I wish they had movie screens in the headrests. The seats are much improved, more legroom and recently renovated. Bathroom was clean. Staff was outstanding!!

I wish they had movie screens in the headrests. The seats are much improved, more legroom and recently renovated. Bathroom was clean. Staff was outstanding!!

Near 4 hour flight with only 1 service. Had to use call button to request water. Internet and power not working until into flight. Internet would stop working during flight.

My flight was delayed 50 minutes and we were rushed to board to then sit for 15 minutes until the pilot arrived. Unacceptable since we could have waited to board. Also the delayed flight was updated AFTER we boarded to more than the 10 minutes as originally stated.

If we are going to have to pay for luggage, make it easier to do. Put something on the app during check-in so I don't need to do it at the kiosk. I've done it twice recently and I ended up having to pay at the desk because something went wrong at the kiosk in Tampa.

Everything was on time. I was disappointed by the front section female, African American flight attendant. I did not see her name tag or would have identified by name not race. As passengers moved to the bathroom early in flight, she would say with a disdainful tone “I have to say the seat belt light is on” then go back to her book. Better trained flight attendants say something like be careful the seat belt light is on.

Staff was far less than helpful at all times. Departure and arrival times mean nothing to Southwest. Extremely disappointed, will never fly with them again, and I’ll be sure to share my experience with all.

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

Wasn't a Delta issue I don't think, but seems there was a Delta flight at each of the 2 Dallas airports at the same exact time, both to Atlanta. I was evidently booked on the one at Love Airport, but the Carey transport shuttle took me to DFW instead and I ended up missing the flight by just a few minutes. Was able to book a Southwest flight from Love Airport, but was a big loss of time and an inconvenience.

Great. I had to modify a flight. That was easy and free. Thank You

We had a lot of really rough weather but that was not Delta's fault. Pilot was amazing.

The ticket agents in West Palm Beach on Friday afternoon Nov. 7th were incredible in getting us on an earlier plane to Atlanta during the government shutdown. Had the taken our original flight we would have missed our connection. She did this on her own, We didn't even have to ask, and she did it all with a smile and showing genuine concern that we would be taken care of. We are very grateful and thankful. We fly often, and now we will be sure to fly Delta.

Flight delayed then cancelled. Misplaced luggage. Still do not have. Rented car 1100 mile drive. I had to buy some overnight Hotels clothes toiletries gas food at my expense. Still not home. Not sure where luggage is. Over 4 hours on hold to Felta

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

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

Non stop on long haul is the way to go. Great experience

Flight was crowded and the woman sitting on my left was large & kept crouching in to my space. You need bigger seats or smaller passengers to fit into the seats you DO have! Snack were OK. Would appreciate if airlines had more savory rather than sweet snacks, thank you!

Delayed flight (1hour) plus a long layover after an overnight flight with no backup plane available.

Experience was good, however I had a delay due to weather happening and had to re purchase a seat on a new plane for a higher price (could be my own issue and misunderstanding) but other than that situation. First time flyer (by myself) was terrific!! The last from ORD to ALO didn't have wifi, but it was only 45 minutes so I'm sure that was part of the reason. Overall my experience was great! Next time I will remember to buy tickets with longer layovers. The delays really saved my overall anxiety. :)

I appreciated that it was on time, safe and professional. I didn’t like that I wasn’t in a place where I had a window at my window seat. It would have been nice to know that in advance. If it was mentioned in the ticketing, I didn’t notice it.

I like that the crew kept us informed but we moved back and forth from gate to gate before the aircraft arrived.

The experience with American Airlines was good, although the Philippines Airlines flight was much better (better seats, better food, better entertainment options, overall better). Again, the MIA to LAX flight was fine, but nothing in comparison to the comfort and accommodations of the Philippines Airlines flight from LAX to MNL.

I have a gluten allergy so didn't have any food

I enjoyed the extra leg room compared to other airlines. The first stewards made my daughter’s birthday special by giving her an extra snack. Then the last one coming home from Chicago to Appleton made our night really enjoyable Thanks for making our trip enjoyable

The flight attendant, a black woman with curly hair who sat near Row 21, was wonderful and kind.

The only thing to like was that we eventually got to our destination

We had 3 flights. 1 & 2 were on the same plane but we had to de-board just to re-board 30 mins later. That may have been due to a crew change though. Our 3rd flight had a couple “maintenance” issues that held us up. They were quickly resolved but it took forever for someone to bring the paperwork needed so we could leave. Apparently there was a computer glitch so a driver had to bring a physical copy. It delayed us about 1 1/2 hrs. The flights themselves were smooth & no problems. For boarding, I don’t know why they don’t start with the back of the plane & move forward. It would eliminate the back up from people trying to find their seats & put their bags in the overhead bins. Unless you’re on an overseas flight, there is no food, you get a beverage & either a small bag of pretzels or a biscuit cookie. Take your own food or snacks of you want something more.

