Was unsure of this flight due to high winds in CVG from Hurricane Helene. Crew did a great job of getting us to CVG safely.

Was unsure of this flight due to high winds in CVG from Hurricane Helene. Crew did a great job of getting us to CVG safely.

It was not in Delta's control, but when we landed, we ended up parking at the wrong gate, and so everyone was already ready to deplane and had their carryon bags, ready to leave. But we had to sit down and move to the proper gate. This process took over 30 minutes. Again, not Delta's fault - more so on the staff at JFK

Don't waste your money or points on first class. Delta first class is a joke. The seats were rickety, the food was awful, and nothing worked, wifi, my light, the power plug - and it was dirty - the fold out table was gross. For 2-3 hours, tough it out in Economy.

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

My seat had no padding, it was literally plywood with a plastic cover. I could not change seats on my 10 hour flight. My excitement for this trip helped me deal with the pain.

Overall, the flight from Atlanta to Orlando was acceptable, albeit delayed and the typical temperature issue on the plane (hot) which has become somewhat expected. However, the staff at gate B22 for connecting flight DL1562 was disappointing. And to clarify, there were two gentlemen behind the counter — one pleasant and the other, Larry. Without question, Larry should not be in hospitality. My wife and I were first in line and when Larry walked in behind the desk, my wife greeted him with “Hiii Larrry”. And while she can be bubbly at times, and I get that it was late, the conversation morphed as Larry asked if she was drunk. At first I assumed he was joking (still not appropriate) but he was not. Clearly he was having a bad day or maybe just hates his job. In all cases, his behavior was unacceptable and offensive. The only saving grace is that he was equally rude and dismissive to all of the surrounding guests as well—although, I’m not sure if that is a good thing or not.

I specifically picked out right side aisle seats because my left knee sometimes needs to be stretched. But my experience this trip was that the seats were shuffled and I lost those assigned seats, resulting in me having to sit in a much less desirable position for my comfort.

Delay getting into gate in ATL caused delay in bags when getting to BWI, disrupting evening plans with family.

They separated our seats and moved us to the back of the plane. Hundreds of dollars and thousands of miles used and this was my platinum member experience.

New boarding doesn't make sense. Filling front first is slow.

Communication with the customer and stay is important. Staff off with a minor inconvenience but it worked out of course. Also this was a very old Mint Class plane. They snuck this one in on us. The updated aircraft are much better.

The flight itself was fine, but the boarding process was extremely frustrating. There is no one scanning boarding passes - passengers just scan themselves and enter the jetway. By the time my husband and I got on the plane and were halfway to our seats they determined there were too many bags on the plane and everything at that point needed to be checked. This created a lot of unnecessary chaos. They should have alerted people before getting on the plane that they would need to start checking bags instead of waiting until people were already on the plane.

The best flight I’ve had in a while. The plane was like 25% capacity, if that. Smoothest boarding and deplaning process I’ve ever experienced. Wish all flights were this smooth.

Did not enjoy this flight at all. All of my coworkers flew delta and I chose JetBlue because I really value how simple the WiFi and entertainment is and this flight I didn’t get either. Crew staff was unsympathetic to my system not working, everyone I asked for help with was extremely bothered by my request for help.

Little snafu at boarding. Staff communicated with gate poorly. Flight attendant was rude making disembark early. This was an older mint class. Needs an overhaul for sure. Food was good. The male flight attendant was really nice.

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.

Everything was great except for some reason crew and ground crew could not figure out how to deal with an electric wheelchair and it delayed us 20-30mins. Was pretty frustrating for passengers and the captain.

Like the space, did not like the snack options, there was no power outlet in seats, no entertainment, no flyfi.

Traveling with JetBlue from NYC was convenient as accessing JFK airport was straightforward via the LIRR to the AirTrain. Maneuvering through the terminal was hassle-free, which was a pleasant start to the journey. However, the flight experience itself left much to be desired. The seating arrangement was notably uncomfortable; despite securing a window seat, space felt cramped. This was exacerbated by the middle seat passenger encroaching on my area, which made the flight less enjoyable. Additionally, while the in-flight entertainment system initially seemed like a reprieve, the sound outlet on my seat was inoperable. This issue turned what could have been a manageable three-hour flight into a rather tedious ordeal, as I was unable to use the entertainment system effectively. While JetBlue provided a smooth process in terms of airport logistics, the on-board experience highlighted areas in need of improvement, particularly in terms of comfort and entertainment system maintenance.

The flight crew that we had in our section may have been tired or something. I asked the flight attendant about my son’s screen not working and she spoke down to me like I was stupid. He still had no working screen throughout his flight. The other members had no personality and seemed like they were annoyed when you asked them for something. Definitely took a hit for simple things on my JB experience.

Short flying. The seats do not recline at all and very uncomfortable.

