Boarding was quick and easy as always the crew is on their game as always I always have an enjoyable flight so I’m good.

Need to get on train for second flight it’s much nicer when all the gates are together for obvious reasons

Cramped, crowded aircraft. Poorly organized boarding. Tasteless crackers to eat. 40 minutes late. A standard US air travel experience.

It was my first time flying Alaska Airlines and first time flying from Santa Rosa airport. The staff was very professional and friendly. Their instructions were clear and any question was answered satisfactorily. My seat was comfortable and the in-flight beverage service very adequate for the duration of the flight. We arrived ahead of the scheduled landing time and deplaning was simple. I look forward to flying with Alaska again.

Flight attendant took my carefully folded coat and flung it across the aisle to the bin across the way. Where one of the passengers rescued it for me, because that just wasn’t right!!

the flight was delayed twice and then delayed from taking off.

Crew was very good. Problem was not Alaska Airlines’ fault, there was a horrible, squealing, screaming kid near me.

This was my first trip in years with Alaska. I don’t think I’ll do it again. The planes are old and tired looking. The seats are small with zero legroom. The JFK terminal is one of the worst I’ve been in. On this flight the pilot had to abort the landing and circle the Bay before trying again. I think I’ll stick with the usual suspects …

Flight was over an hour late, and we got notified every 15 minutes, beginning right at boarding, that it would only be 15 more minutes until we finally left about 75 minutes late. Of course, no compensation was offered.

flight took off over an hour and a half late and there was no beverage service during the flight

It was a perfect flight in all aspects! Both legs!

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.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

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.

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.

I specifically picked out right side aisle seats because my left knee sometimes needs to be stretched. But my experience this trip was that the seats were shuffled and I lost those assigned seats, resulting in me having to sit in a much less desirable position for my comfort.

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.

A bit rush for transit. Food and entertainment are not available

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.

Easiest flights I’ve ever taken. Plane was comfortable without overly crowded seating.

Terrible. Still have not received the refund from them. They sent it to some account that I don't even know. Spoke with costumer service and they are unable to help.

I didn’t like it at all. I miss my second flight because of the delay on Allegiant Air now I m stuck in MCO.

Good, but a bit late on take off after loading. Don't like charging for carry ons!

First time flying with them and will definitely fly again in the future. Crew was so nice and friendly, fought was seamless. They are simple planes, no entertainment, but it’s fine for a short flight or if you have personal devices Rates are competitive, and they did so well with keeping the flight on time after a tropical storm, where other airlines had delays and cancellations.

They boarded passengers that sat in the back of the plane first, making boarding very efficient.

I didn't even take this flight. My plans changed and I couldn't get ahold of customer service and the website kept breaking down during the attempt to change the flight. I wound up taking another airline entirely and eating the cost.

The worst flying experience ever 3 delays. No accommodations. Had to deboard the plane after being delayed.

Posted a 20minute delay but didn’t delay at all. Caused boarding issues and confusion. Also, didn’t release baggage. Took over an hour and 20 minutes to get luggage.

Flight was good, boarding was a breeze, flight attendants were friendly and professional. There was a medical issue with another passenger and the crew handled it in a calm and professional way.
