Delta flights recently are always delayed AND at jfk tney get the gates further away (need To walk 20’ to get to them/all the way at the end of the terminal). Not sure whats happening but price doesnt match experience!

Everything I mentioned earlier - the airbus was more comfortable indeed and the experience was further enhanced.

Delta continues to set the benchmark for traveler-friendly service with minimal disruption and clear communication within the mainland US (coast to coast). I am consistently pleased to be a Delta customer, and this experience once again met my expectations. There was a brief delay departing from MIA due to a technical issue that required the aircraft to return to the gate. However, the situation was handled professionally and transparently. Fortunately, my planned layover allowed ample buffer time, so the adjustment caused no stress. Overall, another smooth and reassuring experience.

Good experience and the flight landed early. There was no food I had or entertainment.

Flight was delayed and no reasons provided. After the passengers were boarded, the crew made announcement that the captain has jot arrived and he would take another 15 mins. All passengers patiently sat until the captain came and started. Terrible experience!

Flight was delayed. No information on why it was delayed. After we boarded the flight, , the crew made announcement that the captain hs not arrived and he will take 15 mins more to arrive. Passengers were just sitting patiently for the captain to arrive and start, Terrible experience.

Totally worth the miles to upgrade to Delta Comfort. Plenty of legroom.

This was my first time flying Delta ever and I had a great experience!

Smallest leg room I've ever had on a plane.

They took all carry-on luggage from Groups 6 -9 - I was group 5 and waiting in line to board - they made me check my luggage too. That then went to baggage claim and delayed departure from the airport. There was overhead room in my seating area - Delta over reacted. Also, had a gentleman next to me that took up 1/2 my seat.

The crew made our experience extremely bad. They were rude and didn’t have anything for kids.

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.

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

I like flying first class, and United has a nice one

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

Seats had less pitch than a regional jet. Food was OK. Have to buy alcohol on US based carriers flying international. Boarding was a mess. Did not have bags but overhead space was gone quick. Would like to see the airlines enforce the one bag over and one bag under policy

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Crew was excellent. This was a relatively long flight though and had very little leg room, and no entertainment.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

The seats are too uncomfortable for anyone over 5ft 8in. I'm 5'10" with a back and hip issue and I was in pai for the full duration of the flight.

Flight was on time and the meal and service were good.

The accessible bathroom should be visible to people in Economy class.

Lexus in first class was absolutely amazing! Beat flight attendant i’ve ever seen.

the plane was so hot!! the air-conditioning was barely blowing. The flight was delayed, and we had to sit on the hot plane before take off for an extended amount of time, waiting on international passengers. Would not have been so bad if it was not so hot. They said it would get better after take off, but it did not.

did not have enough meal for first class passengers so offer us snack

Old equipment, needs upgrade and seat comfort. Internet didn't work 75% or the time.

Update to handle the delay was very bad, crews no smiles or welcome or thanks. Don’t care attitude

No gates avail at DFW so our incoming had to wait 30 mins for a plane to push back because they Had mechanical. We boarded 90 mins delayed and then we had a mechanical. Come on American…do better. Also at my seat the tray table had not been cleaned. Floor had not been cleaned. But captain and flight Att were very picture and apologetic.

Flight was canceled. I asked to be rerouted to OKC and then took an Uber.

I purchased extra legroom so I will be comfortable but the guy behind me is a big guy who keeps on moving and since he is big I can feel his movement at the back of my chair.

Spirit was on time. They maintained updates and information. The crew was friendly and professional. Because this is a budget friendly airline, they have dispensed with a lot of frills and part of that comes with a price, for example, the seats are not quite as comfortable as others. I am ok with a pay for beverage and snack service as I prefer my own anyway so this was not a concern. I thought overall, having a great flight crew and on time service was definitely worth losing some of the frills from other carriers.

Sadly there was a crew member very rude with my kid and with me.

They canceled the flight and didn't assist in getting a new flight on any airline. I had to spend 10 hrs in the airport after getting a ticket On Delta for twice as much. I've flown Spirit many times and this was my worst experience I've had.

Late taking off. ATC sent us circling around Chicago for almost an hour, after landing taxied for 40 minutes.

We had too many delays for the crew not the plane

Awful!!! Spirit cancelled my flight just 4 hours before departure- with no alternative flights available. I ended up missing a huge family gathering because I wasn’t able to get out. Such An awful experience. And on top of that, all the buckle and dime-ing for bags. I will never book with Spirit EVER

I'd have like to check my bag and not toss my hair products.sears are very uncomfortable. And that even water isn't free really sucks. The ticket was almost $400

Terrible. They cancelled the flight at the last minute after I had checked in at the airport and then told me they could only put me on a flight after 7 days. Pathetic.

Spirit cancelled the flight very late last night, I was on the way to the airport when I found out