Good plane, crew, and flight. Boarding was a bit chaotic. Bathrooms were unacceptable. United DESPERATELY needs a new terminal at IAD.

Flight was on time, crew were excellent. For some reason our originally selected seats were changed. We had to re-choose our seats when we checked in online and options were limited. One of our two checked bags we placed on the wrong carousel. It was only be shear luck that I saw it. That cost us 20 minutes of wasted time. So much for the “priority” tags. They are meaningless, and have been ever since they were implemented. I wish you would do the save some money and stop using them.

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Haven’t used United in a while. Was surprised with the free blanket and earphones. Service was great. Huge plane. 9/.row.

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

No access to the Wi-Fi, noisy group of people made it difficult for me to hear through my earbuds. Snacks and drinks - limited service when your seat is at the back of the plane - people up front are always served first and the back gets whatever is left. Not pleased.

They had three choices for snacks - but you could only have one - and they ran out of the dark chocolate before they made it all the way down the aisle... Packed flight - limited service.

Charlotte NC agents were great and ended up with decent seats after having to switch flights amidst Hurricane situation. CMH was a different story. Doors to flight closed 15 minutes before departure so we nearly were left behind. Flight crew were OK but nothing to brag about for sure

My initial flight to ORD was extended without reason. We circled the airport a few time and then drove on the ground for at least 20 minutes. These kinds of delays are annoying but somewhat expected… it would be nice if the crew would make an announcement to give updates on how long we could expect to be delayed.

It was on time, which is always a good thing. There wasn’t any food hence my okay rating.

Always a great flight on AA. PHX to DFW and vise versa is always going to be a pretty full flight but the crew handles it phenomenally.

I had a TERRIBLE experience with the AA crew. I believe it was disability-related. It’s unlikely I will fly AA again.

Airlines changed our originally booked flights. Our luggage was completely damaged.

Great - quick boarding and landed early with an available gate.

Not too impressed with them to be honest. They had forgotten my gf meal, despite the fact that the app had notified me that it was sorted. Apparently there is a ‘glitch’ in the system, according to one of the stewardesses, and has been for a while. Also the legroom in economy is way too small (and I’m a slight person) and are very uncomfortable. An extra Internal flight I booked via the app, had not even given me the option to order a meal, so was unaware of that and left without food on a 9 hr. flight !! Don’t think I’ll use AA again after this.

Baby cried a lot. Nothing anyone could do about it. Just part of flying.

The flight was uneventful. What was a problem was I was delayed getting home one entire day because the flight from Sacramento was delayed. That made getting to my connecting flight impossible. I had to stay another night at the hotel and incur that expense as a result.

No frills, cheap price & flight was on time, I'm happy.

All the steps below was great!!! and the price thank you!!

I fly almost weekly & Spirit is well worth it & Hands-down, my favorite! Out of all the airlines I fly, I often find that spirit has the cleanest planes & the most well taken care of, typically, I will look up the aircraft registration and often the planes are less than seven years old. Two weeks ago I flew on a Jet that was less than a month old. The crew are often times the most friendly in the air. For this particular flight, I had a very stressful day and was not anticipating a very wonderful flight due to the passing hurricane. We had a half hour delay once boarded due to the weather and changing flight patterns, however, as soon as we turned for the runway, the pilot battling a strong crosswind quickly throttled up and in matter of moments, we had the most peaceful flight. I think I’ve ever taken! And we were still 6 minutes early!!! The personality of the crew was wonderful, typically, for this route the passengers are a little less than desirable but they are professional & very accommodating. Because of the best prices spirit often gets jabbed, but the reality is why pay for anything you don’t need. And you certainly are not sacrificing service!

It was cancelled unexpectedly so we rented a car and drove home.

Seats had more cushion in this flight. Otherwise, I got what I paid for. Will avoid spirit airlines at all cost.

This is the first and last times I take spirit. It’s really bare bones. That old saying that everything comes at a price, that’s really applicable here.

Quick flight. But crew was late so boarding was delayed. No food or entertainment as flight was an hour so no possible eating there…flight was also delayed but I think that was the fault of SAN airport not spirit…

Everything that was available was excellent. Spacious and comfortable, with lovely and helpful crew (one was having a bit of a sour day, but that happens). We sat on the tarmac for one hour and seven minutes waiting for our gate to clear in SAN, but the pilot kept us informed and, amazingly, was very professional in not ragging on the airport (whose fault it was).

Flight was delayed 8 hours so far. Don’t expect to fly when choosing Spirit Airlines. I will happily pay more to never deal with this company again.

The first flight was delayed which would've caused me to miss the connecting flight. It wasn't the first delay of my overall trip with spirit airlines. They were both due to crew. I was offered a credit after I cancelled my newark flight, but honestly, I won't be flying with them ever again. It's absolutely ridiculous that a full refund isn't given considering it wasn't something mechanical or weather related. It's literally their own crew being late.