Lost bag and 2 days no word leaving for cruise no clothes or stuff

Our flight got rescheduled 48 hours later, the airline didn’t pay a penny for our expenses.

Flight was in time, very smooth ride and surprisingly lots of legroom in the cabin so I certainly will fly with spirit again

The seats are the most uncomfortable seats I’ve ever sat in. Don’t believe I’ll ever fly spirit again!!

Customer feedback I sent to Spirited today: “I will never fly Spirit Airlines again and will work hard to convince my friends and family to boycott/avoid Spirit Airlines at all costs. I booked three seats for me and my 8 and 10 year old children on NK 1222 from Orlando to Kansas City for 12/7/25 leaving Orlando at 10:37AM. This itinerary was abandoned by Spirit and we were rebooked onto Spirit flight NK 213 leaving at 9:06PM without any notice. Then the nightmare really began. Flight 213 was delayed a total of 12 times, finally leaving at 6:35AM the following day. The gate was changed 5 times and our electronic boarding passes were invalidated at midnight. The worst part was that the 12 separate delays were incremental making it impossible to plan for accommodations for my family. My kids missed a day of school and barely slept under the harsh lights with lots of noise on the filthy airport floor. The customer service agent at Spirit Airlines told us we would be emailed a voucher for a hotel which never happened. I asked about it multiple times and it never arrived in my email inbox. This whole unfortunate situation could’ve been avoided if spirit had taken a realistic approach and delayed the flight from 9 PM until 6 AM from the beginning. My son gleefully deleted the Spirit app from my phone once we landed and we will never fly with Spirit again.”

This was my first time on a budget airline and I couldn't even sit down all the way because my knees would embed in the seat in front of me. I'm only 6' tall with a 32" inseam. There's no upside other than y'all are cheap. I'm glad it was only a 2 hour flight. Lesson learned! I get why everybody talks down on budget airlines. The staff was outstanding, the flight went as well as possible, great pilot, great boarding, smooth sailing. Zero chance I'll be back though.

Everything was smoothly and convenient! Just stay in this way!

Crew are always very angry and dismissive like they seem they are being forced to work. In addition, there was a long line for the bathrooms, and only one was allowed to be used. No reason was given for only one bathroom being available; apparently, the stewardess was more interested in using the jumpseat instead of allowing the customers to use the bathroom.

Flight was on time. Friendly crew. Gate agents in the other hand were very unfriendly.

Speaker airport didn't work well, so we couldn't hear the boarding call but the plane was on time leaving and on time arriving took a while for them to open the door and there was a non-disruptive guy who was inebriated a few rows ahead of us. Overall the flight was good and we appreciate the on-time-ness

Bought round trip tickets. Ended up upgrading to first class. Both flights were new planes but hadn’t been equipped with WiFi and there were no charging ports at my seat despite it being new and first class accommodations.

Flight got delayed for 5 hours no good explanation was offered ;(

Delayed. Text notifications were slow. Not much information o what was happening. Boarding was slow and confusing. Wasn’t even offered water other flight. Had to ask. No entertainment at all. Felt like.a Greyhound bus.

There was no one at the counter to assist with our check in. The app didn’t work, so I arrived at the airport with time to check in and I couldn’t because no employees were there. When I finally got someone on the phone, it was inside the 60min rule and they said I could no longer check in and they could sell me another ticket. We had to scramble and pay an additional $800 for tickets and THEN AFTER (about 60 min from my original convo with customer service and 10min after original departure time) I had boarded my new flight, there was email saying my original flight from Frontier was delayed and leaving 2hr 50min later, but I STILL wouldn’t have been able to check in. Which means customer service should have been able to see it and let me check in because I was well within my check in time. When I call Frontier, they hang up on me. So their app didn’t work and they employees left and they take zero responsibility or assistance with their “customer service”

Boarding was on time and plane departed as scheduled. There are obviously no amenities (food, drink, entertainment) on Frontier, but there also didn't seem to be any issues with luggage space either.

Everyone seemed to be in zone 1 for boarding. Maybe break it up a little. Otherwise, smooth flight.

The experience was good. No frills but I got there safe and sound and on time.

sluggish boarding and arrival procedures, fake nice flight attendants, and lots of delays.

After boarding and un-boarding twice over 6+hours, the flight was canceled.

Severe turbulence. Captain never came on to reassure passengers after things settled down.

Boarding in Orlando was not good. Giant mob at the gate, should have been lines.
