The entire experience from boarding to landing was amazing! The crew were very friendly. Will definitely be back.

no service at all due to turbulence. they should've at least given us snacks, there were only 10 people on the entire flight.

First time I've had to use the disabled accommodations. And I could not have had a better experience with Southwest, i was having trouble getting from one terminal to another due to my heart failure. And the next thing I know a Southwest agent had made sure. I had a wheelchair at all my flights. Can't thank them enough.

Delayed flight, lack of information, boarding process is a mess as is the carryon luggage causing issues when leaving the plane….just a poor experience.

Comfortable. Easy. No problems. Just wish they had gf options for snacks.

The crew was very kind and made going to Hawaii relaxing and fun to look forward to! Thank you Southwest for a pleasant flight!

This leg was much better, but we did have to have a 3 hour lay o er after coming from a very exhausting hiccup with our flight from BNA to Den

We waited in the airplane for over 45 min for a southwest employee to make the flight. This cause over half the plane to miss their connecting flight in Denver. When we confronted the desk upon arrival, they told us the only flight they had was the next day leaving at 8:50 pm!!! Or they offered to get us to Burbank or LA, but after that we were on our own to get back to Santa Barbara. I paid for a flight from sba to bna bna to sba. My re entry into mom mode has been 💯 rough because of southwest mistake with my flight. And now I’m leaving to Reno tomorrow for a vballl tournament and just discovered that my leg in Vegas has me and my 3 kids on a stand by flight even though I had booked these ticket last year November!! Do better southwest!

Southwest is kind of a slum airline. It’s gotten more expensive over the years for less and less service. I am a Southwest Chase Visa card holder and was forced to choose a seat in the 26th row in the middle seat. However my wife who is a rewards member but doesn’t hold a card or anything else, gets randomly assigned a normally paid seat in row 6! How does that work?

For the first time in a long time, the Wi-Fi actually worked the entire flight! The flight crew was amazing as usual.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

The flight was very good and the staff was very friendly and helpful!

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Very easy to use and convenient, you can perform any action within the same portal

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

WiFi didn’t work. Flight delayed 3 hours Crew members were illiterate Seat lean back did not work.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

This wasn't my experience with Delta. It was just the Pegasus flight. Seats were very hard. Staff was kinda rough. Not very nice. Charged me for snacks. For a 4 hour flight I would've expected more.

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

They told us yesterday APR21st that they were cleaning the plane and we got delayed. After that they said they didn't had any crew for the flight so they cancelled the flight till next day.

The crew was great. Very friendly and responsive. The plane was old, small and tight. We ran out of overhead space and I had to check. Middle seat was particularly tight.

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

As we approached Denver, we encountered quite a bit of turbulence. I know this can sometimes be the case as I frequently fly this route but not on American. My gripe: Usually a pilot or co-pilot alerts passengers to the possibility of turbulance ahead of time. This did not occur nor did he communiucate during what was a pretty rough ride.

The flight was on time and the landing was very smooth. The crew and flight attendants were all very friendly and professional.

When I booked my flight a month ago - I selected a seat. That seat was NOT the one I ended up with when I checked into my flight the day before. This is the second time this has occurred. So, I checked my next flight on Wednesday and Thursday and no seat was assigned. Poor, very poor customer service.

Cleared standby and gave up my seat. Terrible policy and boarding experience

Message about flight cancelation was received late due to being in the air. No explanation, just canceled and booked on morning flight. We had to stay in the airport overnight because there was no transportation offered to get to the hotel that AA had available. Actual inflight was fine.

Bag drop was very disorganized in Miami. All main cabin passengers were shunted to just a few lanes and they had an equal number of lanes for first class passengers but there was nobody on those lines. They did nothing to bring the main cab and passengers over to the open lines and they just had employees standing there and doing nothing

Flight boarded from Gate 159B, the farthest gate in the LAX Bradley Terminal. While the flight operated on time, the first class cabin attendant made no recognition of my being an Advantage Executive Platinum member.

American Airlines did everything they could with the high Spring Break crowd. I was frustrated to be changed from 1st class to a middle seat at the back of the plane. This has happened before, not sure booking 1st class and paying the extra actually works.

I didn't end up taking this flight. I got up at 4am for a flight that was supposed to board at 6am - at 5:55am you delayed the flight to 10am. The airport is under construction so I switched to a later flight as I wasn't going to sit in the airport for 4 hours. They said the delay was due to the crew needing rest from a flight coming in late the night before - if that was the case then I think you should have delayed the flight much sooner so that passengers wouldn't get up so early and get to the airport to sit and wait.

Plane was hot and miserable and the crew was rude!

12 hour delay required getting on and off plane 3 times - would have at least liked to have been offered a snack or drink

They didn’t offer a water, even after I asked

They switched our terminal 3 times and we were delayed for four plus hours!!!

It was an early flight and most people napped/slept and the crew let us which was nice.

The crew acted like they had never done this and kept barking passive aggressive orders at people. + the security line + the delay + sitting on the tarmac for 2 hours + none of the apps or signage updating with correct times

More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!

My flight was originally from SAT to MCO connecting from MCO to ORD. We got diverted to ATL and than Frontier staff there was sooo un helpful first they said they couldn’t give us any accommodation since our flight first got delayed that cancelled and now it’s 221am and I am still in ATL since they said they need to create a new flight my final destination is ORD and I have been delayed twice and cancelled. With no real help the frontier app didn’t work no email updates over all such a horrible experience

There's no seats that lean back with little leg space i wad uncomfortable the entire flight. Your charges for extra baggage is despicable and costly!!

Remind customers of the need to have passport or new ID for boarding.
