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!!

As always, the entire Southwest experience was wonderful, from online booking to flight to baggage retrieval. Very grateful.

The weather could have been better. There was a 40 minute ATC delay in SFO because of marine fog and a micro cell storm delayed landing and take-off at Nashville. The gate was changed 5 minutes from boarding from gate B3 to gate C23 at Nashville airport.

After being assaulted by a flight attendant I was then brushed off as oh well because he long braids didn’t mean to whip me in the eye. I have filed complaints and will see. But like any other issue I’ve had with kayak involved it’s been trash. Last time I’ll be using your app

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.

Given some type of snack. Had staff that hated their job and life in general. Have regular overhead bins. The bags have to go sideways and even then, they barely fit. The seats in the front - what would be considered business class were nice. Nothing extra but nice for a short flight. But the regular seats were so close I have no idea how people even fit it them.

Our gate was changed twice, but since they were super close it wasn't an issue. We were delayed 90 mins or so, which wasn't great, but sometimes that's just what happens. Communication was the issue. We weren't kept informed about delays--with more information I would have gotten a real meal, taken a "bio break" and purchased a new book. Because another. flight was being updated more frequently about their delays, I thought ours would be shorter and stayed close by. It left me feeling more frustrated than was necessary.

Your feedback should include a "not applicable" button. There was no food, nor entertainment on our flight. Also, a snack on a short flight will be nice to have

Boarding at BDL gate 24 was confused, but balanced out by friendly, responsive gate attendants. The crew were friendly and made for a straightforward flight. Seats were fine, but the aircraft needs to go in for cabin maintenance. The air nozzles overhead were all loose and could not be closed or adjusted.

Head rest did not move, very uncomfortable. Staff was great. There was no entertainment, would be nice not to have to pay for snack.

Worst airline - on our flight down from MCO to EYW, there was a huuuuuge delay. We were supposed to take off 12p and it was pushed back to almost 2:30p. We boarded the plane and then sat on the tarmac forever because we were "over" weight and had to burn fuel. Rather than ask guests to volunteer and leave, they kept us on the plane. Finally a family decided to off board and take their luggage with them. Shortly after, we left the terminal but then the pilot told us we may have to sit at the end of the runway for 15-20mins to burn more fuel. Which we ended up doing and of course it started to rain. We finally took off 2:50p. We were supposed to land 1p and didn't land until 3:45p. Basically had time to scramble off the plane, grab our luggage, request transportation to our hotel, unpack, rinse off and hustle over to our 6:30p dinner ressy. It's a shame Breeze is the only non-stop airline from MCO to EYW. For this, not sure I'd ever go back to EYW - most def will not take Breeze again.

Flight was rescheduled from (originally) early Saturday departure to a late Sunday departure. Then the late Sunday departure was delayed again (weather) and got in very late. We’ve enjoyed Breeze a lot, but this particular experience was a little disappointing.

Breeze was good but the sandiego airport had traffic and waiting 1 hour in the plane till take off

The return flight was soooooo much colder than the departure flight to Connecticut! I appreciated the layover because I didn't have to change planes. The staff and the service were the best! Everyone was so professional and accommodating. Having internet was great, but for the movies the flight offers through the app could be updated. THANKS EVERYONE! I fly BREEZE every opportunity I can get.

The flight was comfortable with the usual slight turbulence. Macadamia Nuts would be great snacks to purchase in flight.

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

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.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

Delta made it easy, comfortable and timely. The crew was fantastic.

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

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..,

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.

Sat on the ground in Cincinnati for 50 minutes before deplaning

Flight was delayed. Staff at the gate effectively and proactively communicated about the delay.

Overall fine, but the delay was annoying and the reasons for the delay were not communicated. The crew on board were phenomenal!

This flight never occurred because AA couldn’t get their act together.

Boarding was very efficient. Everyone got on board and we got on our way very quickly. It was frustrating that the entertainment app was not functioning properly. I was not able to activate some of the movies offered. The crew on this flight appears to be pretty grumpy. They had no smile on their faces. I felt like they were doing us a favor for being there.

Delayed because of weather in Nashville. I think God or some higher power generally has cursed me when it comes to flying out of Charlotte on American. I'm delayed pretty much everytime. We need Team Cobra Kai types to come in and "sweep the leg(s)" of the Charlotte ops people on principle. Don't let the sweet southern rocking chairs fool you, Charlotte is a sinkhole

Long 5 hour and 45 min flight and only one drink service and cookie snack

Newark airport grounded inbound flight and only announced when the flight was about to start taxing.

Terrible. The flight was delayed two hours due to weather. Then when we got on the plane, the first pilot ended up timing out and we had to wait for a second pilot. Second pile came on board and we tax it out. Had to return back to the gate because of an unruly passenger. Then the copilot timed out. Had to wait for new copilot. Also had to wait for maintenance to check for fuel. Then found out the second pilot timed out and we had to wait for a third pilot. Was ready to go and then needed maintenance again for another issue. In the end, it was 2 o’clock in the morning when they announced that the flight couldn’t go because the third pilot and the second copilot had timed out.
