Okay, not wonderful. Short flight. Wi-fi didn't work properly. Stuck waiting for a gate to open upon arrival for 20 or so minutes.

Okay, not wonderful. Short flight. Wi-fi didn't work properly. Stuck waiting for a gate to open upon arrival for 20 or so minutes.

They sent a notice that they were boarding an hour early. We had to leave the club and run to the gate. They said sorry, that came from corporate and was a mistake. They did not have enough seating because the flight before it had not taken off on time. They moved our gate and delayed it for an hour.

The boarding and seat assignment system no longer works for me, but I know it is being replaced. Otherwise, I am good with the overall experience.

The lead steward kept singing about "San Francisco" and hotel California---more annoying than humorous....needs work. Flight was smooth and on time.

Still a fan of open seating. Flight was on schedule and arrived on time. The 737 MAX is very comfortable.

Airline travel is always too cramped to really be pleasant, but the cabin crew on this flight did a pretty good job of making up for it by putting on some music during boarding and sprinkling a few funny remarks into the safety briefing and announcements, and just generally being friendly and helpful. It definitely reminded me of why I prefer the in-flight experience on Southwest!

No delays and arrived to destination 30 min early. Staff was super friendly.

San Diego airport is brand new, spacious, airy and very smooth checkin at SW baggage drop.

It was rough. The staff was unprofessional, the choice of on board drinks terrible, it was cramped in space at every airport, they always ran out of overhead bin space so they pressured people to check bags for free or we couldn’t leave on the plane— so I did check my bag to help, and they nearly lost my bag. My bag did not arrive on the luggage belt, another man on my flight and I had to waste our time going to the baggage office to search for our bags. I would only fly southwest again if it was my last choice. Also, my flights were consistently delayed over and over again— at one point they straight up told us we were waiting for the pilot to arrive.

Crew could have been friendlier, maybe I'm spoiled by SW crews. In flight wifi was good. Would be nice to have more food offerings on a 4 plus hour flight

Flight delays both to Detroits and return flight . The flight to Detroit was associated with mechanical difficulty

I am extremely disappointed that delta internal pilot manuals now refer to the Gulf of Mexico as the “gulf of America”. You can bow down to the Orange turd on your own. I will never fly delta again

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

I noticed that the planes seem to be outdated. There was no entertainment per se. Also, the waiting area did not have any working electrical outlets

None of the airplane features were available during the flight.

Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

The food is terrible. The staff is wonderful. Comfort is good.

Left on time, a bit delayed due to headwinds most of the trip.

The boarding by groups is pointless. The first two groups worked fine, but almost Noone boarded in goups three thru five leaving the vast majority boarding when group six was called. It defeated the purpose of spreading out the crowd.

I don’t know who decides what food to serve on these flights but I would be so embarrassed if I served this to anyone and call it food…

For whatever reason, the flight was not catered -we were told it would be a 45 minute delay waiting for catering - so no food. There were opened candy and peanuts in the seatback pocket. Flight landed early in DFW but due to the assigned gate not being available, we sat on the ground for 30 minutes waiting for the gate to open - making the flight actually arrive at the gate late.

Not great. Booked Extra seats and got nothing extra at all. It’s basically a big budget airline.

The pilot greased the landing and the crew was fantastic.

I bought wifi and most of the flight could not even use it my apps would just spin. I couldn't even listen to music. super frustrating.

delayed due to weather. Could not communicate with family since the wifi was broken

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. :)

Flight was delayed 17 hours due to aircraft issues. American did provide hotel, transportation and meals, 3 hours past boarding time, but it took us another hour to get the vouchers.

Flight was on time is the only good thing. Person loading the plane called 1-6 to board at the same time, made it chaotic. Plane was too small for even putting backpacks in overhead. Seat for normal sized people were too small. The WIFI didn't work. When we landed had to wait because not enough ground crew.

It was good. I prefer JB over other airlines.I just wish we had headphones for the films, but other than that - good.

The ride share experience in JFK is terrible. After traveling on a flight, then you need to take a subway to the last stop to get an uber or lyft. Unacceptable. Bad job JetBlue for permitting JFK and Port Authority to do this to your passengers.

Checking In on JetBlue site was impossible. It hung up on REAL ID. Even my Global Entry did not help. Luckily, on Kayak site it was a breeze. Entire flight the temperature was COLD! Otherwise the crew was great!

The flight was two hours late due to a computer fault and resulting maintenance. Nothing was offered as compensation beyond bottles of water during the time we were deplaned and waiting in the terminal.

Very pleasant flight attendants. Gate crew rather loud chatting with each other.

Four plus hour flight delay in New York caused us to take off after 11:30pm. We didn’t arrive at our hotel until five hours after check in. Started the trip off feeling exhausted.

Plane was in bad shape. TV’s and WiFi didn’t work. Plane need a refresh. Not enough room for bags.

There was a fowl odour coming from the lavatory the entire flight

Everything was great. I liked the text updates so that I never miss a gate change & I have all the latest info.

I don’t usually fly budget airlines or airlines in the United States. It was as good as any other airline. The seats are comfortable and the airline attendants are not rude & surly. Very nice flight (s).

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

First time in a decade I threw up on the flight, turbulence was terrible!! The staff were kinda rude at times.

Boarding was good, clearly explained and efficient. Staff were helpful, I would've liked a place to get coffee that wasn't Starbucks

The most horrible flight ever not only Spirit delayed our flight 2 hours departure time for a 1 hour flight — that I could have driven FLL to TPA and spend less time on the road —- and they did the same on the return with 2-hr delay again!!! Then to top all, the rubber like and most unconfortable seats in the industry with no leg room!!! There should be an award for these kinds of companies measuring % of returning customers!!!

The flight was cancelled and Spirit said they could not rebook me on another flight for six days. They said they couldn't do anything for another six days.

Flight was on time, Newark staff, especially Nathan, very helpful, and plane crew to RDU very good without being pushy. We arrived early, and had a gentle landing.

See my last comment for the first leg. That should’ve been in here

Horrible. Arrived at my gate at 6:37 for a 6:50 flight and was denied by staff to board. Literally watched my flight leave from the window and it didn’t take off until after 7am. Tried to talk to staff and they were rude beyond compare. Will never fly with this airline again.

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

We had to sit and wait for almost an hour after landing and taxiing to the gate. The jet bridge was broken so we just waited and waited and waited and it was inconvenient, hot, and unnecessary.
