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.

I've been loyal to Alaska Airlines for nearly 25 years and before the merger I had much better benefits. However, since the merger with Hawaiian Air, you've bumped me from group A to B or C and I now get poor selection of seats in the back of the plane.

The response was very helpful and quick. Overall, it was very professional.

WOuld have liked coffee or pretzels but other than that, crew and pilot and flight were great. Seat was great, too.

The flight 2161 was cancelled after repeated delays; for some reason the crew and not the tower located in Billings, Montana made the call. A cancelled flight is not a big deal, it happens. It was very disappointing that upon cancelling the flight it was a free for all to get to the counter for rebooking. Priority seating and first class ticket holders should have been giving priority to get on the next available flight. Most would agree that the process of moving states away, w/a cat, is stressful. A cancelled flight, 90 minutes to rebook, no place to stay, medication that was to be refrigerated and trying to find a local pet friendly hotel significantly added to the stress. Had I been able to rebook (per priority boarding SOP) I could have called the place I had just checked out of as my room most likely was just as I'd left it, including with pet supplies (which also had to be repurchased). While waiting to rebook, many of us called Alaska Airlines 800 number hoping to get a new flight; the waiting time -- this is not a joke -- was eight (8) hours, which dropped to "just" two (2) hours about 45-minutes later. Due to the cancellation I had to spend $268.75 and I still have not been refunded for the change in ticket (first class to regular). Each time I've call, five times now, the wait time was absurd, or a message of call back is given. Hopefully visiting the airport and talking with an agent face to face will be the final chapter to this experience. Alaska has been my go to air travel for years, hopefully this trip was just a hiccup. A system that forces customer's to spend hours of their time (money) to get a just due refund is not a working system. I suggest Alaska Airlines hire more representatives to handle calls; time is more valuable than money, spending 90 minutes to rebook a flight, without the difference being automatic is absurd. There are things called computers, they do amazing things. Once the flight was cancelled, only three agents were working to rebook the PAX, This too was unacceptable. First class ticket holders pay for first-class service, this should include rebooking on flights that are cancelled. I recall a time when flights were cancelled the airline would offer a hotel should the next flight not be until the following day? I had no idea that was no longer SOP; many could return home, several of us could not. The agents were pleasant once the PAX had their turn to rebook, this was true down in baggage area as well. The flight out the next day was also what I'd come to find of Alaska Airlines.

Would not let us check in our luggage. Flight was 40 minutes late, so we really did have time to check in our luggage. Could not get on another flight even for the next day, calling the Alaska service numbers provided, it stated the average wait time to speak to anyone on the phone was 8 HOURS! Alaska would not refund our tix. Never again!!!!!

The crew inside the airport for Alaska was rude, lazy and incompetent

Morbidly obese dude took half my seat. Sore shoulders back from being squeezed. Shame on the airline for not making this guy purchase two seats

I had a medical incident on the flight. The crew was very responsive and kind, making the situation as "good" as possible. (I believe they were overly cautious, but it's understandable.) My only complaint is that the seats are too small. I was so cramped for so many hours, that it exacerbated my medical incident. I will probably not be able to fly in coach anymore, and cannot afford otherwise, so it looks like flying is a thing of the past for me.

Attentive, caring. Loved the communication in the app even before boarding and while on plane from pilots.

The flight was on time and got in early which allowed us to get to our next flight.

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.

Great flight. Got to watch a movie. Smooth flight and early arrival at ORD.

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

I've been flying American mostly, and it's been very frustrating. This united flight makes me realize maybe the issue isn't flying, but the airline. United was a significantly better experience. The plane was more comfortable, with a normal amount of leg room (vs the ridiculous reductions AA has made), more comfortable seats, screens to watch movies. It was a much better experience!

We had excellent customer service despite the chaos at George Bush airport in Houston!

It isvvery small flight. No leg room . No space to put my personal item at feet.

Overall we had a good experience during our flight from San Francisco to Houston.

Airport terminal was outdated, flight was on a small jet with no wifi

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.

Delayed, toilets did not flush, pilot parked to far away from Gate

The flight was delayed about an hour for a maintenance specialist to approve the maintenance repair

This flight was delayed but it worked in my favor because my Atlanta to Dallas flight was delayed.

The staff was nice. I appreciated that I was able to take an earlier flight, even though it was last minute. The boarding process felt rather chaotic.

My flight got delayed a total of five times. And the boarding gate changed four times. most of the time the platform was not up-to-date with the changes taking place. The most discouraging part of the entire trip by far.

Returned home with a blood clot from flight homes and the uncomfortable aircraft I was on.

The crew was very kind, but no in-flight entertainment monitors and a 2 hour and 30 minute delay was extremely frustrating.

Everything was delayed and the staff sent me to the wrong gate, causing me to miss one of my flights. I arrived at my destination 6 hours later than I was supposed to.

It was good, the staff was great, and the food, was as usual, tea and biscuit. Bathroom was clean, and the plane was clean as well.

It was really a terrific experience both going and returning on AA. Staff and crew were professional.

I was able to get the AA customer Service desk to put me on an earlier flight without any issues.
