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
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.
The boarding process needs to be refined. Sometimes the gate crew call out the boarding zone, and then flip to the monitor to show which zones are boarding. So unless everyone is gathered around to see the monitor there is usually confusion as wi which zones are boarding.
Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.
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.
The only thing to like was that we eventually got to our destination
We will be writing a long, detailed letter to corporate about our awful experience with American airlines.
Food was ok, but not as good as I have had before on AA.
Pretty good. The food was just mediocre, the boarding and crew were good.
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
The delays and cancellations kept me stuck in Miami for an additional 24 hours, and the whole thing seemed extremely disorganized
Flight was late and missed connecting flight. They could have better accommodated, but instead did an overnight and had to arrive the next afternoon.
The flight was delayed leaving Miami. When we arrived in Charlotte, we were unable to park at our scheduled gate. We had to wait another 30-45 minutes before we could park at a different gate. All in all, we were delayed by almost two hours arriving in Charlotte.
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.
It was better than expected. But there were two delays in taking off.
Boarding was easy. I loved that they sat our family together even though we didn't pay for specific seats. I thought $5+ was a lot for pretzels and wish they had a small free snack.
The gate agents for spirit at EWR wouldn’t give me my ticket to board when I arrived 50 min from the flight, saying that I wouldn’t make my flight. They tried to reschedule me to arrive at my destination 14 hours after the original flight, which included a 10 hr layover in another city. I rebooked with another airline and it took me a total of 5 min to go through security. Then I see a charge on my card for a $100 change fee that I did not approve. Beware of this horrible place and these horrible people
Seats are not very comfortable, maybe a little more padding for a 2hr plus flight
Absolutely horrible. Usually pay $40-$50 to check luggage in. I tried to check my suitcase in and the price is raised to $70. That's ridiculously greedy c'mon. I had to leave my suitcase with all my clothes and hygiene products and repurchase once i landed in Atlanta. You guys make it really stressful to travel. Don't even want to travel anymore.
We spent 5 1/2 hours at Ohare cause our flight was diverted cause of rain in the area. We missed appts that we had set on Tuesday and cause we were flying back the next day on the 7am flight we had no time to reschedule anything. Other airlines were landing and taking off fine having no issues. It was only Spirit. Very frustrating flight and I understand why the flights are only around 25-30% full.
The flight was delayed twice with minimal explanation. The terminal and airplane were filthy. The food voucher didn’t even cover a tiny pizza from a kiosk in the terminal. All in all, a pretty miserable experience for a flight to attend a funeral
We sat on the tarmac for an hour waiting for a gate to deplane.
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.
My flight was delayed by two hours which made it so that I would miss my layover flight. I stood in line for customer service for over an hour and when I reached the agent she told me to scan a QR code and it'll give me options. I wasn't offered any help, guidance or compensation, only told that I have options but that I had to figure it all out myself. I was refunded part of the trip and had to buy an expensive same day ticket from another airline in order to get home. I will never fly Frontier again.
