Check-in, Boarding and flight were smooth. All the employees and crew was very nice and funny. They gave the kids crayons and workbooks to keep them occupied which was a big win. I’ve flown Southwest many times and that’s the first time I’ve seen that and it is a great addition.

Check-in, Boarding and flight were smooth. All the employees and crew was very nice and funny. They gave the kids crayons and workbooks to keep them occupied which was a big win. I’ve flown Southwest many times and that’s the first time I’ve seen that and it is a great addition.

Flight was on time. Wi-fi was a little spotty/slow. Boarding and exit were efficient.

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.

Did not realize internet screen was hidden between seats and no info printed!!!!

I went to washroom twice and once there was no toilet seat cover and the other no toilet paper at all. I don't think it was ever replenished or checked before we boarded as it was very early on in the flight.

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Very good flight crew and very nice people staff were incredible especially the gate agent

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

The flight was delayed for about 2 hrs. Other than it, it was good.

Advertised fruit trays with cheese, but only snacks handed out!

The plant way delayed departing by 3 hours. It was an old airplane with broken seats and armrests. The bathroom made a hollering sound. A really crappy flight experience and travel day all around.

Premium economy is like the forgotten class. Aside from meal service never saw a flight attendant. Any additional beverages required going to the very back of the plane to request and there was rarely an attendant there. Seat leg / foot rest hardly elevates and not well suite for someone under 5’6. Bulky armrests

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

Pushed back only to get deplaned due to a tire damaged by ground crew. They did at least go pretty fast. The bathrooms should be banned under the Geneva convention. No room to even sit straight on the toilet. The under-seat entertainment units block what little leg room there is.

Essy to get on. The hostess gave very little pop, the plane was late getting in, and we are still waiting for our bags. This sucks. :/

It was good, although we could not get our preferred seats, we did enjoy the whole experience from Costa Rica. I still don't understand why our luggage is not the first to come out at the band.

Great flight. On time boarding. Smooth flight and on time arrival at EWR. The flight crew was marvelous and there was a great selection of movies on the entertainment system. Our bags were at the carousel before we got there. Another excellent flight from United.

everything was pretty good. Houston airport is awful. Unnecessarily inefficient; people working there are rude. Badly run

United airlines has the best customer experience from booking to arrival. I always fly United airlines. The mileage program is excellent

They did the one thing that really matters - got to Chicago early.

I liked the snacks and the flight attendants were friendly.

The flight was delayed for 1:30 hours for maintenance issues. They should give more information about connecting flights. For a Business Cabin the Crew was mediocre.

Very turbulent trip made it pretty bearable, plus the lack of refreshments served and the lack of any air conditioning before takeoff which took an hour or more.

We were 4+ hours delayed. AA is absolutely obnoxious. They just kept pushing back the time to the point where we did not get into Vegas until after midnight when we were supposed to arrive like 845pm.

My last flight on 25 Dec, it’s Christmas Day, everyone happy and very good mood. I really enjoy traveling with Americans Airlines from Miami to Minneapolis my home town after long flight from lhe to Doha then Miami. Thank you again to make my travels comfortable and relaxed. Best regards

The boarding process needs to be fixed. The zone don't work, especially when there is hardly anyone in zones 3, 4,and 5, leaving the majority of the passengers backed up in the aisle, especially because passengers seated near the front are blocking passengers who are seated in the rear of the plane. It would also help if the size of carry on bags was more strictly enforced.

WiFi didn’t work the entire flight. Very disappointing. Minimal food and options - sadly the state of current affairs. All other aspects of the flight were fine.

Great flight - friendly and attentive team! Seats in coach were comfy, but a little cramped - but that is the case with all airlines ;)

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.

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.

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

Delays due to a "power bank removal", no wifi, pilot said wrong arrival city, stewardess mumbled the word drinks as she rushed past, loud passengers with no enforcement of rules (blasting music out loud on their phones), screaming children

They cancelled my flight same day with no explanation why. They offered to rebook me but it would not be until 2 days later. I will never use them again.

Flight was cancelled with no help From spirit or kayak. Please refund asap

The flight was delayed by over an hour. The flight departure time and gate info kept changing several times. Very frustrating boarding experience and inconvenient for families with little children.

I waited for 4+ extra hours to even board when i was fighting off a cold. So i was sitting there in the airport with a fever and chills while spirit wasted my time. Then once on the plane we had at least an extra hour of taxiing before and after takeoff. Really poor airline, no amenities to speak of, and a lack of organization that will just ruin your experience.

Got to LAX at 3:20 am, the counter personnel did not start to check in bags till 3:40 am. I patiently waited at the priority check in line as they started to take people from the general line. After about 15 minutes of waiting, I approached the lady exactly in front of the priority line and asked her if they would be taking people from the priority line or if I would need to switch to waiting in the general line. She responded “yes”, I then asked her yes to what? And she yelled back at me loudly “I SAID YES!” Needless to say, I waited at the end of the line of the general line. I could have been told the priority line would not be called upon and could have queued in the general line ahead of many people that arrived to cue after I did

Very bad. Our flight was canceled and we need to rebook another flight which was in two hours after we’ve known about cancelation. It changed our plans. We had financial and other loses. Nobody did reimbursement to us.

A flight attendant was extremely friendly and offered to move me to a row that was less crowded

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

Spirit has improved a lot since I flew with it in 2011. I give the airline a huge thumbs up!!
