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 crew was great and everything went smoothly coming and going.

My window seat did not have a window. I chose seat 11A thinking I would have a view. I had a wall instead.

See what I wrote in the previous section. This was a terrible experience. I would like refund.. I even paid an extra $70 for an aisle seat closer to the front to ensure that I got off early enough to catch the next flight. The fact that the plane did not wait, and even left eearlier, knowing that the first flight came in late, and was moved to a terminal three train stops away is appalling. My friend that flew JetBlue, their flight was delayed and came in later and the connecting flight WAITED for them. How is it that JetBlue could do that, and Alaska could not.

This was my second time flying Alaska Airline in the 1st Class cabin. Everything was fine with the exception of the food and entertainment. The food was just ok but not what I was expecting from 1st Class. A BBQ pork sandwich and baked potato. There wasnt any in-flight entertainment. I found that odd since it was a coast to coast flight Seattle to Dulles. My sister flew 1st Class on Delta on a shorter flight ( Seattle to Cincinnati) and had an awesome meal and in-flight entertainment. I typically fly Delta but there wasn’t a flight with times that fit my schedule. I am by no means a primary donna. But when my upgrade cost over $900…I didn’t use any reward miles…I was expecting more than what I got. I will never fly Alaska Airline 1st Class again. I will stick with Delta for all my travel needs whether it’s in 1st Class or coach.

Good staff. Comfortable seats. Had to check my bag because the flight was too full.

Loved this first class flight! Awesome food, snacks and drinks. Comfortable seat with foot rest. Good movie. Very friendly crew! Only thing I would suggest is having a screen on seat back in front of me so I didn’t have to watch the movie on my phone.

The crew was very attentive, boarding was orderly. I really liked the way Alaska Airlines gives boarding passes and dropping off my bags. Very smooth.

Once we were in the air, the flight was nice and smooth. The flight was about twenty minutes late to begin with, though, and then we needed to wait to land for another plane to land first.

Flight crew great! No WiFi not great. Someone took my bag not great!

Alaska Airlines staff go out of their way to accommodate my fragile musical instrument, every time. They are unlike any other airline. I've experienced this can-do attitude on several flights with different staff, so this must be the culture of their company. I appreciate Alaska!

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!

I would like a refund for the extra cost the seat I paid for. An oversized person sat next to me and I couldn’t fit on my seat and had to move to another seat.

Boarding gate at LAX was too crowded—two gates next to one another

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.

This was a hard flight. 3 delays out of OKC (1 on the Tarmac). Delay in Atlanta coming to Dallas. total travel time was the equivalent of driving from OKC to Atlanta.

Like: flights are on time, good boarding process Can improve: planes are old, improve entertainment and make space more comfortable

Had to wait for a gate for a long time, then waited on the run way for a long time before leaving. The actual flights part was good.

The airplane was an old model, the overhead didn’t have enough room for people’s items and made boarding and boarding disappointing and stressful. Crew allowed passengers to bring more than the permitted baggage sizes.

Flying in the United States with the major airlines has become so underwhelming. A 2-3hr flight in most other parts of the world with the major carriers of the area comes with newer, CLEANER aircraft and significantly better in flight service in terms of both staff attitude and a actual meal service.
