My original booking was a nonstop flight. It got changed to a flight with a 6vhour layover that became a 7+ hour lay over. I'll never fly this airline again after this roundtrip is over.

My original booking was a nonstop flight. It got changed to a flight with a 6vhour layover that became a 7+ hour lay over. I'll never fly this airline again after this roundtrip is over.

I was surprised at how wonderful it was. The aircraft was clean. The crew was warm and welcoming and as a result the passengers were friendly. One warning the only free thing was water. I kind of liked picking wet hat I was willing to pay for and what I was willing to skip.

The flight wasn’t big on frills, which is fine with me. I flew into Islip MacArthur Airport, which saved me from having to go through LaGuardia to visit friends on Long Island. It was inexpensive and super convenient!

Great experience! This was my first time flying with them and I could not have been happier.

Airplane was newer and very clean, lots of space. Crew was great. There was no food and entertainment but that was expected so not an issue.

I like that the price is right! The airplane is clean and the staff is friendly. We landed safely, so that is always a gold star in my book! Great job!

Purposely delayed the flight by 2 hours and 58 minutes so that they would not have to give me the FAA mandated refund for a delay of 3 hours. Offered flight credit instead. All that is offered on board is water and coffee, everything else costs money. They charge you for carry on and checked bags. Would not fly again.

nice flight. no frills but a 3 hour flight I caught up on my sleep. Stan O

First time flying Breeze, was very impressed. I will use Breeze again.

The flight was rescheduled and canceled. I had to go with another airline last minute to honor my school commitment. The reimbursement is a joke -$150 for a one way plane ticket.

Boarding process, crew were good. But the seats were so uncomfortable that was all I could focus on. I literally had to sit forward so that all 3 of us could fit in row. I will try to avoid Southwest in the future for any flights over 60 minutes.

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.

Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.

Fine, but how to board on SW versus othrr airlines, is just lame. Goood staff though and all was solid otherwise.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a hell hole of an airport. It is the new LaGuardia. Everything Cobbled together. Security gates closed. Terri directional signage

I will be flying again Southwest Airlines. Friendly crew, comfortable and affordable.

The plane arrived 25 minutes late, and the Wi-Fi was slower than it usually is.

Forget beverage, they didn't even have water for half the passangers?

Seats are much much more comfortable than United, which is what I usually fly

If I pay extra for "comfort+" I expect leg room where I can stretch my legs. I was seated with an attendant's seat blocking my feet. Knee space was fine but my feet had less room than the non-"comfort+" seats. Also, don't go cheap on food when you have flights of 3+ hours. It's insulting.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

The crew was very polite as I have a few handicaps and everything was made pleasant. Check-in was easy as I was brought on board by the wheelchair assistant. One flight attendant did make sure my personal item was carefully stored under the seat in front of me. I was made to feel welcome as a customer as I made my first trip with a few disabilities. Entertainment and wifi worked quite well. The only food service were snacks and drinks. Those were okay. Overall it was a very smooth flight and encouraged me to use Delta again.

Only one side of the heafphone jack work. Crew was friendly and helpful.

Great. Flight departed early and arrived early. Deplaning and baggage claim ww were quick.

They separated our seats and moved us to the back of the plane. Hundreds of dollars and thousands of miles used and this was my platinum member experience.

AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.

Got on the plane and then needed to deboard the plane because they didn’t have any pilots?

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

The gate was too far away for the connecting flight

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.

Boarding always seems a bit chaotic. Seat spacing could leave more for leg room.

Good flight. On time. Boarding and seating was easy. Crew were really friendly, yet professional. Bathroom (by cockpit) was small but serviceable. Some the seats were showing some notable wear & tear, but were comfy. Very happy UA customer. TY! 🤛🏽💗

We arrived early and finally made it to our gate almost an hour after.

We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again

One bottle of water and a package of cookies for comfort plus. We had to literally beg a flight attendant for an extra bottle of water later in the flight due to feeling dehydrated.

Cabin was roomy enough to easily slide my carry on under the seat in front of me!

Flight boarded from Gate 39 at OGG, the farthest gate in the terminal. There were no Hawaiian themed amenities for the flight. The first class service was mediocre at best; I received not special welcome or recognition as an executive platinum member of American Advantage program. The flight attendants were more concerned with their cell phones than saying "thank you" to the passengers as we disembarked. Fortunately, the flight arrived at LAX a few minutes early.

Bigger seats. Board back to front! Disembark front to back!

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

This flight didn’t happen because AA agents didn’t let us board the flight

Plane was pretty clean, staff was friendly and helpful, flight left about on time arrived early. Took a long time to board and get off the plane - carry on items didn't have enough room so people had to move all around to find places.

The service and food needs to improve to catch up with other international flights

Would have been good to have a meal since it was a 5.5 hour flight

We boarded after several delays due to mechanical failure and a gate change. The seat cushion in the exit row was very compressed and offered no cushion, making the four-hour journey reasonably uncomfortable. The WiFi worked for a few people, but for most, it did not, and you cannot get entertainment unless you can connect—American Airlines flights do not have seatback screens, and you must use your mobile phone.
