AC sub par. WiFi not working correctly. Ac sucked. Seats very narrow.

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.

Southwest's seats are the least comfortable I have ever sat in.

The cabin was quiet for the redeye flight. The area was clean. The staff was great. The 787 Max was in good condition. Drawbacks were that the seat widths were tight for some passengers. The seat padding was at best average and for a long flight uncomfortable.

Southwest like most American domestic airlines, is a mediocre airline. But it is among the cheapest. Oh well.

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.

Other than a bit of a delay, everything was good. Again, the boarding process and picking seats is the only thing I don't enjoy.

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.

Better and more food and drinks. Put msnbc and free speech tv on the news channel selection list.

southwest just starting charging for luggage. hadnt realized it until it was too late. now out $70 when i couldve bought a carry on if i wouldve known. free bags was one of the only reasons i chose southwest over another airline (the other being no assigned seats, which is apparently also being changed). stupid business decision. wont be flying southwest anymore.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

Nothing special. The crew never went out of their way for anything.

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

The flight attendants in SLC were rude. I arrived 40 minutes early to gate. Ticket said I needed check in for seat assignments and tried check in and attendants said they weren’t doing it. And proceeded to never call me to give me a ticket so when time to board I received the very last seat. Please relay to employees to do their job better..,

On this flight I felt the food offering was not as complete as on previous flights. The tomato salad was a bit off and there was nothing additional such a bread or butter. The breakfast was only one option, so you either ate what they had or ate nothing. The crew was efficient, but most seemed frustrated throughout the flight. The flight arrived early and was obstacle-free, so I’m overall quite happy, but the shine in the rest of the experience just wasn’t there.

The seats got pretty uncomfortable pretty fast. The armrests are bigger than on other planes, so I had less room in the actual seat. My butt hurt by the end of the flight. :/ comfort was the primary issue. The crew were fantastic!

I believe that a four-hour trip should have a meal. Delta had none.

Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

Flight was delayed and missed my connection Lufthansa didn’t respond.

the delay for 3 hours was understandable due to weather conditions but the flight should’ve provided some on flight compensations or at least provide more food.

United could have one single once of customer service. No human United employee would help me with the invalid mileage plus number, they said I had to speak with the computer.

A little bit more leg room in premium economy. I am 6’4”.

Overall it was good. I missed my connection but I was put on another flight.

Although the flight was delayed the crew and the flight itself were very good. Couldn't fault anything and after the disappointment of being abandoned in the US by BA it was a welcome relief to travel with United

Gate agent did not hold flight for connection, provided no assistance to get new flight

Boarding experience was smooth. Flight attendants were friendly and helpful. Entertainment system on the Houston-Edmonton flight did not function for passengers on the left side of the aisle. On the bird's eye flight from Quito to Houston, they should not serve a meal. No one needs to eat after midnight and it is disturbing for those passengers trying to sleep.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

My Internet did not work for Outlook email or basically anything. I paid for one hour of in-flight usage and it was terrible. I spent a lot of time on different sites and browsers with no luck and a lot of frustration. Other than that, the flight was on time, crew was nice, service was fine. Seat was OK even though I paid for the extra 6 inches. I cannot imagine how tight the seats in the back must be.

Delayed flight that lead to a missed connection and a 5-hour trip became a 12-hour flight 🙄

No issues. They did change our gate FOUR times in about 30 minutes which was mildly annoying but the flight was fine.

Great flight. No issues at all. I still think boarding could be more efficient but otherwise, a good experience.

Crew should be nicer and emphatic with customers. Same cookies as the past 20 years. Seat are ok and the plane was clean though it was delayed.

Very poor delay in dfw was really bad n long

Because of rescheduling, they had to put me on a flight that didn't go through Dallas

The flight got delayed 2.5 hrs due to a maintenance issue that cause a domino effect. American should have spare planes for when something like this happens.

Flight was delayed again and again ultimately almost three hours getting us to our location at close to midnight by the time we got in and out of airport to destination. I had taken time off work to enjoy an evening at destination and that was now wasted

The flight delay in Dallas created a domino effect that impacted all of the connecting flights. It also increased the number of connections. I missed my flight from Casablanca to Marrakech because of the tight turnaround when landing in Casablanca. . CMN airport was understaffed. Only one person could help while other employees were just watching him. It was an extremely frustrating situation. People were crying and slamming their palms on the counter when speaking to the customer service provider, Allabough (man’s name?). Allabough couldn’t change my flight in the system. simultaneously, I was on the call with America. Airlines customer service rep named Solomon that said he couldn’t change it either. So, I took a ONYA voyages train to from Casablanca to Marrakech to get there on Friday June 26. This was unpredictable trip.

Everyone was kind for the most part. I did travel with children and paid for seats and even then it was not as suitable. I tried calling their customer service prior to check in and I was told they couldn't help me because I didn't purchase my tickets with them.

I think the staff was nice. They took time to explain safety protocols. Boarding was great. They started early and our flight left a little early which was convenient. Having free games to play would have been better

Just total easy flight experience!! What could you do better..? Hmmm..? There was nothing I can remember. Spirit was a far more comfortable and easy process than American, United & Delta. I'll always look for Spirit and I've told a few people about, since flying this past trip!! I'm a SPIRIT FAN!! Thank You, SPIRIT AIRLINES!! Very, VERY well done, 100%!! See you...SOON!! -Best, Linda R.

The flight was 3.5 hrs delayed. I was not notified prior to arriving to the airport via spirit app. or via boarding pass that I already had loaded on my phone. The agent that i saw at the counter didn’t mention anything about the delay either. I only saw the update after logging in to my email account.

Better than my las vagas experience, but still dissapointed with the airline support service.

Unfortunately, spirits crew had us boarding and parking the plane often, would wait long periods of time before allowing the people attending the flight on the plane to know what was going on this caused for my plane to not only get diverted but then canceled at an airport 2 hours away and basically stranded with charter buses MAYBE being hired. I was left with no choice but to stay overnight and use a comp room in Altantic City to then arrive home the next day. This trip was the first time seeing my partner since he joined the Air Force and this stressful ride caused unwarranted tears on what was supposed to be an east flight home. I understand weather is unpredictable but to have passengers deboard to then reboard an hour later to taxi on the runway for another hour to then basically leave an entire fight stranded. I waited almost 30 minutes at the airport and not one employee could tell me about a charter bus so I had to leave and make accommodations to stay overnight and get a ride home.

Great! We boarded on time! Everything went so smoothly! The flight was so smooth

Seats uncomfortable, hard to check luggage, etc. It was like the last flight out of Hanoi

I will never fly with Spirit again. I was late getting through TSA after dealing with traffic and getting on the wrong shuttle. I got to the gate 2 minutes before the ticket said the gate closes and they agents were gone and doors were closed. They rescheduled my flight for 12 hours later and the agent had the nerve to tell me, “Be on time next time”. I was already upset from nothing going right for me that morning. I booked another flight through Alaska Airlines and they were very accommodating, nerer again Spirit Airlines!!!!

All was good expecting the seats need a bit of cushion. Besides that I can’t complain.
