew canceled the complementary snack and drink in anticipation of turbulence that never materialized. I was counting on the drink (water) to take the the doses of medication - prescribed for my heart condition - that were due during the flight. Since no snack or meal was served on this flight, I cannot rate the food quality. Otherwise, this flight was excellent.

Departure was delayed more than 1/2 hour while we waited for luggage (only) transfer from another flight/plane. Once approved for takeoff, the flight was excellent.

We got exit row seats both flights. Everything was running on time

Never went on board this flight. Kayak uses Underpricer (which is a scam business) as it's "customer service provider". This customer service is a classic bait and switch "service". I Got caught in the UnderPricer Bait and switch scam. 14 hours on the phone with people from India with heavy accents and upselling me to useless products. The original sell was a flight on spirit. Then they contact me later, an say after they have my money that the flight is no good as is is only one seat for a party of two. I am still in dispute to get my money back. Went to Spirit direct and had a beautiful vacation. I should never have used Kayak and their rip off artists UnderPricer.

The flight crew was extremely rude and especially not helpful when our flight was delayed.

I upgraded to first. Quick and easy boarding. Comfortable seat with power and a nice IPA.

Probably not the fault of Delta but there was delay after delay after delay and I ended up getting home 4 hours later then I should have at 1:30 in the morning

My requested wheelchair never appeared. So many entertainment choices yet, I found little of interest and no internet option to search on my own. Both were minor issues.

No in flight service, no explanation - FC got service, C+ did not, unsure about Economy. No turbulence to speak of, so I guess another way to cut cost, or promote health and well being of Delta employees? Also, boarding in MEM combined zones, and with overhead space already full on both flights after Zone 2/ Diamond, presents a huge challenge to find a space for a bag. Delta, other than point A to B, is no longer reasonable to fly - very poor experiences, not even taking into account the chastising at the gate and rude crews, across the board.

It would have been better if the flight wasn't delayed by 2.5 hours

Delta’s staff is unmatched. From the gate agents, to the pilots, to the flight attendants… all top of the industry.

Delta flight Delay for ,more that two hours i.e original flight was 6.30 PM and it starts at 8.45 PM, When we connect Delta team for meal vouchers as it is late arrival in designation,But we did not get it as per delta policy , which is not good for mid night arrival,

Inexperienced boarding crew allowed too many bags on to a full flight and delayed takeoff causing a missed connection and unplanned overnight stay. There was a hotel at the airport but Delta would not pay for it offering only to shuttle me to an area hotel. Never even offerred so much as an apology by anyone working for Delta.

Staff was great! Kind and cordial! Middle seat row 28 seat B has a hump in it. Trays were getting stuck when putting down and up. Good flight

Departure was delayed resulting in me missing my connection. Delta did not autimatically find me another flight.

Mean flight attendant. I wanted to reuse my plastic cup, but he (Matthew) said he can't for safety. I then said "I don't want water then" and he poured me a glass. I hope Matthew gets herpes and spends the rest of his life poor, lonely, and homeless.

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

Reliable, nice crew, I fly often on that flight and I like it all.

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

The seats were comfortable and we had leg room. Great entertainment.

The flight crew where really good. Better then the crew from BNE to SFO

Delayed, toilets did not flush, pilot parked to far away from Gate

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Safe made to destination. Late to start at GVA for icy reasons but we fought our next fly.

It was good. But the gate team made me check my carry on when there was plenty of space for my luggage on the plane. Otherwise our trip was fine.

The entertainment options were at best, fair. It was exactly the same as my outbound flight. It would have been more entertaining if there were some series from Apple TV, HBO, Showtime or other carriers for me to catch up with.

The comfort of Business Class made this trip far more comfortable. I was indeed surprised when I asked one of the flight attendant to help me set up my "bed", she responded that "We don't make beds in Business Class any longer...only First Class" I believe her name was Giselle, but I'm not certain. She did instruct me how to adjust the seat, place the hooded cover and I clearly understood how to place the blanket and the cover. Additionally, the meal I was served (a beef dish) was almost inedible. The beef was tough and odd tasting. I didn't mention it as I was hoping to quickly settle down and try to get some sleep.

Concern Regarding Significant Gate Delay and Jet Bridge Issue Dear Customer Relations Team, I am writing to express my disappointment with the experience I had on my recent flight AA 2414 on Sunday January 18, 2026. What should have been a routine departure turned into a frustrating and avoidable delay due to an issue with the jet bridge at the gate. As a result, the flight was delayed by approximately 90 minutes while multiple gate changes were attempted. The lack of clear communication during this period made the situation even more challenging. Passengers were left uncertain about the cause of the delay, the expected timeline, and the next steps. This not only disrupted travel plans but also created unnecessary stress for everyone on board. I understand that operational issues can arise, but a malfunctioning jet bridge and the resulting extended delay suggest an area where procedures or equipment maintenance may need attention. I hope you will review this incident to prevent similar disruptions in the future. I would appreciate acknowledgment of this concern and consideration of appropriate compensation for the inconvenience and lost time caused by this delay. Thank you for taking the time to review my experience. I look forward to hearing from you. Sincerely, Dion Dillard

They made me pay $40 to check a bag that was listed as free when I bought my ticket. Then before boarding they offered to check any bags free.

When I got to the waiting area, it was full but when the time came to board, rgete was no plane. The women where you would show your ticket, gave the news saying there was a maintenance problem and that it be an extra half hour wait. We never did see the plane but ultimately, Noone ever saw the plane because there was a fire on one engine. Needless to say, the wait time before it was announced what really happened, was a few hours. Many, many missed their plane transfer because they entered their first train. Also, the electronic info panels up on the different wall for all to see the status of each flight, never stated anything having to do with the long, long hold up. Many people had major problems because they had to swith planes during their trip and that never happened...

It was a good trip. Flight Attendants were friendly and responsive.

Qatar airways ,boarding arrangements at Hamid international airport could been better

Crew in Columbia was not prepared for landing. It was a bit of a disaster and getting bags took forever.

My seat tv didn’t work the whole trip. And the seat space is too small despite being seated at the front.

Even though the plane was delayed from the previous airport, the staff recognized this and kept us informed. The flight crew was absolutely awesome from on my flight from Ft. Meyers to AC. Great experience all around!

Flight was delayed would have liked it to have been on time. I didn't experience the food or entertainment but the boarding process was smooth and the flight crew worked well together and did a great job!

Not seat assigned because overbooking. We could go because some people decided to give their seats.

Spirit loves to pick and choose when to harass you about your personal item. I’ve flown numerous times with the same bag with no problem yet flying out of Orlando they forced me to pay $99 for a carry on and then ran out of overhead space. Do better!

For the price of the fare, there really isn’t much to complain about.

didn't order food on board. there's no way to hold a water botton on the way. otherwise it was a pleasant flight, thanks to the crew.

Even though there was a delay the crew was exceptional.

Even though there was a delay the crew was exeptional

Cheap, only one short delay. No issues despite bad weather. Able to take a big backpack for free.

I know Spirit gets a lot of criticism, but I've taken three flights recently and all were very good, and tremendous value. On my most recent one, they randomly assigned me to a very comfortable exit row seat! The flight was on time and the boarding process was smooth, and the crew was friendly. No complaints!
